钢琴技巧：声音目标与动作组织
同一串音，可以弹对却在连接处停住。技巧练习先找这个具体问题，再看指法与动作如何配合。前置：拍与音名；可先做E05的短句。
【作者观点】技巧手册 PDF-PC 第 4、39 页明确保留个体差异与多种解决办法；第 7、10、11 页把手指形态、力度和活动协调放在实际情境中讨论。这里摘取研究问题，不把手册改写成逐日替代课程。
【本库综合】评价动作时同时观察：声音是否实现、节奏是否稳定、移位是否可重复，以及身体是否舒适。只看“手型像不像”会漏掉时机、负重和释放；只听转写也看不到这些细节。
指法与连续性
【作者观点】PDF-PC 第 37 页讨论印刷指法的可调整性、保持已选指法、从中段起弹、两手重新分配与按住音时换指。旧证据 PC-030 的 124–145 秒及 140 秒静帧支持“优先标注不自然的指法”；本轮尚未重新听校该时段。
【本库综合】指法是一条通过句子的路径，不能只在单个音上判好坏。选择后用三个测试检查：从前文进入、从难点本身开始、接到后文。若只从曲首才能成功，先记录为“换入口尚未成功”；可能涉及记忆提示、定位或准备时间，不能仅凭一次失败确定原因。
分组与落点
【作者观点】PDF-PC 第 30 页强调跨拍/跨小节的分组。本轮已查看完整页面。旧 PC-026 166.6–191.92 秒的转写与 185 秒静帧把快速音串后的目标音纳入组内；这是选段证据，不代表全课复核。
【本库综合】练习区间可从最小困难单元开始，但应包含连接音。小节线是时间组织线，未必是手势或乐句的边界。分组改变的是注意与动作组织，不授权改写原有音长。
连奏、释放与踏板
【作者观点】PDF-PC 第 26、38 页把 legato 和谱面符号理解为有连续差异的音乐表达。第 29 页讨论踏板的身体位置与音色用途。旧 PC-031 148–194 秒及 155/175 秒静帧涉及余音衰减和踏板深浅；口述尚未听校。
【本库综合】需要分别记：键何时放开、弦何时被止音、听起来何时不再突出。这几个时刻可能不同。踏板会改变共鸣与混合程度，不能以“有踏板/无踏板”两档概括全部结果，也不能从一句 ASR 推定脚踝动作幅度。
新增选段核对
【作者观点】PC-001 的 659–697 秒口述候选强调手指与更大部位的配合，并保留不适用的极快速情境；660 秒画面文字明确纠正“完全不动个别手指”的误解。300、304、308 秒画面可见单音示范的不同位置，但没有据此测量关节轨迹或验证省力效果。
【作者观点】PC-029 的 116–213 秒口述候选与 130、138、205 秒画面都把慢练联系到目标动作。153、157、161、165 秒显示移位示范的不同位置。这些是指定时间点的静态检查，不能称为完整动态观看。
【本库综合】学习者应区分“理解教师要说明的对比”和“自己已能复现”。完整 ASR 能帮助找片段，却不能证明手腕幅度、速度效果、主观舒适度或音量稳定性；本库不把讲解中的克数、厘米数推广成通用动作处方。
触键阶段与作者之间的差异
【作者观点】FOPP-11 将触键分成下键、保持与释放，提醒保持阶段不应变成持续强压。它同时给出一些具体机构和断奏深度解释；这些解释没有全部被本库独立证实。
【对照】该节对一般断奏下键深度的表述，与技巧手册 PDF-PC 实际第17页（印刷16）的按键建议并不相同。两份文字没有构成控制了乐器、速度与声音目标的对比实验，因此本库保留差异，不把它们合成为通用下键深度比例。判断自己的结果仍需实际声音与动态动作证据。
移位问题先分清时间、位置和手的条件
【来源边界】新核PC-017/018/019全文ASR、手册实际21–23页及每课4静帧。第17课讨论含大量黑键的快速段落；第18课提出个人的连续移位方法，并保留时间间隔较长时可以不同处理的条件；第19课在缩短移动距离之外，明确考虑手大小与舒适度。静帧没有测量力量、疲劳、命中率或连续轨迹，不能据此给所有人指定相同角度、厘米数或手型。
【本库综合】先在谱上标出“何时离开、下一音何时开始、哪些音要保持”，再请能够观察完整演奏的教师协助选择动作。一个指法缩短了移动距离，也可能增加伸展需求；不能只用一项指标决定。PC017的ASR把黑键宽度识别成公里，已隔离，不把猜测的单位写入教学事实。
源译文的动作范围与机构引用
【翻译复核】FOPP-11第2段（实页27／印页26）说下键开始较慢，译稿却扩成整个过程放慢。起始阶段和完整动作不是同一范围；这里只修复译意，不证明作者的加速／琴槌解释，也不据此制定统一触键动作。
【证据边界】同节第3段的括号引用§80三角钢琴机构图第5项，原句没有比较立式与三角琴。译稿新增的琴种区别不应当作证据；后续已核§80原图实际226／印刷225页，第5项标为Center pin felt bushing；实际运动及琴种比较仍未验证。抽查说明记录范围与Q-059、Q-063，原译稿未修改。
