What it does
Mc Harmony is an agent skill from jtydhr88/music-composition-skills. Functional and colour harmony (和声：功能与色彩) - choosing chords for a melody and then upgrading them without over-cooking. The three functions and three cadence types, the measure-by-measure harmonization procedure, substitution rules, seventh chords, and the colour techniques (slash chords, secondary dominants, two-fives, tritone substitution, subdominant minor, modal flavours, sus4, tensions, cliche lines, passing diminished, pedal point, blue notes) organised as a nine-step reharmonization checklist with an…
Its SKILL.md is about 2.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `reference.md`).
The repository describes itself as: Professional agent skills for composing and arranging popular music. The licence is MIT.
When your agent uses it
- Harmonizing a melody
- A progression is bland
- A section needs a specific colour (wistful
- Chromatic bass)
Example prompts
- “/mc-harmony”
Workflow steps
10 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 7adca0c. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Mc Harmony loads about 2.2k tokens when it runs. Until then it costs about 195 tokens; SKILL.md has 698 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

The three functions and three cadence types, the measure-by-measure harmonization procedure, substitution rules, seventh chords, and the colour techniques (slash chords, secondary dominants, two-fives, tritone substitution, subdominant minor, modal flavours, sus4, tensions, cliche lines, passing diminished, pedal point, blue notes) organised as a nine-step reharmonization checklist with an explicit stop rule.

和声：功能与色彩（Harmony）
这个 skill 分两半，用的时候要分清你在哪一半：
| 半 | 干什么 | 在 §几 |
|---|---|---|
| 功能 | 给旋律配上说得通的和弦 | §2–§5 |
| 色彩 | 把说得通的和弦变得好听 | §6–§7 |
★ 顺序不能反。 先有功能骨架，再上色彩。 直接从色彩起手的结果是"每个和弦都很高级、连起来不知道在干嘛"。

1. 动笔前必填
| 必填 | 问法 |
|---|---|
| ① 调 | 大调还是小调、哪个调。所有级数记号以它为准 |
