音阶与调式：材料要放回语境
只用D、F、A也可以编一个小句子：同样的音，换休止或结束音，句子就会变化。先做这个选择，再给音阶和调式命名。前置：音名、音程。Dorian是多利亚调式，Aeolian是爱奥利亚调式。
【通用乐理】音阶列出音高材料，调式还涉及中心音与相对该中心的音程关系。把 C 大调的白键从 D 开始弹，并不会自动使整段音乐获得 D Dorian 的中心感；持续低音、终止位置与旋律重心会影响听觉判断。
【作者观点】《即兴幼幼班》手册 PDF-IV 第 5–17 页逐渐增加音高选择，同时要求关注节奏、留白与自己听到的张力。第 17 页提供入门和弦/调式对应，但也安排整段在同一调性材料中即兴；它不意味着每个和弦一出现就必须换一套音阶。
【本库综合】可以把即兴决策拆成：时间上的句子、和弦上的落点、可用音域。先稳定其中两项，再改变第三项；这样才能判断某个变化究竟产生了什么作用。
同主音比较（本库自编）
在 D–F–A–C 的小七和弦上，分别比较包含 B 与 Bb 的短句：
D4 F4 A4 B4 A4 F4 D4D4 F4 A4 Bb4 A4 F4 D4
【通用乐理】第一句呈现 Dorian 的大六度，第二句呈现 Aeolian 的小六度。这里只比较局部色彩，不声称单句足以确定整首作品调式。保持相同节奏、音量与低音，更容易听出改变来自哪个音。
读写和听觉互相检查
【作者观点】Wiwi 的文字移调器文章强调音程拼写不能只按琴键的半音位置处理。W-TRANSPOSE。
【通用乐理】例如把 Db 向上移大三度：字母先到 F，再核对四个半音，得到 F；若把 D# 向上移大三度，则需写 F##。十二平均律中可与别的音名同键，不代表和声意义相同。
【本库综合】练耳时不只问“认出音名了吗”，还问“能不能唱出关系、在另一个调重现、解释为何这样拼写”。绝对音高记忆与相对音感是不同维度。尚未独立验证的“人人都能”“最快”等学习效果宣称不写成定论。
音阶熟悉度怎样迁移
【作者观点】《如何练音阶？》把固定上下行练习放回实际作品的多种排列方式中讨论。N-SCALES-PRACTICE；本轮读取全文文字，谱例音频尚未播放。
【本库综合】能从主音匀速上行，不足以证明从任意音转向、落在指定和弦音或同时维持另一声部也熟练。可固定一个调和一段自编短句，分别改变入口、方向和节奏，记录哪一种条件真正造成停顿。不要用一遍顺利的固定音阶替代这些不同能力的检查。
从选择和反馈开始
【作者观点】IV-001 的开头 ASR 候选与20、50秒画面，以减少音高选择帮助开始即兴；IV-002 的25、42、60、70秒画面及手册实际第6页，支持对自己习惯的观察；IV-003 的15、48、65、82、93秒画面及手册第7页，支持刻意拓展节奏材料。这是全文 ASR、手册与30个静帧的有限核对，没有听校或完整动态观看。
【本库综合】可以把“生成内容”和“回顾习惯”安排成两个步骤。生成时保留一个明确约束，回顾时只选一个可观察指标；下一次只改变这一项，才能判断自己是否重复了惯用答案。这个组织方式也可用于旋律写作与伴奏设计。
名称、音列和指法不是一个答案
【作者观点】新读的FOPP-29 把调号、关系大小调与常用指法联系；实际PDF第69–71页相关正文已核对，既有中文第4–6段已比较。提取稿后的指法表没有因此算作全表视觉核验，历史命名与键盘设计评价仍只是作者叙述。
【通用乐理】A自然小调上行为 A B C D E F G A；和声小调为 A B C D E F G# A。一种常见古典旋律小调练习，上行 A B C D E F# G# A，下行 A G F E D C B A。标明采用哪一种音列和语境，不把“小调”当作唯一固定列表，也不把这种练习写法强加给所有风格。
【本库综合】判断音列正确与指法是否能连接上下文，仍是两个测试。单八度终点的指法不自动适用于继续多个八度；记下入口、方向、终点和前后声部条件。
把一个差异看清，再给整段音乐命名