宽度困难：先调整任务，不用硬撑证明进步
【作者观点】FOPP-46列出撑掌、拉伸与抬指方法；第9段反对过高抬第4指，第10段又要求尽可能高。这种上下文张力不能压成一条统一动作规则。原书的快撑、固定角度和增幅承诺没有在这里得到生理或训练效果验证，故不转成本库的身体训练处方。
【翻译复核】第9段的Everyone指人，现译却变为每根手指；第4段另添加了英文没有指定的掌面朝上。Q-074／Q-075恢复对象和限定，不据此给出替代的跨度测试姿势。相关段实104–107／印103–106。
【本库综合】原创项目替代路径：假设谱上同一时刻有C4、E4、G4、C5，先纸面标出4个音及外侧跨度12半音。这个读谱结果不要求手一定够到。若原谱的同时奏法不适合当前条件，记录困难，先做节奏、音名或声部任务；请能看到实际手与琴的教师协助选可及的配置、分配或材料。任何分解、删音或重新分手都应标为练习改编，不能悄悄当作原谱完成。下次复测的是明确约定的任务，而非强迫跨度变大。
【证据边界】FOPP-60实150–153／印149–152包含个人经历和医疗断言。本库不采用镜前姿态自测疾病、特定按摩必治、短休息即可修复损伤或由练琴等级判断安全等规则；发烧、药物和呼吸机制段也不成为练习步骤。腕管综合征是正中神经在腕处受压的病症，诊断与治疗须结合个体评估，部分病情可能需要手术。AAOS说明不能替代个人诊疗。
若练习出现疼痛，停止引发疼痛的动作；持续或反复疼痛、麻木、无力应交合适的医疗人员评估。指导音乐动作的教师与诊治疾病的专业人员承担不同工作。纸上任务可以保留练习项目的进展，不用病名猜测替代反馈。这里没有制定治疗方案、返练剂量或伤害发生率。
先确定哪个声部何时放开
【本库综合】六张实践卡给出更细的自查入口。先把“起音在哪一拍”“键保持多久”“哪些声部休止”分开，手指或踏板方案随后选择。双声部卡先确认旋律线；换指卡以没有新增起音为目标；连断卡的两版都保留最后一拍休止。不同声部同时计时，不能把两条线的时长相加当整小节长度。
【证据边界】这些是原创小例与有条件的来源归纳。6课已有完整首选ASR阅读、36时间点静帧和6手册页核对，仍无原音听校、连续手脚动作、身体适合性或学习效果验证。PC-023与PC-029为复核；PC-025、PC-026、PC-030、PC-031补完整首选转录阅读。不要用静帧替自己诊断用力或宣称防伤。
名称、方向与验收条件分别记录
【源译边界】§46第7项的lifting是抬指，hand是手；下一项的arm才是手臂。纠正词义并不认可固定按住其他手指、最大抬升或负重方案。§30第28项还提醒我们：不能保留“提早”这个动作目标，却删掉“音阶保持平顺”的声音条件。§35谈音与音之间，不是要求整个颤音过程绝对不动。见Q-097／Q-101／Q-108／Q-109。
【本库记录设计】将一条任务拆为：想听到什么、具体动作是否有人观察、检查发生在哪个时间段、当前未知什么。比如记录“这一小段起音间隔更接近目标，手指动作未观察”，不要写“手型正确、损伤已恢复”。这是证据记录方式，不是新的身体训练或健康结论。
把细节变成可结束的小任务
第二组六张Clinic卡把两音连接、短音收尾、断奏时长、和弦前景、重叠与两声部释放分开观察。第三组六张处理同键起音、路线预想、黑白键定位、音长、响度与换指前的释放。每卡保留先修、小步骤、立即检查、休息后的复测及回到实际乐句；P预备可独立选择，不能把单音完成记成多音任务通过。
这是新编教学任务，来源只提供有限问题与教法线索。12课均已有完整ASR文字与选帧记录，本批属于复核，不是新增12课完整视听。没有从静帧推出腕部轨迹、关节安全或动作因果，也没有要求复制作者的固定高度或角度。
先说清持续到哪里，再讨论动作
新增Clinic细节卡把“换音”拆成旧音何时结束、新音何时开始和两者之间是否有休止。PC-027的原创比较保留E4两拍，同时C4只从第2拍到2-&；松开C4不代表E4也结束。PC-015只设计非滑奏的分离单音预备，不要求模仿课中擦键动作。原始声音和连续动作仍未复核，不能由文字或静帧判断身体原因。
源译短纠正另将轻触键、练习曲体裁和TU／TO的作者术语分开，避免把译文措辞直接变成动作命令。
原创机构标签伴读帮助读懂击弦机部件名称，七项现代部件等价仍未决；它不是修理或动作处方，也不解决其他引文中的部件歧义。
Piano technique: sound goals and movement organization
The right notes can still pause at a join. Begin technique work with that concrete problem, then examine fingering and movement together. Prerequisite: beat and names; try the tiny phrase in E05.
