钢琴技巧急诊室：六张原创实践卡
六课独立、有边界的复核：PC-023、025、026、029、030、031。不是课程替代品，也不是六课完整视听审核。英文课名为本报告的工作译名。
逐段读完六份现有首选 ASR 共 735 段；核对 36 个指定时间点静帧（34 个不同图像 SHA-256）、手册六页的全部文字与页面图像；核验六个视频及手册 SHA-256。来源视频总长 2206.158 秒（36:46.158），这个数是来源时长，不是已观看或已听的时长。谱例只核对有关标注与布局，未逐音校订整页。本次修订只审查衍生卡片，不增加来源阅读或视听覆盖。
实际音频试听 0；连续动作观察 0；完整视听课审查 0；用户身体适合性、实际练习效果、长期保持和陌生材料迁移均未测试。没有新转写或新模型运行。
T2＝ASR 意图得到手册或所选静帧明确文字/图示的支持；只较有把握地说明作者提出了什么。T1＝主要依赖未听校 ASR，手册只支持较广主题。两者均不证明方法正确、普适或有效。O＝本报告原创练习与判断流程，尚未验证。
一次只选一张卡，先确认先修条件。所有“可能原因”、微练习、观察、复测和回曲流程均为 O，不是 Wiwi 原话。按舒适、可控的小剂量尝试；指法数字是可换的试用方案。出现疼痛、麻木或加重不适时停止，不靠用力或拉伸过关。
C4＝中央 C（Do）；在标准 88 键钢琴上，从最左端 A0 算第 1 键、黑白键都计数，C4 是第 40 键。它是中央附近一组两黑键左侧紧邻的白键，不是键盘几何中心。D4＝C4 右侧相邻白键（Re），之后 E4/Mi、F4/Fa、G4/Sol。这里是固定唱名，不代表调内级数。八度数字随 C 改变。RH/右手，LH/左手；1 拇指、2 食指、3 中指、4 无名指、5 小指。数“1-&”时把一拍等分为两份；数“1-e-&-a”时把一拍等分为四份，e、&、a 是计数标签，不是音名，也不是越数越快。“释放某键”＝让该键回升，不等于把整只手甩开。文中秒数为视频起点后的秒数，ASR 边界近似。
适用于原声钢琴上的自我观察，不需要 MIDI、麦克风、录音、唱歌或另购设备。可默数拍；若已有节拍器可选择使用。没有乐谱的具体段落不编造原曲音列或版本信息。
去重后，PC-023与PC-029是既有完整ASR文字与选帧检查的复核；PC-025、026、030、031新增完整首选转录阅读。六课此前均有部分检查。旧ASR专项账本26条与本次6条独立记录重叠1个ID，并集31；包含旧视频行的相应阅读范围并集34，不是34课完整视听。
来源条目只概述所选要点；其中“不推广、不证明、不采纳”等限制是本报告的审阅判断，不应当作作者逐字说法。后续练习步骤全部为原创。
此版已完成独立的衍生卡片复查，并保留逐项证据限制；本次整合核对来源身份、双语步骤与数值，未重新听校或观察原媒体。卡片不是已验证的学习或身体动作方案。

WPC6-023 · 保住旋律的线，不让伴奏接管
PC-023 · 第 23 天：清晰地彈出單手雙聲部
手册 PianoClinic-Book-ver1.0.pdf: 物理页27 / 印刷页26.
来源提出的想法
C23-A· 01:49.22–03:20.38 · T2: 在此课的交替声部情境中，作者建议：若旋律需要圆滑且手指能够舒适地连接，伴奏进入时不要提前释放旋律键。先确认哪条线是旋律；高音或符干方向只是线索，不是通用判定规则。C23-B· 03:21.10–04:13.62 · T2: 在作者展示的移位例子中，旋律无法继续按住时，也让伴奏一起结束，避免靠伴奏键支撑着寻找下一处旋律。这里保留例子的适用范围，不把它推广成所有复调作品的放键规则。
先修与术语
先能无踏板、轻松地弹 E4 与 F4，并在按住 E4 时轻松触及 C4。若同时触及不舒服，先只做旋律单线版；不拉开手。声部是能被单独追踪的音乐线；主声部不等于右手全部音。
症状
加上较低的音后，原本连贯的旋律变成一串断开的音，或低音突然显得更重要。
可能原因（原创假设）
可能把每一个新起音都当成前一个音的结束，或把注意力和音量一起转移到伴奏。这只是可测试的解释，不能据此诊断手部问题。
小练习（原创 O）
本卡原创，非课程谱例。右手；左手休息；踏板全部放开；4/4，每拍一个四分音符，速度慢到能轻松数四拍。先弹旋律单线一次，再加伴奏一次。可试右手 3 指弹 E4、4 指弹 F4、1 指弹 C4，但只在舒适时采用。第 1 拍弹 E4，保持到第 3 拍 F4 起音时再释放；第 2 拍加一个较轻的 C4，E4 继续按住；第 3 拍弹 F4，同时释放 C4；第 4 拍释放 F4，全体休息一拍。第 2 拍的 E4+C4 是刻意的双声部同时保留，不是误按。做完离键休息，不连续刷次数。
听与看（原创 O）
听 E4→F4 是否仍像同一条线；看 E4 的琴键是否在第 2 拍就抬起；听 C4 是否抢过旋律。不要求低声部完全听不见。靠自己的耳朵与键面观察即可。
复测（原创 O）
休息后，用同样速度再做一次旋律单线与加伴奏对照。只记录旋律是否断开、C4 是否抢声、是否舒适。若仍不清楚，且按住 E4 时能舒适地触及 C4，可做缩减版：仍用右手、左手休息、无踏板、4/4、四分音符为一拍；第 1 拍弹 E4 并保持，第 2 拍只加一次较轻的 C4，同时保留 E4，第 3 拍同时释放 E4 与 C4，第 3–4 拍休息且不按键。若同时触及不舒服，只做主练习的旋律单线版：第 1 拍 E4 保持到第 3 拍 F4 起音时再释放，第 4 拍释放 F4 并休息；不加 C4，不拉开手。所有版本都不加速。
回到曲子（原创 O）
在自己的曲子中选一处已经识别出两个声部的短段，先只弹旋律，再恢复一个伴奏音。依谱面实际时值保留和释放各声部；不要把本卡的固定拍数套进原曲。若必须大幅移位，回看 03:21–04:14 的情境并请老师核对，不硬留旋律键。
证据边界
文字与选帧支持作者提出了上述区分；没有验证示范的音量比例、完整放键时序或手腕路线。课末的下落/抬腕建议未转成身体处方。
WPC6-025 · 先确认舒适地踩放，再讨论音乐踏板
PC-025 · 第 25 天：踩踏板踩得腳好痠？
手册 PianoClinic-Book-ver1.0.pdf: 物理页29 / 印刷页28.