| ② 和声节奏 | 一小节几个和弦？★ 全曲一小节一个是最典型的套路 |
| ③ 这段要什么色彩 | 用 §6 的词回答，不是"好听一点" |
| ④ 哪里必须最稳、哪里必须最不稳 | 决定终止式放哪 |
2. 三功能
| 功能 | 性格 | 成员 |
|---|---|---|
| T（Tonic） | 稳定 | I、VIm（VIm 是 I 的"替身"） |
| S（Subdominant） | 轻度不稳，推向 D | IIm、IV |
| D（Dominant） | 不稳，想回 T | V、VIIm(♭5)（V 压倒性常见） |
D 的不稳必须"解决"到 T，这个心理需求正是音乐前进动力的来源。
★ IIIm 被排除在这张表外——它是变色龙，既能当 T 也能当 D，见 §6。
3. 三种终止式
| # | 型 | 感觉 | 例 |
|---|---|---|---|
| 1 | T → D → T | 像"起立、鞠躬、坐下"，简单有力 | C→G→C（I→V→I）、Am→G→C（VIm→V→I） |
| 2 | T → S → D → T | 张力逐步上升，一举解决到 T——最令人满足 | C→F→G→C、Am→Dm→G→C |
| 3 | T → S → T | 不经过 D 就回 T；S→T 通常是 IV→I，即阿门终止（变格终止） | C→F→C |
同功能连用：同功能的和弦可以串起来。 例 C→Am→F→Dm→G→C（I→VIm→IV→IIm→V→I）—— I+VIm 串成 T，IV+IIm 串成 S，整体仍是 T→S→D→T。
3.1 ★ 终止式与情感：唯一一家管歌词的（Kachulis）
本库三家和声来源都不管歌词在说什么，这一层出自 Kachulis《The Songwriter's Workshop: Harmony》（p0163–0174）：
| 终止 | 情感 |
|---|---|
| 完全终止 V → I | 坚定 |
| 半终止（停在 V） | 不确定，制造紧张 |
| 虚伪终止 | 暧昧的惊喜，且三个落点各不同：V → VImin 悲哀；V → IV 惊喜；V → VI 大三和弦 明朗欢快的惊喜（p0169） |
| 变格终止 IV → I | 宗教感、精神性 |
| 混合终止（大调借小调 ♭VI – ♭VII – I） | 悲喜混合，摇滚布鲁斯尤其有效 |
各调式的完全终止长得不一样（p0163–0165）：大调 V–I；小调 ♭VII–Imin 或 V–Imin；布鲁斯 V7–IV7–I7；混合利底亚 ♭VII–I；★ 多利亚没有完全终止。
3.2 家与离家：三种段落形状（p0176–0193）
| 段落 | 形状 |
|---|---|
| 主歌加副歌 | 家 – 离家 – 家 |
| 主歌 | 家 – 离家，停在 V 推进副歌 |
| 桥段 | 离家 – 离家，以非 I 起、结束在 V，张力最大 |
副歌两种造法：只用一个终止反复；或只在主题句上用终止，★ 主题句出现之前避免主和弦（p0182–0187）。 段落衔接：主歌停 V，副歌起 I 是完全终止式衔接；副歌起 VImin 是虚伪终止式衔接，有意外感（p0191–0193）。
★ 段落对比的四条和声判据（p0195）：每段起始和弦不同；每段至少一个新和弦；只在副歌出现完全终止；每段乐句长度不同。 写完对一遍这四条，四条都没做到的两段听起来会是同一段。
3.3 和弦色彩改词义：润色词语与润色乐句（Kachulis p0149–0160）
同一个音上的同一个词，配不同和弦，意思就变：大三和弦充满希望、强力和弦有力自信、小三和弦悲伤内省、七和弦忧郁性感（p0149–0150）。 本库以前没有"和弦 → 歌词意义"这条线。
润色乐句的工序（p0152–0160）：找出乐句里两三个重要音，做一张多列的候选和弦表，每列对应一个小节，然后组合着试；同一小节放两个和弦能造一点动力。 配套一个用途分组（p0082）：IImin–IIImin–IV–V、IV–V、IImin–V、VImin–V 这一组是"倾向 V"的进行，专门用来制造紧张、通往副歌。
4. 逐小节配和声的流程
- 确认基本盘：写出这个调的 I、IIm、IV、V、VIm 及其功能，再写出三种终止式
- 逐小节列候选：取这一小节的旋律音，找出构成音包含它们的自然音和弦
- 旋律音正好等于某和弦的组成音 → 直接候选（如 A·F·C → F）
- 多个和弦都包含 → 并列候选（如 B♭·D → B♭ 或 Gm，都是 S）