[Author's view] PDF-PC, pp. 4/39, allows individual differences and multiple solutions. Pages 7/10/11 place finger shape, loudness and coordination in context. We extract questions for study, rather than rewriting a daily substitute for the course.
[Our synthesis] Assess sound, rhythmic stability, repeatable travel and comfort together. Looking only at hand shape misses timing, loading and release; transcription alone cannot show them either.
Fingering and continuity
[Author's view] PDF-PC, p. 37, discusses adjusting printed fingering, retaining a chosen fingering, starting mid-passage, redistributing hands and substituting fingers on held notes. Historical PC-030, 124–145 seconds, and its 140-second frame support prioritizing unusual fingering marks. This segment has not been listened to again in this task.
[Our synthesis] Fingering is a route through a phrase, not a judgment about one note. Test entry from before, starting at the difficulty, and continuing afterward. If only the opening works, record that a changed entry has not yet succeeded. Memory cues, location or preparation time may be involved; one failed attempt does not identify the cause.
Groups and arrival notes
[Author's view] PDF-PC, p. 30, discusses groups crossing beats and barlines; the full page was viewed. Historical PC-026, 166.6–191.92 seconds, and its 185-second frame include the target note after a fast run. This is excerpt evidence, not full-lesson review.
[Our synthesis] Begin with the smallest difficult unit but include its connecting note. A barline organizes time; it need not delimit a gesture or phrase. Grouping changes attention and movement organization, not the written durations.
Legato, release and pedals
[Author's view] PDF-PC, pp. 26/38, treats legato and notation as expressive continua; p. 29 discusses pedal position and tone. Historical PC-031, 148–194 seconds, and frames at 155/175 seconds concern decay and pedal depth. Speech remains unverified by listening.