来源提出的想法
C25-A· 01:34.00–03:16.00 · T2: 作者把座位高度、距离、坐入深度和脚与踏板的接触位置列为应检查的变量，并区分穿鞋和赤脚/袜子的情境。它们是个人调整的起点，不是适用于每个人的厘米数或角度。C25-B· 03:16.00–04:39.00 · T2: 作者用脚踝位置示意图解释其动作想法。静帧只证实图中这样画了；不能据此验证关节运动、肌肉负荷或不适的原因。
先修与术语
能稳坐并舒适地弹单音，就可以独立做无踏板版本 A；不需要先踩踏板或能够到踏板。版本 B 另须识别最右侧的延音踏板，并能舒服地够到和控制它：按下后，某些音可在手离键后继续响。本卡只使用此踏板。不确定踏板或够不到时，保留 A，跳过 B。此课另要求先学基础踏板内容；本卡不等于完成那些课。
症状
脚为了等下一次踏板而一直紧绷，或放踏板时难以平稳回到上方。若已经痠痛，不用反复弹来证明问题。
可能原因（原创假设）
可能是接触位置、坐入深度、鞋子或踏板阻力与当前动作不合适，也可能有本卡无法判断的其他原因。一次只比较一个舒适的小调整；不把痠痛归因于某块肌肉，也不靠更大力量克服阻力。
小练习（原创 O）
本卡原创。右手 3 指可试 C4；左手休息；左踏板和中踏板不用。用四拍循环，每拍一个四分单位。只要坐着弹单音舒适，就可独立做 A：第 1 拍弹 C4，第 2 拍释放琴键，第 2–4 拍休息，全程无踏板，不必先做脚部测试。只有想做 B、当前无不适且能舒服地够到右踏板时，才先不弹琴，以右脚试一次轻松踩下和受控回放；其余身体保持舒适，脚跟可自然有支撑，不把它钉死。只有这次脚部测试也舒适才做 B：休息后，起拍前在舒适范围踩下右踏板，第 1 拍弹同一个 C4，第 2 拍释放琴键，第 3 拍让右踏板受控回到完全放开，第 4 拍休息。A 可以单独完成；B 不满足条件就跳过。适用时各做一次；不反复踩到底，不规定脚向内外移动几厘米。
听与看（原创 O）
B 的第 2 拍手离键后是否还有较明显余音？第 3 拍放踏板后余音是否收短？脚是否能平稳回来，而非弹跳或撞击？这些是本次琴与本次动作的观察，不代表测出踏板深度或音色质量。
复测（原创 O）
休息后，只复测符合条件且仍舒适的版本。A 可独立再做一次，维持同样音、拍点和音量意图；不需要踏板比较。只有 B 的先修条件与脚部测试都满足时，才维持同样音、拍点和音量意图，再比较一次舒适的小调整前后。若声音差别不清楚，记为不确定；不强踩求结果。出现疼痛、麻木或加重的不适就停止这项练习，先寻求合适的面对面评估。
回到曲子（原创 O）
在熟悉的曲子中只恢复一处已有踏板安排：先确认哪一刻手离键、哪一刻脚放开，再连回前后音。没有实际乐谱，就不为整首曲子发明踏板方案。本卡不要求使用左踏板，也不假定用户是平台钢琴。
证据边界
没有听校真实延音、检查用户的琴或观察用户坐姿。图示和作者的身体解释不是医学验证；本卡不提供治痠痛承诺。
WPC6-026 · 短音指向下一个落点，跨过小节线仍守拍
PC-026 · 第 26 天：音符分組的藝術
手册 PianoClinic-Book-ver1.0.pdf: 物理页30 / 印刷页29.