先比较 D E F G A Bb C D 与 D E F G A B C D：只改了第六级，Bb变B。前者是D自然小调的音列，后者是D Dorian的音列。对照音阶差异图，再回到上面的同主音短句；音列辨认和整段音乐中心感的判断是不同任务。
【作者观点】扫描书PDF-NC-BOOK实际第31–45页的OCR文字已读，原图第32/36/42/45页已核对，涉及大小调、小调变体及部分现代调式。第45页是下一章开头，不代表该章已读完；歌曲、历史与流行程度举例没有全部独立验证。本库不复刻其口令、歌曲谱例或排列叙事。
【通用乐理】音程图上等距的“半音”刻度不是等差的赫兹（Hz）频率。在十二平均律里，相同半音数对应相同的频率比例；越高的音区，同样一个半音的Hz差值越大。扫描书第32页将半音刻度说成频率数线，容易让初学者混淆这两种轴。
【本库综合】“大调开心、小调悲伤”可以是作者的听感描述，不能充当辨认算法。同样，常见旋律小调上下行练习不是“古典作品下行绝不能升高六、七级”的禁令。判断实际音符要看局部和声、旋律走向和原谱。图解明确列出它展示的音列，未把任何一列说成整首作品只能使用的音。
【对照】FOPP-44给即兴设定的多年等待说法，不应当作开始创作的门槛。好和弦即兴文章则强调在已有材料和限制中作选择。先用熟悉的少量音尝试一个有起止的小句，再检查它能否回应目标；这是一项本库建议的入门任务，不等于已经掌握所有即兴风格。该文的职业、历史和减压效果宣称也不因全文已读而自动成立。
同一批音，中心和上下文仍然重要
【通用乐理】D大调五声音阶可写为 D E F# A B；B小调五声音阶可写为 B D E F# A。两者音级集合相同，但中心不同；仅将一串音从B开头读出来，还不能证明整段音乐建立了B中心。五声音阶表示一个八度内五个不同音级，并不专指某一种文化或固定五音配方。
【来源边界】扫描书实际第46–60页文字已读，其中第54页原图确认OCR错认的E；第49页C Mixolydian及小七度符号已看图。书中风格、情绪、普及程度、歌曲分析与文化起源说法未全部独立核验。堆叠纯五度是一种音高构造；它本身不证明所有文化的历史起源，也不要把纯律3:2与十二平均律五度当成完全同一频率比例。配和弦时还要观察旋律重音、停留时长和上下文，而不是把“音都在同一音阶”当成每种效果都合适的保证。
同一套材料、不同中心，与升高一个音
【通用乐理／原创纸上自查】先写 C D E F G A B 与 A B C D E F G，圈出各自约定的中心C与A。七种音高类相同，但中心不同；这是关系大小调的入口，不是“同音异名”。再把第二列G改成G♯：得到A和声小调所用的音列，调的关系与音阶的具体形式要分开说。仅靠音列还不能证明实际乐曲建立了哪个中心。
若已有半音与拼写基础，可在纸上检查G♯小调的第七级。自然形式为F♯；升高半音后写F𝄪，在十二平均律键盘上与G同键，但保留F字母以表示第七级。答案：F♯到G♯为2半音，F𝄪到G♯为1半音。双升号表示把自然音升高2半音，并非把已经带升号的音再升高2半音。无需把这串音强行交给一只手弹。
【源文纠正】FOPP§29第6项混淆关系小调与自然小调；中文附加演示误用同音异名；实际72／印71页表1.2的G♯行误写升七级。见Q-094／Q-095／Q-098。英文表格已有60格独立检查，中文对应表仍缺，0/60格双语检查；本例不是补出的原译表。
参阅原创音阶伴读：按七个级进和八个音位核音名与调号，区分来源指法串、终止语境及个人实奏适用性；不把未决的B大调左手串用于一对一纸上配对。
Scales and modes: put materials in context
You can make a tiny phrase using only D, F and A. Change its rests or ending and the same notes make a different phrase. Make these choices before naming scales and modes. Prerequisites: note names, intervals. Dorian is 多利亚调式; Aeolian is 爱奥利亚调式.
