Basis for this skill
The basis is the songbook corpus (《同一首歌》, 《2012 流行歌曲精选》, 《我的流行吉他》1/2/4), the measured reverse ARR-SPEC, and the porting of the general layer; there is no single book that discusses Chinese-language pop arrangement methods. ★ This skill will not fabricate style claims just to appear complete— each item below is marked with its source basis.

1. Required before starting
| Required | How to ask |
|---|---|
| ① Mandarin or Cantonese | ★ The melodic constraints of the two are completely different（§3、§5） |
| ② Era | The "style" of Chinese-language pop varies greatly across eras (1990s vs 2010s vs now) |
| ③ Whether the reference is Chinese-language or foreign | ★ Determines how to use the §2 porting table |
| ④ Lyrics first or music first | ★ In Chinese this decision matters far more than in English (§3.2) |
2. ★ Porting table
Chinese-language pop borrows heavily from J-POP and the West at the arrangement level; this itself is not a problem—the problem is borrowing in the wrong place.
| Technique | Can it be brought into Chinese-language pop? | Explanation |
|---|---|---|
| J-POP harmonic vocabulary(royal road progression, Komuro, canon) | ✅ Fully portable, and already mainstream | See mc-progressions |
| J-POP's A–B–sabi three-part structure | ✅ Portable, already mainstream | mc-form §2.2 |
| J-POP's B melody (pre-chorus) | ✅ Portable | In Chinese it is the "pre-chorus" |
| Western Verse–Chorus two-part form | ✅ Portable | Earlier Chinese-language pop was mostly this |
| city pop instrumentation and timbre | ✅ Portable | See mc-style-citypop-rnb |
| Melodic density of J-POP | ⚠️ Half-transferable | ★ Japanese has one sound per syllable; Chinese has one sound per character, but characters are "heavier"— copying Japanese-style density directly makes Chinese unclear in articulation |
| Liaison/reduced-vowel handling in English pop | ❌ Not transferable | Chinese has no reduced syllables; forcing it in becomes mumbling |
| English flow in rap | ⚠️ Half-transferable | Chinese rap has different stress patterns. ★ For the mixed division of labor between rap + Chinese style, see mc-style-hiphop §8.1 and mc-workflow §2.4 |
| Position of large melodic leaps | ⚠️ ★ Constrained by tone-melody mismatch（§3） | This is the hardest local constraint in Chinese-language music |
★ One criterion：
Harmony, instrumentation, and structure can be borrowed freely; the melodic pitch contour cannot — it is locked by tone.
3. ★ Tone-melody mismatch: the hardest local constraint in Chinese-language music
3.1 What it is
Mandarin has four tones,each character carries its own pitch contour. If the direction of the melodic interval entering this character conflicts with the character's tone pattern, listeners will hear it asanother character— this is calledtone-melody mismatch。
Lyric-writing library lw-tone-check 's judgment model(the repository internally has a detector script for the same model, not released with the package):
contour = TONE_PITCH[t][1] - TONE_PITCH[t][0] # 本字的调型
incoming = notes[i] - notes[i - 1] # 进入本字的音程
if contour > 0 and incoming < 0: 风险 # 阳平该升却下行
elif contour < 0 and incoming > 0: 风险 # 去声该降却上行
elif contour == 0 and abs(incoming) >= 3: 风险 # 平调被大跳带出走向
★ Note the key point of this model: what is compared isthe melodic interval entering this characterandthis character's own tone pattern， not"the tail note of the previous character vs the head note of the next character". (The latter was the first version's formulation; it cannot detect the standard textbook cases.)
3.2 Three consequences for arrangement
Judgment and correction belong to the lyric-writing library, but they in turn constrain arrangement:
- ★ The position of large melodic leaps is not free — whichever character a large leap lands on, that character has a risk of tone-melody mismatch.
→ This limits
mc-melodythe leap arrangement in §3 - ★ "Melody first" costs more in Chinese-language music — writing the melody first and then fitting lyrics, the lyricist must simultaneously satisfy meaning, rhyme, and no tone-melody mismatch.Lyrics first or revising while writing is more common
- The same melody with different lyrics must be rechecked — the second verse has different lyrics, so the tone-melody mismatch risk points are also different.
→
form[].noteshould mark "this section's melody is the same as A1 but the lyrics differ, needs rechecking"
3.3 Self-check actions
Read each section's melody and lyrics aloud together. If it sounds like another character, it is a tone-melody mismatch. For a more systematic method, use the lyric-writing library
lw-tone-check§2.3: check only three types of positions — each section's highest note, each line's first character, and large-leap landing points.
4. Corpus status: what can be found
4.1 Reverse ARR-SPEC (3 entries)
In the repository's measured corpus, style_layer: mc-style-chinese-pop those with 3 entries：
| Metric | Value |
|---|---|
| Median BPM | 137 (range 131–141) |
| Median number of sections | 10 |
| Median duration | 217 seconds |
⚠ 3 entries are not enough to support any style claim. Listing them here only illustrates "what can be found". ★ The 137 above is only the median of three entries,Do not treat this as the BPM of Chinese-language pop. For the BPMs that can be found in the scores, see §4.3.