来源提出的想法
C26-A· 01:24.00–02:17.00 · T2: 作者在连续附点节奏的例子中，把短音与紧随其后的长音作为思考组合。画面确认分组框向后移；它没有把实际拍号或音符时值改掉。C26-B· 02:17.00–03:21.28 · T2: 遇到快速音串时，作者建议把后面的落点也纳入准备，即使它在下一小节。这里取用的是练习范围与预读原则；不采纳必须按八度张手等未作个体核对的动作安排。
先修与术语
拍是稳定的时间单位；小节线分隔拍组，不自动要求停顿。附点八分音符占 3/4 个四分拍，十六分音符占 1/4 个四分拍，两者共一拍。先能把一拍平均数成四小份；不会时先离键数拍。
症状
每逢短音接下一拍，或最后一个短音跨进下一小节，就多停一下；速度看似慢，却仍会卡。
可能原因（原创假设）
可能只准备了本拍或本小节，看见边界后才找下一音。也可能尚未理解时值；先分清是数拍问题还是准备范围问题。
小练习（原创 O）
本卡原创，两小节，非手册谱例。右手，左手休息，踏板全放开；2/4，以四分音符为一拍；可试 C4–D4–E4–F4–G4 用 1–2–3–4–5 指，舒适才用。第 1 小节：第 1 拍 C4 持续 3/4 拍，在该拍第 4 小份弹 D4 持续 1/4 拍；第 2 拍 E4 持续 3/4 拍，在该拍第 4 小份弹 F4 持续 1/4 拍。第 2 小节：第 1 拍 G4 持续一拍，第 2 拍释放 G4 并休息。每次新音起音时释放前一键。数“1-e-&-a、2-e-&-a；1、2”，起音在 1、1 的 a、2、2 的 a、下一小节 1。先按这些拍点弹一遍；再预先想好 D4→E4 与 F4→G4 两组，音符、时值、速度和力度意图全部不变。
听与看（原创 O）
听短音是否准时抵达下一个长音；G4 前有没有额外缝隙；长短时值仍是否为 3:1。分组不是给每组加重音，也不是把 2/4 改成别的拍号。
复测（原创 O）
休息后从第 1 小节第 2 拍开始，只弹 E4、F4、下一小节 G4，时值仍为 3/4、1/4、1 拍；再接回完整两小节。若数拍乱了，先回到离键四等分计数，不用更快速度验证。此重起测试已经给出答案，不算陌生材料迁移。
回到曲子（原创 O）
在自己的曲子里找到一串音的下一个实际落点，把练习终点延长到那里。先写清真实拍号、起音拍点和终点；不要机械地把所有短音都和后音连奏，也不要删掉谱上的休止。
证据边界
已核对分组图的意图，未逐音校订所有来源谱例，也未试听顺畅程度。ASR 的附点、指法和唱名有错误风险；练习音列是本卡自行设计。
WPC6-029 · 把慢练变成一次可检验的小实验
PC-029 · 第 29 天：慢練其實沒有用？
手册 PianoClinic-Book-ver1.0.pdf: 物理页36 / 印刷页35.
来源提出的想法
C29-A· 00:56.84–01:22.60 · T1: 作者明确承认放慢有助于反应与看谱，但要求继续检查分组、指法和移动路线。标题的问句不能当成“慢练一概无用”的结论。C29-B· 01:56.24–03:32.96 · T2: 作者区分慢速重复与保留目标动作想法的慢动作练习，并指出有些动作无法简单缩慢。所示移动路线是否适合用户，仍需实际动作和舒适度评估；不把这段话解读为每次按键都必须缓慢下压。
先修与术语
起音是一个新声音开始；放键是让键回升；两者之间的时间可以单独计划。实验只改一个变量，才较容易判断什么发生了变化。
症状
慢速能弹，但稍微连贯一点就找不到下一个键；每次只增加重复次数，仍说不清卡在哪里。
可能原因（原创假设）
可能慢速时多出了未计划的停顿，或每次指法、放键时机、找键方式都不同。先记录一个具体失误，不把“手太弱”当结论。
小练习（原创 O）
本卡原创，只检验准备与放键，不模拟快速大跳。右手可用 2 指依次弹 C4、D4、E4、D4；左手休息；无踏板；4/4，每拍为四分单位，数“1-&、2-&、3-&、4-&”。每拍正拍弹一个音，保持半拍，在 & 释放该键；下一个正拍前利用余下半拍舒适地移到下一键。第 4 拍的 & 也释放 D4，随后停下来休息。A：按现有方式做一遍，记下哪一音前出现额外等待。B：相同速度、指法和放键时机，只改变一件事：在释放前先确认下一个键在哪里，释放后再移过去。只需两遍，不要求规定腕形或冲刺速度。
听与看（原创 O）
四次起音是否仍等间距？每次释放后的空隙是否是计划的半拍，还是额外停了一下？观察下一键是否已找好；不由这四音推断大跳、快速跑动或整首曲子的机制。
复测（原创 O）
休息后，在相同速度再做 B 一次。若仍需要赶路，就把速度放到容易完成，或只做 C4→D4 两音，其余两拍休息；不为通过测试而硬加速。若原速度已舒适，可另一次尝试稍短的拍间距；这只是新条件，不能自动算改善。
回到曲子（原创 O）
回到曲子中只圈出一个失误前后的小片段，包含落点。写下一个假设和一个改动，例如先认出下一音；把音符、节奏与指法固定，比较前后。具体音符以用户实际乐谱为准。无法解释的动作问题交给面对面教学观察。
证据边界
选帧显示作者标记了错误例子与慢练要点，不能证实画面间移动的速度、加速度或肌肉负荷。本卡没有证明慢练可迁移到目标速度。
WPC6-030 · 试一个安静换指选项，再决定是否使用
PC-030 · 第 30 天：關於指法的想法
手册 PianoClinic-Book-ver1.0.pdf: 物理页37 / 印刷页36.