- 用终止式裁决：如果前三小节已经构成 T→S→D，第四小节就该回 T——挑 T 功能的候选
- 结束规则：全曲落在最稳定的 I 上最好
- T 既是终点也是起点：在 T S D T S T D T 这样的功能链里，一个 T 常常被前后两个终止式共用
4.1 一个走完的例子（F 大调，3/4，8 小节）
候选表：F(I,T)、Gm(IIm,S)、B♭(IV,S)、C(V,D)、Dm(VIm,T)
| 小节 | 旋律音 | 候选 | 裁决 |
|---|---|---|---|
| 1 | A·F·C | F（构成音完全吻合） | F（T） |
| 2 | B♭·D | B♭ 或 Gm（都是 S） | 都行 |
| 3 | E·G·C | C | C（D） |
| 4 | A | F 或 Dm（都是 T） | 前三小节已 T→S→D，这里回 T |
| 5–8 | 同法 | B♭ → F → C → F | S→T→D→T，落在 I |
结果：F → B♭(或Gm) → C → F(或Dm) ／ B♭ → F → C → F
经验法则：先尽量往终止式框架里套，是进步的捷径。
★ 失效条件：真实歌曲里违反理论的例子比比皆是。 硬要"终止式必须绝对成立"，本身就会产出不自然的进行——保持弹性，凡事有例外。
4.2 两条初学者的代换规则（及它们的边界）
IIm 与 IV 互换（S 功能组内）——这条最稳。任达敏《流行与爵士和声学》把 ii、IV、vi 归进同一个下属功能组，"最常见的就是下属功能组和弦的相互替代"（p0134）：I-IV-V7-I 换成 I-ii7-V7-I 或 I-vi-V7-I，声部级进都更顺（p0135）。爵士乐里这条走得更远——IV 换成 ii7 之后，实践中 ii7 反而比原本的 IV 更常见（p0280）。
I 用 IIIm 代换：两套判据不一样，别混用
- 走"变色龙"这条路（见 §2、§6），IIIm 顶替 I 的时候色彩比 VIm 更暗，也更容易被听成朝 D 方向的过渡。
- 任达敏那套古典／爵士功能划分里，iii 反而归进属功能组，和 V、vii°7 同组（p0134）；他明说 iii 对 I 的解决力比 V 弱，"iii-I 的和声力度比较弱"，不建议让 iii 顶替终止式里的 I（p0135）。他给 I 在大调里更标准的代换对象其实是 VIm：因为 I 的和弦音大半被 VI 和弦包含，但这条只在大调成立，换用之后 I 后面的 V 通常也要跟着改写成 ii-V（p0279）。
- 连用副和弦本身有代价：一段旋律里正和弦几乎全被 iii、vi、ii 这类副和弦替换、又落在 VIm 上，听感会整个滑向关系小调，不再是原来的大调（p0118、p0120 例1-20）。
5. 小调（以和声小调为基础）
小调的功能表与三终止式同构，但 V 要用大三/属七（来自和声小调的升七级）， 否则 D→T 的解决力消失。详细的自然/和声/旋律小调对照表见 reference.md。

6. 色彩手法：症状 → 手法速查
| 想要 | 首选手法 |
|---|---|
| 更有推进力／更鲜明 | 副属和弦、二五 |
| 更爵士／更时髦 | 张力音、连锁二五、裏和弦 |
| 切なさ（怅惘）、一抹阴影 | 下属小调（S.M）、IIIm7 |
| 半音下行的低音线 | 分数和弦、裏和弦、经过减和弦、クリシェ |
| 同一个和弦挂太久，想要内部运动 | クリシェ、sus4、保续音 |
| 避开平白属七的套路感 | 属小调、裏和弦、不解决的 V7sus4 |
| 忧郁／酷／即兴感 | 布鲁斯与蓝调音 |
| 整段气氛大换 | 转调引子（→ mc-modulation） |
| 整段重配 | §7 九步表 |
6.1 各手法一句话
| 手法 | 做什么 |
|---|---|
| 分数和弦 | 指定低音，做出平滑或半音的低音线 |
| IIIm7 | ★ 变色龙：既能当 T（I 的代理）又能当 D（V 的代理）。切换看上下文 |
| 副属和弦（Sec.D） | 在任何"临时充当 T 的和弦"前面放它的 V7 |
| 二五（ii–V） | 把一个属和弦拆成 IIm7→V7，推进力加倍 |
| 裏和弦（三全音代换） | V7 → ♭II7。低音走半音，味道更冲。不合适时加 ♭5 |
| 下属小调（S.M） | IV→IVm(6)，或用 ♭VI△7／♭VII7 代换。怅惘感的主要来源 |
| 旋法味（多利亚 IV／属小调） | 借调式色彩，避开功能和声的直白 |
| sus4 | 延迟解决。不解决的 V7sus4 可以完全避开属七的套路 |