4.2 Songbook corpus
| Book | Page | Nature |
|---|---|---|
| Same Song · 20th-Century Chinese Pop Song Gems | 569 | A 20th-century song collection, used as the selection pool for the four-alignment table |
| 2012 Pop Song Selections | 140 | Used for harmony/form statistics |
| My Pop Guitar 1 / 2 / 4 | 100/111/107 | ★ With chord markings and section-by-section harmonic analysis, suitable for progression statistics |
4.3 Songbook measurements (five songbooks, 931 entries, only score parameters stored)
Four Chinese-language books (Same Song, 20th-century works, 379 songs; 2012 Pop Song Selections, 102 songs; My Pop Guitar, three volumes, 83 songs; total n=564):
| Metric | Value |
|---|---|
| Key (movable-do tonic; for modulations, the starting key) | F 15%、C 13%、G 13%、D 10%、♭B 10%、E 9%、A 9%、♭E 8%（n=550） |
| Time signature | 4/4 69%、2/4 25%、3/4 4%、6/8 2%（n=546） |
| BPM, counting only those with a number marked in the score | P10 58 / median 84 / P90 120（n=78，Almost all from the 20th-century works in Same Song） |
| Tempo and expression terms | Medium tempo 58, slightly slow 28, slightly fast 24, slowing down 18, affectionately 12, passionately 9, freely 8 |
| Genre marked in the score | Film insert song, film theme song, Xinjiang folk song, Shaanxi folk song, opera excerpt |
How to read：
- The key distribution in Chinese-language songbooks is very flat: the five keys F, C, G, D, and ♭B account for sixty percent, and no single key exceeds twenty percent; contemporary works (the 2012 selections and the guitar scores) are mainly in C, G, D, and ♭E, and the guitar scores make heavy use of a capo to return to C/G shapes.
- ★ The BPM of contemporary Chinese-language pop still has no measurements in this database: the 78 with numbers are almost all 20th-century ethnic and film/TV songs, and the median of 84 cannot be extrapolated to today's pop songs; the 2012 selections and the guitar scores give only tempo terms (medium tempo, slightly slow) and no numbers. To get BPM you have to wait for an audio corpus.
- 2/4 time accounts for a quarter, a characteristic of 20th-century songbooks; contemporary Chinese-language pop is almost entirely 4/4.
The keys, chord loops, and skeletons of English fake books (1955–1986 Billboard top twenty, n=367) are in mc-case-studies reference §1.2, as a European and American point of reference.
4.3 ⚠ One statistics attempt and its results (an honest record)
What was done: from the notes of the My Pop Guitar series, extract the "1=X" key and the section-by-section harmonic progression, convert to scale degrees, and count four-chord windows.
Results: only 10 songswere parsed, and the most common windows are
I V I V(3 times),V I IV V(3 times),I IV IV I(2 times)……
Conclusion：★ The sample is too small, and the results are generic progressions, so they do not constitute a Chinese-language characteristic. It was not written up as a "characteristic progression of Chinese-language pop" — that would be a misuse of the data.
5. Cantonese: declared as a later-added layer
The user's exact words：
"Cantonese and Korean should not block our progress; at the architectural level we are layered + compositional anyway, so they can be added later."
So Cantonese here is a declared interface, not an empty hole:
| Item | Description |
|---|---|
| Assonance | Cantonese has nine tones, and the constraints are much stricter than Mandarin's four tonesmuch stricter. The determination belongs tothe lyric-writing library |
| What this skill can say | is only "it exists and is stricter"; it does not give specific rules |
★ Do not invent Cantonese rules before finishing the source text. Cantonese tone-melody matching has a precise system; anything guessed will be wrong.
5.1 What the periods mean for arrangement (Wong Chi-wah, Forty Years of Cantonese Pop)
| Period | Foundation | What it means for arrangement |
|---|---|---|
| 1949–1959 | Two sources: the Mandarin-era songs passed down from ShanghaiMandarin-era songs, and the golden-ageCantonese opera and Cantonese music（p0047） | Cantonese songs had two foundations from the start: one is the dance-hall band of the era songs, the other is the gongs and drums and banghuang of Cantonese operatic tunes. To write an "old-school Cantonese flavor," first choose the foundation |
| 1960s | Manipulated by Cantonese films, the style was eithertoo Cantonese-opera-like, or a **Westernization that "tries to paint a tiger but ends up with a dog"** (p0048); mostly old tunes with new lyrics, such as lyrics set to Cantonese opera tunes (p0048) | ★ The two failures named in the book are exactly the pits most easily fallen into today when doing "retro Cantonese": once the gongs and drums sound, it becomes Cantonese opera; once Westernization goes too far, it becomes neither fish nor fowl |
| 1980–1982 | Taiwan campus folk songs swept in, encouraging young people to write their own songs (p0051); the market was sluggish, and record companies brought in new singers and new lyricists (p0051–0052) | Folk guitar instrumentation entered Cantonese songs: mainly acoustic guitar, light instrumentation, lyrics weighted more than the melody |

The language (Mandarin/Cantonese) must be written in—it affects the timbre library chosen by the backend |
| Coupling with LYR-SPEC | ★ In Chinese this coupling is much tighter than in English (§3.2). Shared fields are in mc-workflow §5.1 |
8. Must pass after writing
- ClarifiedMandarin or Cantonese
- Checked §2 transfer table; borrowed techniques are in the "transferable" column
- Large leaps in the melody have been considered for tone-lyric mismatch
- Sections with the same melody but different lyricsare marked as needing review
- The direction of lyric-melody coupling (lyrics first/melody first) isintentionally chosen
- ★ The statistics of the 10 songs in §4.3 are not cited as stylistic features
- ★ No Cantonese rules were invented
- Every cited stylistic claim can state its basis