来源提出的想法
C30-A· 00:23.00–02:04.00 · T1: 作者把谱上指法视为可评估的建议，鼓励找到适合自己的方案后稳定使用，并练习从中间开始。这里不推断任何具体版本的指法是谁写的，也不把肌肉记忆当成唯一记忆方式。C30-B· 03:04.00–04:15.00 · T2: 作者示范在一个持续按住的音上更换手指，作为转指之外的选项。手册与画面中的指法标记支持这一意图；是否真的无再起音、保持连贯，尚未听校。
先修与术语
换指：同一个琴键保持按下时，由另一手指接手，不是把音再弹一次。1–5 指依次为拇、食、中、无名、小指。先能舒适地用右手 3、4 指分别弹 E4；两指在同一白键上的交换若觉得挤或扭，就跳过换指版。
症状
长音后去下一个音时总觉得手被前一个指法锁住，或一换指就出现第二个音头。
可能原因（原创假设）
可能还没选定后续路线，或换指时先让琴键回升了。也可能这次根本不需要换指；把它当可选工具，不当更高级的必修动作。
小练习（原创 O）
本卡原创，未复制来源的 1→5 指示范。右手；左手休息；无踏板；4/4，四分音符为一拍。A：第 1 拍用 3 指弹 E4 并保持两拍，第 3 拍用 4 指弹 F4，同时释放 E4；第 4 拍释放 F4 并休息。B 只在舒适时尝试：第 1 拍仍用 3 指弹 E4；第 2 拍让 4 指轻轻接到同一已按下的 E4，保持琴键位置，再让 3 指离开，不加压、不再击键；第 3 拍用 5 指弹 F4，同时释放 E4；第 4 拍释放 F4 并休息。若不能舒适换手指，就保留 A，任务同样完整。
听与看（原创 O）
B 的第 2 拍应没有新的 E4 音头，也没有键明显抬起再落下；第 3 拍 F4 仍应准时。音自然变弱不表示换指失败。若出现再起音，先停止并重新准备，不用更大压力把键按住。
复测（原创 O）
休息后各做一次 A 与可行的 B，只比较舒适、是否出现额外音头、F4 是否准时。选一个较合适的方案并写下；若没有明显好处，不必换。自评不是盲测，也没有证明长期稳定性。
回到曲子（原创 O）
在曲子里找一个足够长、后面需要换位置的音；先确认音符、时值与下一音，再评估是否有舒适换指方案。另练从该段开头独立起奏，不依赖前一段带入。没有手型、谱例与试听证据时，不推荐全曲统一指法。
证据边界
六张静帧只能显示不同瞬间的手与标注，不能证实中间的接触顺序或听觉无缝。3→4 的小练习是原创选择，身体适合性未测。
WPC6-031 · 把连与断变成能听见的选择
PC-031 · 第 31 天：關於樂譜的想法
手册 PianoClinic-Book-ver1.0.pdf: 物理页38 / 印刷页37.
来源提出的想法
C31-A· 02:19.00–03:30.00 · T2: 作者提醒，钢琴声音会衰减，放键与声音完全消失不是同一件事；谱面符号不能完整写出所有声响细节。图中的波形是教学示意，不是本次测量。C31-B· 03:30.00–04:11.00 · T2: 作者把 legato 的目标放在听觉上的连接感，而非唯一的手指动作。这个观点不等于可以任意忽略时值、休止或曲风，也不表示每条弧线都应解释为同一种连接。
先修与术语
连奏 legato：声音听起来相互连接；断奏/分离：音与音之间可听见间隔。休止符要求该声部在休止期间不发新音；前一个持续音须在规定的释放时点结束按键，最迟在休止开始时释放，不能把它继续按住来代替休止。其他声部可以依自己的谱继续发声；房间残响或已安排的踏板延音也可能仍可听见，这些要与该声部手指是否已经放键分开判断。本卡不用踏板。延音线连接同音并合并时值；乐句/圆滑线不能一律当作延音线。
症状
为了“每个音都连住”而舍不得放键，或把所有断奏都弹成同样短，却听不出想表达什么。
可能原因（原创假设）
可能先遵守一个固定动作规则，却没有先选声音目标；也可能把残响当成仍按住琴键的证据。用同一起音、不同释放时机的小对照来分开这两件事。
小练习（原创 O）
本卡原创。右手 C4、D4、E4，可试 1、2、3 指；左手休息；所有踏板放开；4/4，每拍一个四分单位，速度舒适。A：第 1、2、3 拍分别弹 C4、D4、E4，每个音保持半拍，在各拍的 & 释放，余下半拍不按键，第 4 拍休息。B：起音拍点完全相同，但 C4 保持到第 2 拍 D4 起音时才释放，D4 保持到第 3 拍 E4 起音时才释放，E4 到第 4 拍开始时释放；第 4 拍休息。保持大致相同的音量意图；不要靠额外压键或大幅重叠来追求连接。
听与看（原创 O）
比较 C4→D4→E4 的间隙，而不是只看手指是否挨着。第 4 拍仍能听到少量残响，也不自动表示没有放键。若两版区别听不清，写“不确定”，可做原创 C4→D4 缩减版：仍用右手、左手休息、无踏板、4/4、四分音符为一拍。A：第 1 拍弹 C4，在 1 的 & 释放；第 2 拍弹 D4，在 2 的 & 释放；第 3–4 拍休息且不按键。B：第 1 拍弹 C4 并保持到第 2 拍 D4 起音时再释放 C4；D4 保持到第 3 拍开始时释放；第 3–4 拍休息且不按键。两版都没有第 3 拍的 E4。
复测（原创 O）
休息后先决定要连还是分离，再做完整三音的对应版本一次。检查起音仍在第 1、2、3 拍：A 在 1 的 & 释放 C4、2 的 & 释放 D4、3 的 & 释放 E4；B 在第 2 拍 D4 起音时释放 C4、第 3 拍 E4 起音时释放 D4、第 4 拍开始时释放 E4。两版在整个第 4 拍都不按住任何键，并休息。先有目标再弹，不把练习重复次数当作听觉进步。
回到曲子（原创 O）
在自己的乐谱里选一处连接或分离标记，先确认它的含义与声部。保持原音符、拍子和休止，试两个舒适的声音版本后说出区别；由实际曲风和乐句决定选择。大跨度不能靠硬留前音完成时，先暂停该连接方案，不用本卡推导强拉手或全程踩踏板。
证据边界
尚未试听这些示范，也没有证明用户能分辨两版。第 31 课转写是旧稿与 0–90 秒修补稿拼接，约 90 秒有 0.2 秒重叠；本卡依据的 139–251 秒不跨接缝，但仍是未听校转写。

PianoClinic: six original practical cards
A bounded independent review of PC-023, 025, 026, 029, 030 and 031. This is neither a replacement for the course nor a full audiovisual review of six lessons. English lesson titles are working translations for this report.