[Our synthesis] Record key release, string damping and loss of audible prominence separately; they may occur at different times. Pedals affect resonance and mixing, beyond a simple on/off distinction. One ASR sentence cannot establish ankle travel.
Newly checked excerpts
[Author's view] Speech candidates at 659–697 seconds of PC-001 discuss fingers working with larger body parts and an exception for extremely fast situations. The 660-second frame explicitly corrects the idea of completely immobile individual fingers. Frames at 300/304/308 seconds show positions in a single-note demonstration, without measuring joint trajectories or establishing effort reduction.
[Author's view] PC-029, 116–213 seconds, and frames at 130/138/205 seconds connect slow practice with intended movement. Frames at 153/157/161/165 seconds show different positions in a travel demonstration. These are selected stills, not a complete moving-video review.
[Our synthesis] Understanding a teacher's comparison and reproducing it oneself are different accomplishments. Complete ASR can locate excerpts but cannot verify wrist travel, speed effects, subjective comfort or stable loudness. Grams or centimeters in explanations are not universal prescriptions here.
Related: rhythm, practice, E05.
Keystroke phases and differences between authors
[Author's view] FOPP-11 separates pressing, holding and releasing a key, warning against continued strong pressure during the hold. Its specific mechanical and staccato-depth explanations have not all been independently established here.
[Comparison] Its general staccato-depth description differs from PDF-PC, physical p. 17 (printed 16). The texts do not constitute a comparison controlling instrument, speed and sound goal. We preserve the difference rather than combining them into one universal depth ratio. Assessing one's result still requires actual sound and moving-action evidence.
Separate timing, position and hand conditions in a move
[Source limits] New checks of PC-017/018/019 cover complete ASR text, handbook physical pages 21–23 and 4 stills each. Lesson 17 concerns fast, black-key-heavy passages. Lesson 18 proposes a personal method for repeated moves while retaining alternatives for longer time gaps. Lesson 19 considers hand size and comfort alongside reduced travel. Stills do not measure force, fatigue, accuracy or continuous trajectories, and cannot prescribe identical angles, distances or hand shapes for everyone.
[Our synthesis] First mark departure time, the next onset and any notes that must continue. A teacher who can observe the complete performance can then help choose movements. Fingering that reduces travel may increase stretch; one metric cannot decide the choice. PC017 ASR renders key width in kilometers; the segment is quarantined rather than silently guessing a unit for a teaching fact.
Source-translation limits: motion scope and mechanism references
[Translation review] In FOPP-11 paragraph 2 (physical 27/printed 26), the author describes a slower beginning; the translation expands this to the entire keystroke. Beginning and whole movement are different scopes. This repairs meaning only, without validating the acceleration/hammer account or prescribing a universal keystroke.
[Evidence limits] The bracket in paragraph 3 points to item 5 of the §80 grand-piano action diagram; it does not compare upright and grand pianos. The translation’s added distinction is not evidence. A later check of the original §80 diagram at physical226/printed225 identifies item5 as Center pin felt bushing; actual motion and instrument-type comparisons remain unverified. The sample report records scope and Q-059/Q-063; the source translation is unchanged.
Wide-span difficulty: adapt the task without forced stretching
[Author's view] FOPP-46 lists palm spreading, stretching and lifting methods. Paragraph9 cautions against excessive finger4 lift, while paragraph10 asks for maximal height. This contextual tension cannot become a universal motion rule. Fast stretching, fixed angles and reach-gain guarantees have not received physiological or training-effect validation here and are not turned into physical prescriptions.
[Translation review] Everyone in paragraph9 refers to people but becomes every finger; paragraph4 additionally inserts palm-up orientation not specified in the English. Q-074/Q-075 restore the subject and limits without supplying an alternative reach-test posture. Relevant text:physical104–107/printed103–106.
[Our synthesis] Original project alternative: suppose C4, E4, G4, C5 share an onset in a score. First mark the4 notes and outer span of12 semitones on paper. This decoding result does not require physically reaching the chord. If simultaneous execution is unsuitable under current conditions, record the difficulty and work on rhythm, note names or voices. Ask a teacher who can observe the hand and instrument to help choose accessible configurations, allocations or material. Any arpeggiation, omission or hand redistribution must be labeled a practice adaptation rather than silently counted as the original score completed. Retest the agreed task, not forced enlargement of reach.