[General theory] A scale lists pitch material; a mode also involves a center and intervals relative to that center. Starting C-major white notes on D does not automatically make D sound like the center of D Dorian. Sustained bass, endings and melodic emphasis affect that perception.
[Author's view] PDF-IV, pp. 5–17, gradually adds pitch choices while emphasizing rhythm, space and perceived tension. Its p. 17 introduces chord/mode associations, but also uses one tonal collection across a passage. It does not require a new scale whenever a chord changes.
[Our synthesis] Separate improvisation decisions into temporal phrases, chordal arrival notes and available register. Stabilize two and change the third to make the effect of a change easier to assess.
Same-tonic comparison: our original material
Over the minor-seventh chord D–F–A–C, compare phrases containing B and Bb:
D4 F4 A4 B4 A4 F4 D4D4 F4 A4 Bb4 A4 F4 D4
[General theory] The first highlights Dorian's major sixth; the second highlights Aeolian's minor sixth. This compares a local color, without claiming that one phrase establishes a whole work's mode. Keep rhythm, loudness and bass the same to isolate the changed note.
Check notation against hearing
[Author's view] Wiwi's text-transposer article emphasizes interval spelling beyond keyboard semitone positions. W-TRANSPOSE.
[General theory] Transposing Db upward by a major third reaches the letter F; checking four semitones gives F. Transposing D# upward by a major third requires F##. Equal keyboard pitch in twelve-tone equal temperament does not make different spellings harmonically equivalent.
[Our synthesis] Ear training should ask more than whether a note name was recognized: can the relationship be sung, reproduced in another key and explained in notation? Absolute-pitch memory and relative hearing are separate dimensions. Unverified promises about everyone succeeding or the fastest method are not treated as established findings.
How scale familiarity transfers
[Author's view] “How to practice scales” places fixed ascending/descending patterns among many arrangements found in actual works. N-SCALES-PRACTICE: full article text read; score-example audio not played.
[Our synthesis] An even ascent from the tonic does not establish fluency in turning from any note, arriving on a chosen chord tone or maintaining another voice. Keep one key and an original phrase, then vary entry, direction and rhythm separately. Record which condition causes a pause. One successful fixed scale does not replace those checks.
Begin with choice and feedback
[Author's view] Opening ASR candidates and frames at 20/50 seconds of IV-001 support beginning with fewer pitch choices. Frames at 25/42/60/70 seconds of IV-002 and handbook p. 6 support observing one's habits. Frames at 15/48/65/82/93 seconds of IV-003 and handbook p. 7 support deliberately expanding rhythmic material. This is limited cross-checking of complete ASR text, handbook and 30 still frames, without listening verification or full moving-video review.
[Our synthesis] Separate generating material from reviewing habits. Keep one clear constraint while generating; review one observable measure afterward. Change just that measure next time to check habitual answers. This organization can also support melody writing and accompaniment design.
Name, pitch collection and fingering are separate answers
[Author's view] Newly read FOPP-29 connects key signatures, relative major/minor and common fingerings. Relevant actual PDF text on pages 69–71 and Chinese paragraphs 4–6 were checked. Following fingering tables are not thereby fully visually verified; naming history and keyboard-design judgments remain the author's account.
[General theory] Ascending A natural minor is A B C D E F G A; harmonic minor is A B C D E F G# A. A common classical melodic-minor exercise ascends A B C D E F# G# A and descends A G F E D C B A. Name the collection and context. Minor is not one fixed list, and this exercise convention is not imposed on every style.