All 735 segments in six existing preferred ASR files were read; 36 timestamped stills (34 distinct image SHA-256 hashes) and the full prose and page images of six handbook pages were checked; SHA-256 identities of six videos and the handbook were verified. Source videos total 2206.158 seconds (36:46.158); this is source duration, not watched or heard duration. Only relevant score annotations and layout were checked, not every note on each page. This revision reviews derived cards only and adds no source-reading or audiovisual coverage.
Actual audio auditions: 0; continuous-movement observations: 0; full audiovisual lesson reviews: 0. Physical suitability, learner outcomes, long-term retention and transfer to unfamiliar material are untested. No new transcription or model run was performed.
T2 = the ASR intention is supported by explicit handbook content or selected-frame text/diagrams; this supports attribution to the author only. T1 = mainly unverified ASR, with the handbook supporting only a broader topic. Neither proves correctness, universality or efficacy. O = original drills and decision procedures in this report, unvalidated.
Choose one card at a time and check prerequisites first. All possible causes, microdrills, observations, retests and reintegration procedures are O, not Wiwi quotations. Try small, comfortable, controlled doses; proposed finger numbers are replaceable options. Stop for pain, numbness or worsening discomfort; do not pass a task through force or stretching.
C4 is middle C (Do). On a standard 88-key piano, count the leftmost A0 as key 1 and include both black and white keys: C4 is key 40. It is the white key immediately to the left of the two-black-key group near the middle, not the keyboard’s geometric center. D4 is the next white key to C4’s right (Re), followed by E4/Mi, F4/Fa and G4/Sol. These are fixed-do syllables, not scale degrees. Octave numbers change at C. RH means right hand; LH means left hand; 1 thumb, 2 index, 3 middle, 4 ring, 5 little finger. Counting “1-and” divides one beat into two equal parts; “1-e-and-a” divides it into four equal parts. The e, &, and a are counting labels, not note names or instructions to accelerate. “Release a key” means let that key rise, not fling the whole hand away. Seconds are relative to video start; ASR boundaries are approximate.
For self-observation at an acoustic piano; no MIDI, microphone, recording, singing or new equipment is required. Count silently; an existing metronome is optional. Pitches or edition details for an unspecified piece are not invented.
After deduplication, PC-023 and PC-029 recheck existing complete ASR-text and selected-frame reviews; PC-025,026,030,031 add complete preferred-transcript reading. All six had some previous checking. The26 legacy ASR records and6 independent records overlap in1 ID, yielding31; including older video-row reading gives a union of34, not34 complete audiovisual lessons.
Source entries paraphrase selected points; qualifications such as “not generalized,” “not established,” and “not prescribed” are this review’s judgments, not verbatim statements by the author. All following exercise procedures are original.
This revision passed independent derived-card review, retaining item-level evidence limits. Integration checked source identities, bilingual steps and numbers without renewed original-media audition or movement observation. Cards are not validated learning or physical-movement programs.

WPC6-023 · Keep the melody connected without handing it over to the accompaniment
PC-023 · Day 23: Playing two voices clearly in one hand
Handbook PianoClinic-Book-ver1.0.pdf: physical page 27 / printed page 26.
Ideas attributed to the source
C23-A· 01:49.22–03:20.38 · T2: In this alternating-voice context, the author advises keeping the melody key held when the accompaniment enters, if the melody calls for legato and a comfortable finger connection is possible. First identify the melodic line; pitch height and stem direction are clues, not universal rules.C23-B· 03:21.10–04:13.62 · T2: In the demonstrated position-change example, the author releases the accompaniment with the melody when the latter cannot be held, rather than using the accompaniment key as an anchor while finding the next melody note. This is retained as contextual advice, not a release rule for all polyphonic music.

First be able to play E4 and F4 comfortably without pedal and reach C4 comfortably while holding E4. If that simultaneous reach is uncomfortable, use only the melody version; do not stretch. A voice is a musical line that can be followed separately; the melody is not every note in the right hand.
Symptom
Adding the lower note breaks up an otherwise connected melody, or the lower note suddenly attracts more attention.
Possible cause (original hypothesis)
You may be treating every new attack as the end of the preceding note, or moving both attention and loudness to the accompaniment. This is a testable explanation, not a diagnosis of a hand problem.
Microdrill (original O)
Original design, not the course score. Right hand; left hand rests; all pedals up; 4/4 with one quarter note per beat, slow enough to count four beats comfortably. Play the melody alone once, then once with accompaniment. RH 3 on E4, 4 on F4 and 1 on C4 are optional trial fingerings, only if comfortable. Attack E4 on beat 1 and hold until F4 begins on beat 3. Add a quieter C4 on beat 2 while keeping E4 down. On beat 3, play F4 and release C4. Release F4 on beat 4 and rest for that beat. Holding E4+C4 during beat 2 is intentional two-voice overlap, not an accidental extra note. Rest off the keys afterward rather than drilling repetitions.
Listen and observe (original O)
Listen for E4→F4 as one line; watch whether the E4 key rises prematurely on beat 2; listen for C4 overpowering the melody. The lower voice need not be inaudible. Your ears and direct observation of the keys are sufficient.