[Evidence limits] FOPP-60, physical150–153/printed149–152, mixes anecdotes and medical claims. We do not adopt mirror-posture diagnosis, guaranteed massage cures, tissue repair through brief rest or playing-level safety rules. Fever, medication and breathing-mechanism passages do not become practice steps. Carpal tunnel syndrome involves median-nerve compression at the wrist; diagnosis and treatment depend on individual assessment, and surgery may be appropriate in some cases. AAOS information does not replace personal care.
If playing causes pain, stop the painful movement; persistent or recurring pain, numbness or weakness warrants assessment by an appropriate healthcare professional. A teacher guiding musical movement and a clinician diagnosing illness have different roles. Paper tasks can preserve project progress without disease guesses replacing feedback. No treatment plan, return-to-playing dose or injury-incidence ranking is provided here.
First decide which voice releases when
[Our synthesis] The six practice cards provide finer self-checks. Separate attack beat, key-hold duration and voice-specific rests before choosing fingers or pedal. The two-voice card first identifies melody; substitution aims for no added attack; both connected/detached versions retain a final-beat rest. Voices run simultaneously, so adding their durations does not yield bar length.
[Evidence limits] These are original miniatures and conditional source summaries. Six lessons have complete preferred-ASR reading,36 timestamped stills and6 handbook-page checks, without original-audio audition, continuous hand/foot observation, physical-suitability or learner-effect validation. PC-023 and PC-029 are rechecks; PC-025, PC-026, PC-030 and PC-031 add complete preferred-transcript reading. Stills do not diagnose your effort or establish injury prevention.
Record names, directions and acceptance conditions separately
[Source-translation limits] In section46 entry7 lifting denotes lifting and hand denotes the hand; arm appears in the next entry. Correct wording does not endorse fixed held-down fingers, maximal lifts or loading routines. Section30 entry28 also reminds us not to retain an early-motion goal while dropping its smooth-scale sound condition. Section35 refers to between notes, not absolute immobility throughout a trill. See Q-097/Q-101/Q-108/Q-109.
[Our record design] Separate the intended sound, whether anyone observed the actual motion, the checked time interval and remaining unknowns. For example, write “onset intervals in this short passage are closer to the target; finger motion was not observed,” rather than “hand position is correct and injury has healed.” This is evidence recording, not a new bodily exercise or health conclusion.
Turn a detail into a small task with an endpoint
Six group2 Clinic cards separate two-note connection, a short ending, detached duration, chord foreground, overlap and two-voice release. Six group3 cards address same-key attacks, route prediction, white/black-key location, duration, loudness and release before a finger change. Each retains prerequisites, small steps, immediate checks, a retest after rest and return to an actual phrase. Preparation P is independently selectable; a single-note success does not pass the multi-note task.
These are newly designed tasks; sources supply only bounded questions and teaching suggestions. All12 lessons already had full-ASR-text and selected-frame records: this batch is a rereview, not12 newly completed audiovisual lessons. Stills establish no wrist trajectory, joint safety or movement causation, and the tasks require no replication of fixed source heights or angles.
Define the endpoint before discussing movement
New Clinic detail cards separate when the old note ends, when the new note starts and whether a rest lies between them. The original PC-027 comparison holds E4 for two beats while C4 lasts only from beat2 to2-and; releasing C4 does not end E4. PC-015 designs only separated-single-note, non-glissando preparation, without requiring imitation of the source sweep. Original sound and continuous motion remain unchecked; text/stills cannot establish a physical cause.
Short source corrections also separate light touch, the étude genre and attributed TU/TO terms, avoiding direct conversion of translated wording into movement commands.
The original action-label companion explains component names while retaining seven unresolved modern-part equivalences. It supplies neither repair nor movement prescriptions and does not resolve component ambiguity in other citations.