[Our synthesis] Correct pitches and fingering that connects in context are separate tests. A one-octave endpoint fingering does not automatically fit a multi-octave continuation. Record entry, direction, endpoint and surrounding voices.
Inspect one difference before naming the whole passage
Compare D E F G A Bb C D with D E F G A B C D: only degree six changes, from Bb to B. The first is the D-natural-minor collection; the second is D Dorian. Use the scale-difference diagram, then return to the same-tonic phrases above. Identifying a collection differs from judging a passage's tonal center.
[Author's view] OCR text of PDF-NC-BOOK physical pages 31–45 was read, with images of pages 32/36/42/45 checked. These cover major/minor, minor variants and some modern modes. Page 45 begins the next chapter; that chapter is not complete. Song, historical and prevalence claims were not all independently verified. We do not recreate its mnemonic, song scores or narrative sequence.
[General theory] Equally spaced semitone marks do not represent equal frequency increments in hertz (Hz). In twelve-tone equal temperament, equal semitone intervals have equal frequency ratios; the Hz difference for one semitone increases in higher registers. Calling the semitone scale a frequency number line on scan page 32 can confuse these two axes.
[Our synthesis] Major-happy/minor-sad can describe an author's response, but is not an identification algorithm. Likewise, the familiar ascending/descending melodic-minor exercise is not a ban on raised sixths and sevenths in descending classical passages. Check local harmony, melodic direction and the actual score. The diagram names the collections it shows without claiming that a whole work must use only one of them.
[Comparison] The years of waiting proposed in FOPP-44 should not become a prerequisite for beginning to create. NiceChord's improvisation article emphasizes choices within existing material and constraints. Try a short phrase with a beginning and ending using a few familiar pitches, then check whether it meets the goal. This is our beginner task, not mastery of all improvisational styles. Reading the article does not establish its career, historical or stress-relief claims.
A shared pitch collection still needs a center and context
[General theory] D major pentatonic can be written D E F# A B; B minor pentatonic can be written B D E F# A. They share pitch classes but have different centers. Reading the list from B alone does not establish B as the center of a whole passage. Pentatonic means five distinct pitch classes per octave, not one culture or a single fixed formula.
[Source limits] Scan text on physical pages 46–60 was read. The image of page 54 confirms an E misread by OCR; C Mixolydian and the minor-seventh symbol on page 49 were visually checked. Style, emotion, prevalence, song-analysis and cultural-origin claims are not all independently verified. Stacked pure fifths are a pitch construction, not proof of every culture's history; a pure 3:2 fifth and an equal-tempered fifth are not identical frequency ratios. Over a chord, consider melodic emphasis, duration and context rather than assuming every scale member always gives the desired effect.
Shared material, a different center, and one raised note
[General theory / original paper self-check] Write C D E F G A B and A B C D E F G, circling their stipulated centers C and A. The seven pitch classes match but the centers differ: an entry point to relative keys, not enharmonic respelling. Change G in the second collection to G♯ to obtain the material of A harmonic minor; distinguish the key relationship from the particular scale form. A collection alone does not prove which center an actual work establishes.
With semitone/spelling prerequisites, check G♯ minor’s seventh degree on paper. Its natural form is F♯; raising it one semitone gives F double sharp, sharing G’s key in twelve-tone equal temperament while retaining the letter F for degree7. Answer: F♯ to G♯ spans2 semitones; F double sharp to G♯ spans1. A double sharp raises the natural note by2 semitones, not the already-sharp note by another2. Do not force this collection into a single-hand playing task.
[Source corrections] FOPP section29 entry6 conflates relative and natural minor; an added Chinese demonstration misuses enharmonic; table1.2’s G♯ row on physical72/printed71 misspells the raised seventh. See Q-094/Q-095/Q-098. The60 English table cells have independent inspection, but missing Chinese counterparts leave0/60 bilingual cells; this example is not a reconstructed translation table.
See the original scale companion: check spelling and signatures across seven steps and eight positions, separating source finger patterns, ending context and individual performance suitability. Exclude the unresolved B-major left-hand string from one-to-one paper matching.