Retest (original O)
After a rest, repeat the melody-only and accompanied comparison at the same tempo. Record only whether the melody breaks, C4 dominates, and the action is comfortable. If unclear, and C4 is comfortably reachable while holding E4, use this reduced version: still RH, LH resting, no pedal, 4/4 with a quarter-note beat; play and hold E4 on beat 1, add one quieter C4 on beat 2 while retaining E4, release both E4 and C4 on beat 3, and rest with no key held through beats 3–4. If the simultaneous reach is uncomfortable, use only the main drill’s melody version: hold E4 from beat 1 until F4 begins on beat 3, then release F4 and rest on beat 4; omit C4 and do not stretch. Do not speed up any version.
Reintegration (original O)
Choose a short passage in your own piece where you have already identified two voices. Play the melody alone, then restore one accompaniment note. Preserve and release each voice according to the actual score rather than imposing this card’s beat counts. If a large move is required, revisit the context at 03:21–04:14 and check with a teacher; do not force the melody key to stay down.
Evidence limits
Text and selected frames support the author’s distinction; they do not verify the demonstrated loudness balance, complete release timing, or wrist path. The later dropping/lifting suggestions have not been converted into a physical prescription.
WPC6-025 · Establish comfortable pedal control before adding musical complexity
PC-025 · Day 25: Does pedaling make your foot tired?
Handbook PianoClinic-Book-ver1.0.pdf: physical page 29 / printed page 28.
Ideas attributed to the source
C25-A· 01:34.00–03:16.00 · T2: The author identifies seat height, distance, seating depth and foot contact as variables to check, distinguishing shoes from bare feet or socks. These are starting points for individual adjustment, not universal distances or angles.C25-B· 03:16.00–04:39.00 · T2: The author uses an ankle-location diagram to explain a movement idea. The stills establish what the diagram depicts, not joint motion, muscle loading or the cause of discomfort.
Prerequisites and terms
Being able to sit stably and play one note comfortably is sufficient for the independent no-pedal version A; no preliminary pedal action or pedal reach is required. Version B additionally requires identifying, comfortably reaching and controlling the rightmost sustain pedal: when depressed, some notes can continue after the hand releases the key. This card uses only that pedal. If its identity or reach is uncertain, retain A and skip B. The lesson also asks learners to study basic pedaling first; this card does not complete that prerequisite.
Symptom
The foot stays tense while waiting for the next pedal change, or the pedal is difficult to return smoothly. If discomfort is already present, do not repeat playing to demonstrate it.
Possible cause (original hypothesis)
Foot contact, seating depth, footwear or pedal resistance may not suit the present action; there may also be causes this card cannot determine. Compare only one small, comfortable adjustment at a time. Do not attribute soreness to a particular muscle or overcome resistance by pushing harder.
Microdrill (original O)
Original design. RH 3 may play C4; LH rests; do not use the left or middle pedals. Use a four-beat cycle, one quarter-note unit per beat. If sitting and playing one note are comfortable, you may perform A independently: play C4 on beat 1, release its key on beat 2, and rest through beats 2–4 with no pedal; no foot test is required first. Only if you wish to try B, are currently comfortable and can reach the right pedal comfortably, first try one easy pedal depression and controlled return without playing. Keep the rest of the body comfortable, with the heel naturally supported where possible rather than pinned rigidly. Proceed to B only if this foot test is also comfortable: after resting, depress the right pedal within a comfortable range before the first beat; play the same C4 on beat 1; release the key on beat 2; let the right pedal return under control to fully released on beat 3; rest on beat 4. A is a complete standalone option; skip B if its conditions are not met. Do each applicable version once. Do not repeatedly press against the end of travel or prescribe centimeters of foot movement.
Listen and observe (original O)
In B, is there noticeable sustain after the hand releases on beat 2, and does it shorten after pedal release on beat 3? Can the foot return smoothly without bouncing or impact? These observations concern this piano and this attempt; they do not measure pedal depth or tonal quality.
Retest (original O)
After a rest, retest only a version whose conditions are met and that remains comfortable. A may be repeated independently using the same note, beat positions and intended loudness; no pedal comparison is required. Only if B’s prerequisites and foot test are satisfied should you compare before/after one small, comfortable adjustment with the same note, beat positions and intended loudness. If the sound difference is unclear, record uncertainty rather than pushing harder. Stop this exercise for pain, numbness or worsening discomfort and seek appropriate in-person assessment before continuing.
Reintegration (original O)
Restore one already-planned pedal event in a familiar piece: identify when the hand releases and when the foot releases, then reconnect the surrounding notes. Without the actual score, do not invent a pedaling plan for the whole piece. This card does not require the left pedal or assume a grand piano.
Evidence limits
There has been no audition of the actual sustain, inspection of the user’s piano, or observation of the user’s seating. The diagram and the author’s physical explanation are not medical validation, and this card promises no relief from soreness.
WPC6-026 · Aim short notes toward the next arrival while keeping the beat across barlines
PC-026 · Day 26: The art of grouping notes
Handbook PianoClinic-Book-ver1.0.pdf: physical page 30 / printed page 29.
Ideas attributed to the source
C26-A· 01:24.00–02:17.00 · T2: In the repeated dotted-rhythm example, the author groups the short note mentally with the following long note. The frames confirm the shifted grouping boxes; the written meter and note durations are not changed.C26-B· 02:17.00–03:21.28 · T2: For a run of quick notes, the author recommends including the following arrival in preparation even across a barline. The adopted idea concerns practice boundaries and reading ahead; no unassessed octave-span preparation is prescribed.
Prerequisites and terms
A beat is a steady time unit; a barline separates beat groups and does not itself require a pause. A dotted eighth note lasts 3/4 of a quarter-note beat, and a sixteenth lasts 1/4; together they fill one beat. First be able to count a beat in four equal parts; practice counting away from the keys if needed.
Symptom
An extra pause appears whenever the short note leads into the next beat or bar, even at a slow tempo.