| 张力音（9/11/13） | 加色不改功能 |
| クリシェ（半音线） | 和弦不动，内声部半音移动——治"和弦挂太久" |
| 经过减和弦 | 填进大二度的空隙 |
| 保续音（Pedal） | 低音不动，上面换和弦 |
| 布鲁斯／蓝调音 | ♭3、♭5、♭7 的擦音 |
（每一条的完整用法、可用张力音表、禁用组合见 reference.md。）
7. ★ 九步重配和声表
给一个平淡的进行，按顺序试。每一步都以耳朵为最终裁判。
| # | 做什么 |
|---|---|
| 1 | 七和弦化（三和弦 → 七和弦）。不要到处都加，看整体平衡 |
| 2 | 代理替换：I ⇄ IIIm7/VIm7，IV ⇄ IIm7，V7 ⇄ VIIm7(♭5)/IIIm7 |
| 3 | 插入副属：每个"临时充当 T 的和弦"前面试着放它的 V7 |
| 4 | 属和弦二五化：每个属七都检查能否拆成 IIm7→V7 |
| 5 | 属和弦裏代换：要半音低音或更冲的味道时，V7 → ♭II7 |
| 6 | 借下属小调：IV→IVm(6)，或 ♭VI△7／♭VII7，做怅惘 |
| 7 | 大二度空隙插 dim7、分数和弦做平滑低音、sus4 做延迟解决 |
| 8 | 撒张力音：按 reference 的表配 9/11/13 |
| 9 | ★ 最后问自己：是不是做过头了？ |
7.1 ★ 第 9 步是这张表最重要的一步
"绝不要把和弦切得过碎。" 直白的摇滚/流行尤其要提防啰嗦——简单最好的情况同样多。
自检动作：把升级后的版本和原版轮流放。 如果说不出升级版好在哪里，就退回去。 和声的复杂度不是分数，是手段。
7.2 逐步升级演示
同一个骨架 C → Am → Dm → G（I → VIm → IIm → V，循环进行）：
| 步骤 | 进行 | 用了第几步 |
|---|---|---|
| 原始 | C → Am → Dm → G | 自然音三和弦 |
| 七和弦化 | C△7 → Am7 → Dm7 → G7 | 1 |
| 插副属 | C E7 Am C7 F D7 G（I III7 VIm I7 IV II7 V） | 3 |
| 二五化 | C → Bm7(♭5) → E7 → Am → Em7(♭5) → A7 → Dm7 → G7 | 4 |
| 裏 + 张力 | Em7 → E♭7 → Dm7 → D♭7 → C△7(9)（半音下行低音收尾） | 5+8 |
| 加怅惘 | C → Am → Fm6 → G7sus4 → G7 | 6+7 |
★ 注意这六行不是越往下越好。它们是六种不同的东西。 选哪一行由 §1 的必填③决定，不由"高级程度"决定。
8. 三个常用骨架（详表在 mc-progressions）
| 名 | 进行 | 功能 |
|---|---|---|
| 循环进行 | I → VIm → IIm → V | T→T→S→D。可以无限重复，骨架中的骨架 |
| 逆循环 | IIm → V → I → VIm | S→D→T→T。即从 S 段起头的循环进行；大调里比循环用得还多 |
| 卡农型 | I → V → VIm → IIIm → IV → I → IIm → V | ★ 它的魅力在于从各和弦的构成音能抽出一条级进下行的旋律线，到最后一个和弦转而向上——"一线希望忽然出现"的情绪效果 |
逆循环最常见的发展：重复两次、第二次落在 I；或重复时把末尾的 VIm 改成 VI 大三：
Dm→G→Em→Am ／ Dm→G→C→A
9. 与 ARR-SPEC 的字段对应
| 字段 | 本 skill 的哪一节 |
|---|---|
form[].harmony（级数） | §2–§5 |
form[].harmony_letters（字母） | 同一进行的双记，本库硬约定 |
| lint #9（至少一段有调外和弦或转调标记） | §6、§7 |
★ 双记号是硬约定：级数用来思考和移调，字母用来交接和编译成 prompt。 只写一种视为未填。
10. 写完后必过
- 先有功能骨架，再上色彩，不是反过来
- 每一段的和声能说得出它的功能链（T S D T…）
- 全曲落在 I 上（要余韵才反着做，且写明理由）
- 和声节奏不是全曲一小节一个
- 至少一段有调外和弦（lint #9）
- 跑完九步表后问过"是不是过头了"，且说得出升级版好在哪
- 级数与字母双记齐全
- 色彩手法是按 §1④ 的需要选的，不是按"高级程度"选的