Possible cause (original hypothesis)
You may prepare only the current beat or bar and search for the next note after reaching its boundary. The durations may also be unclear; first distinguish a counting problem from a preparation-boundary problem.
Microdrill (original O)
Original two-bar design, not the handbook score. Right hand; left hand rests; all pedals up; 2/4 with a quarter-note beat. C4–D4–E4–F4–G4 may use 1–2–3–4–5 only if comfortable. Bar 1: on beat 1 play C4 for 3/4 beat, then D4 for 1/4 beat on the fourth subdivision; on beat 2 play E4 for 3/4 beat, then F4 for 1/4 beat on its fourth subdivision. Bar 2: play G4 for one beat on beat 1, then release G4 and rest on beat 2. Release the preceding key when the new note starts. Count “1-e-&-a, 2-e-&-a; 1, 2”; attacks fall on 1, its a, 2, its a, and the next bar’s 1. Play once with those beat positions, then prepare D4→E4 and F4→G4 as mental pairs while keeping notes, durations, tempo and intended loudness unchanged.
Listen and observe (original O)
Listen for each short note reaching the next long note on time, for any extra gap before G4, and for the long-short durations to remain 3:1. Grouping does not mean accenting every group or changing the 2/4 meter.
Retest (original O)
After a rest, begin on beat 2 of bar 1 and play E4, F4 and the next bar’s G4 with durations 3/4, 1/4 and 1 beat, then restore the full two bars. If counting breaks down, return to four equal subdivisions off the keys instead of testing at a higher speed. This restart is disclosed in advance and is not transfer to unfamiliar material.
Reintegration (original O)
Find the actual next arrival after a run in your own piece and extend the practice endpoint to it. First identify the real meter, attack positions and endpoint. Do not automatically play every short note legato into its successor or remove written rests.
Evidence limits
The grouping diagrams’ intent was checked, but all source scores were not audited note by note and fluency was not auditioned. ASR carries risks in dotted-rhythm terms, fingering terms and solfège; this card’s note sequence is original.
WPC6-029 · Turn slow practice into a small testable experiment
PC-029 · Day 29: Is slow practice actually useless?
Handbook PianoClinic-Book-ver1.0.pdf: physical page 36 / printed page 35.
Ideas attributed to the source
C29-A· 00:56.84–01:22.60 · T1: The author explicitly accepts slowing down for reaction time and reading, while asking learners to examine grouping, fingering and movement paths. The title’s question must not become a claim that all slow practice is useless.C29-B· 01:56.24–03:32.96 · T2: The author distinguishes slow repetition from slow-motion practice that retains the intended action, and notes that some actions cannot simply be slowed. Whether a demonstrated path suits the learner still requires movement and comfort assessment; this does not mean every key depression should be artificially slow.
Prerequisites and terms
An attack begins a new sound; a release lets the key rise. Their timing can be planned separately. Changing only one variable makes it easier to judge what changed.
Symptom
A passage works slowly, but becomes uncertain when made slightly more continuous; repetitions increase without clarifying where the difficulty is.
Possible cause (original hypothesis)
Unplanned pauses may have entered the slow version, or fingering, release timing and key-finding may vary between attempts. Record one concrete error before concluding that the hand is weak.
Microdrill (original O)
Original design testing preparation and release only, not simulating fast leaps. RH 2 may play C4, D4, E4, D4; left hand rests; no pedal; 4/4 with a quarter-note beat. Count “1-and, 2-and, 3-and, 4-and.” Play one note on each numbered beat, hold for half a beat, release its key on “and,” and use the remaining half-beat to move comfortably to the next key. Release D4 on the last “and” too, then stop and rest. A: play once using your current approach and note where extra waiting occurs. B: keep tempo, fingering and release timing the same and change only one thing: identify the next key before release, then move after releasing. Two passes suffice; no prescribed wrist shape or speed burst is required.
Listen and observe (original O)
Are all four attacks still equally spaced? Is each release gap the planned half-beat or an additional pause? Observe whether the next key has been identified. Do not infer the mechanics of leaps, fast runs or a whole piece from these four notes.
Retest (original O)
After resting, repeat B at the same tempo. If movement still feels rushed, choose an easier tempo or use only C4→D4 and rest for the other two beats; do not force speed to pass. If the original tempo is comfortable, a later attempt may use slightly shorter beat intervals. That is a new condition, not automatic evidence of improvement.
Reintegration (original O)
Return to one small passage around an error, including its arrival. Write one hypothesis and one change, such as identifying the next note sooner; hold notes, rhythm and fingering constant for the comparison. Use the user’s actual score for the pitches. Movement problems that remain unclear need direct teaching observation.
Evidence limits
The frames show the author’s labeled counterexample and practice points; they do not establish movement speed, acceleration or muscle loading between frames. This card has not demonstrated transfer from slow practice to a target tempo.
WPC6-030 · Try one silent finger substitution before deciding whether to use it
PC-030 · Day 30: Thoughts on fingering
Handbook PianoClinic-Book-ver1.0.pdf: physical page 37 / printed page 36.
Ideas attributed to the source
C30-A· 00:23.00–02:04.00 · T1: The author treats printed fingering as something to assess, encourages consistency once a suitable choice is found, and recommends starting from internal points. This does not establish who supplied the fingering in any particular edition, or make motor memory the only form of memory.C30-B· 03:04.00–04:15.00 · T2: The author demonstrates replacing a finger on a held note as an option alongside passing or turning the fingers. Handbook and on-screen fingering marks support that intention; an absence of reattack and maintained continuity have not been auditioned.
Prerequisites and terms
Finger substitution means another finger takes over the same depressed key without playing the note again. Fingers 1–5 are thumb, index, middle, ring and little finger. First be able to play E4 comfortably with RH 3 and 4 separately. Skip the substitution version if exchanging them on one white key feels cramped or twisted.
Symptom
A long note leaves the hand feeling trapped for the following note, or substituting a finger produces a second attack.
Possible cause (original hypothesis)
The following route may be unplanned, or the key may have risen before the new finger took over. Substitution may also be unnecessary here; treat it as an option, not a compulsory advanced action.
Microdrill (original O)
Original design, not a copy of the source’s 1→5 demonstration. Right hand; left hand rests; no pedal; 4/4 with a quarter-note beat. A: play E4 with 3 on beat 1 and hold for two beats; play F4 with 4 on beat 3 while releasing E4; release F4 and rest on beat 4. Try B only if comfortable: again play E4 with 3 on beat 1. On beat 2, gently place 4 on the same already-depressed E4, keep the key in place, and remove 3 without adding pressure or striking again. On beat 3, play F4 with 5 while releasing E4; release F4 and rest on beat 4. If the exchange is uncomfortable, retain A; the task is still complete.
Listen and observe (original O)
B should have no new E4 attack on beat 2 or obvious key rise and redepression; F4 should still arrive on beat 3. Natural fading is not a failed substitution. If a reattack occurs, stop and reset rather than applying extra pressure to hold the key down.
Retest (original O)
After resting, try A and, if feasible, B once each. Compare comfort, extra attacks and F4 timing only. Choose a suitable option and write it down; do not substitute if it offers no clear benefit. This self-comparison is neither blinded nor proof of long-term reliability.
Reintegration (original O)
Find a sufficiently long note followed by a position change in your piece. Confirm its pitch, duration and successor before assessing a comfortable substitution. Also practice starting that passage independently of the preceding one. Without evidence from the hand, score and sound, no universal fingering for the piece is recommended.
Evidence limits
Six stills show the hand and annotations at different instants, not the intervening contact sequence or seamless sound. The 3→4 exercise is an original choice with untested physical suitability.
WPC6-031 · Make connected and detached playing an audible choice
PC-031 · Day 31: Thoughts on the score
Handbook PianoClinic-Book-ver1.0.pdf: physical page 38 / printed page 37.
Ideas attributed to the source
C31-A· 02:19.00–03:30.00 · T2: The author points out that piano sound decays and releasing a key is not identical to all sound vanishing; notation cannot specify every sonic detail. The displayed waveform is a teaching illustration, not a measurement made in this review.C31-B· 03:30.00–04:11.00 · T2: The author frames legato as an audible sense of connection rather than one compulsory finger action. This does not permit arbitrary disregard of durations, rests or style, nor mean that every curved line has the same interpretation.
Prerequisites and terms
Legato is an audible connection between notes; detached playing has audible separation. A rest requires that voice to make no new attacks during the rest; its preceding sustained note must cease being held at its scheduled release, no later than the start of the rest, rather than remain held in place of the rest. Other voices may continue according to their own notation, and room resonance or planned pedal sustain may remain audible; distinguish these from whether that voice’s finger has released its key. This card uses no pedal. A tie joins identical pitches and combines their durations; a phrase or slur mark must not automatically be read as a tie.
Symptom
Trying to connect everything makes releasing keys difficult, or every detached note is made equally short without a clear audible intention.
Possible cause (original hypothesis)
A fixed movement rule may be taking priority over the sound goal, or residual resonance may be mistaken for a key still being held. Compare the same attacks with different release times to separate these issues.
Microdrill (original O)
Original design. RH C4, D4, E4 may use 1, 2, 3; left hand rests; all pedals up; 4/4 with a comfortable quarter-note beat. A: play C4, D4 and E4 on beats 1, 2 and 3 respectively, holding each for half a beat, releasing on its “and,” and leaving the remaining half-beat without a key held; rest on beat 4. B: use exactly the same attack positions, but hold C4 until D4 begins on beat 2, D4 until E4 begins on beat 3, and E4 until the start of beat 4; rest on beat 4. Keep a similar loudness intention. Do not seek connection through extra key pressure or large overlaps.
Listen and observe (original O)
Compare the gaps in C4→D4→E4 rather than only whether the fingers remain close. A little residual sound on beat 4 does not automatically mean a key remains held. If the versions are hard to distinguish, write “uncertain” and try this original reduced C4→D4 version: still RH, LH resting, no pedal, 4/4 with a quarter-note beat. A: play C4 on beat 1 and release on its “and”; play D4 on beat 2 and release on its “and”; rest with no key held through beats 3–4. B: hold C4 from beat 1 until D4 begins on beat 2, then release C4; hold D4 until releasing it at the start of beat 3; rest with no key held through beats 3–4. Neither reduced version includes E4 on beat 3.
Retest (original O)
After resting, choose connected or detached sound before playing the corresponding full three-note version once. Check that attacks remain on beats 1, 2 and 3: A releases C4 on “1-and,” D4 on “2-and” and E4 on “3-and”; B releases C4 when D4 begins on beat 2, D4 when E4 begins on beat 3, and E4 at the start of beat 4. Both versions hold no key throughout beat 4 and rest for that beat. Set the goal first; practice repetition counts are not evidence of auditory improvement.
Reintegration (original O)
Choose one connection or separation marking in your score and first identify its meaning and voice. Keep the written pitches, beats and rests, compare two comfortable sound versions, and describe the difference; choose in light of the actual style and phrase. If a wide span cannot be connected without force, set that connection strategy aside rather than inferring forced stretching or continuous pedaling from this card.
Evidence limits
The demonstrations have not been auditioned, and the user’s ability to distinguish the versions is untested. Day 31’s transcript combines an older output with a repaired 0–90-second prefix, with about 0.2 seconds of overlap near 90 seconds. This card’s 139–251-second evidence does not cross that seam but remains unverified ASR.
