What it does

Mc Style Jpop is an agent skill from jtydhr88/music-composition-skills. J-pop as a style layer (日式流行风格层) - the chorus-centred design discipline that distinguishes Japanese pop from Western pop. Why the sabi sounds like the sabi and the first-aid kit when it will not lift, the two maximization strategies (exposure and anticipation) and the boredom trade-off that governs them, the internal structure of a chorus and the two ways to build one, the role and the optional nature of the o-sabi, the B-melo as a genuinely Japanese invention, and the transfer table for what survives outside…

Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: Professional agent skills for composing and arranging popular music. The licence is MIT.

When your agent uses it

  • Arranging J-pop
  • Anime-adjacent pop
  • A chorus does not lift
  • Deciding whether to add a bridge

Example prompts

  • “/mc-style-jpop”

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 Style Jpop loads about 1.6k tokens when it runs. Until then it costs about 188 tokens; SKILL.md has 428 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~188
When it runs · the whole SKILL.md, loaded when a task matches
~1.6k

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.

J-pop as a style layer (日式流行风格层) - the chorus-centred design discipline that distinguishes Japanese pop from Western pop. Why the sabi sounds like the sabi and the first-aid kit when it will not lift, the two maximization strategies (exposure and anticipation) and the boredom trade-off that governs them, the internal structure of a chorus and the two ways to build one, the role and the optional nature of the o-sabi, the B-melo as a genuinely Japanese invention, and the transfer table for what survives outside J-pop. Use when writing or arranging J-pop or anime-adjacent pop, when a chorus does not lift, when deciding whether to add a bridge, or when borrowing a J-pop device into another style. 日式流行、Jpop、サビ、副歌、B メロ、大サビ、落ちサビ、动漫歌。

日式流行风格层(J-POP)

J-POP 与欧美流行最根本的差别不在和声,在"整首歌为副歌服务"的程度。

欧美流行:主歌与副歌是两个内容。 J-POP:主歌与 B メロ 是副歌的铺台面(お膳立て)。

这个差别产生了一整套 J-POP 特有的设计纪律,就是这个 skill。

★ 一个提醒:日式作曲法里的通用部分都在通用层(L1 的旋律/和声/曲式,L2 的打ち込み/演唱)。 本 skill 只写"确实是 J-POP 特有"的部分。


1. 动笔前必填

必填问法
① 副歌在哪、长什么样★ 先写副歌。J-POP 是倒推设计的(mc-form §5)
② 副歌要出现几次§5。这是曝光与厌腻的权衡,要主动决定
③ 进副歌前做什么§6。这一处比副歌本身还重要
④ 要不要 C メロ★ §8。默认答案是不要

2. ★ 移植表

手法可搬出 J-POP 吗说明
A–B–サビ 三段构成✅ 可搬,已被华语流行全面采用mc-form §2.2
B メロ(预副歌)✅ ★ 可搬,而且是 J-POP 对世界流行最大的贡献之一它给了"渐强"一个专门的段落
和声语汇(王道/小室/卡农/丸サ)✅ 可搬已在 mc-progressions
落ちサビ(稀薄副歌)✅ 可搬,且极有效它是 mc-arrangement-arch §3 减法的一个具体形态
副歌最大化(曝光策略)⚠️ 半搬★ 欧美流行的副歌重复次数明显更少。搬过去容易显得"啰嗦"
大サビ(C メロ)⚠️ 半搬它对应英美的 bridge,但性格更内省、常带半速感
キメ(插旗句)⚠️ 半搬在摇滚里通用;在慢歌里是 J-POP 味
頭サビ(开场即副歌)✅ 可搬短视频时代反而更通用了
"整首为副歌服务"这个哲学本身❌ ★ 不可搬欧美/独立/爵士的主歌是有独立价值的。照搬会让主歌变成空洞的过场

★ 判据:

可以搬走它的装置(B メロ、落ちサビ、頭サビ), 但不要搬走它的世界观(主歌只是铺垫)。


3. 副歌为什么听起来像副歌

基本原理:サビ = 全曲最高扬的点,也是歌词里最需要传达信息的地方。

3.1 旋律曲线

A 段唱得低 → B 段逐步上行 → サビ 跳到高位并停在那里。

★ 在结构典型的歌里,就算清唱也能听出副歌在哪。

这是一条自检动作:把旋律清唱一遍。听不出副歌在哪,副歌就没写成。

3.2 伴奏跟着曲线走
轴A 段サビ
纵轴(厚度)薄而柔强到不会输给全声的人声,用满从低到高的音域
横轴(时间密度)以四分/八分音符为主加入十六分音符乐句抬高密度
3.3 ★ 一个容易漏的细节

副歌旋律有起有伏时,旋律下行的部分最容易被伴奏埋掉—— 在那些位置故意让伴奏留空隙。

这条对应 mc-texture-layering §3 的深度线索: 旋律下行时它在"高/快"两条线索上都输了,必须靠留白补回来。

3.4 副歌各遍结尾都一样时

各遍编曲和结尾都差不多时,最后一遍会显得"到底了却没有再往上"。藤谷给的做法是把最后一遍拆成前后两半做对比:前半先把热度压下去(乐器减到只剩钢琴或主奏),听众才会把后半重新冲上来的亮点听成"更高"而不是"又来一次";后半配合亮点一次冲上去,旋律可以不完全照谱、带一点即兴(fake)味,弦乐等声部继续往高音域走(藤谷 p0069)。

篇幅够的话,也可以让最后一遍不与前面等长,做成两倍长度,同样是前半安静、后半接近副歌处愈加热闹(藤谷 p0062)。两种做法的共同点是靠"先压下去再顶上去"制造差异,不是单靠反复堆同一个音区。


4. ★ 急救包:"副歌起不来"

按这个顺序试:

#做法注意
1人声上不去 → 叠高音区乐器★ 别埋掉人声:把高音塞进人声的空隙里
2加低音区乐器和节奏型乐器抬密度
3★★ 终极法宝 = "人声"加和声或 aah/ooh/hah 式的合唱——副歌立刻就像副歌了

★★ 人声的能量效率大约是乐器的 3 倍。 乐器费很大劲才能达到的高扬,人声轻松就能做到。

★ 这条是本 skill 最实用的一句。 "副歌不够炸"的第一反应不该是加乐器,是加人声。

冷知识:英文用 "chorus" 指副歌,词源就是最大高潮处大家一起唱。


5. 最大化策略 A:曝光

人对反复听到的东西产生依恋,第一策略是让副歌被听到尽可能多次:

  • 开场用 頭サビ
  • 尽量压缩间奏与平歌
  • 堆 1 サビ、2 サビ、3 サビ、4 サビ
  • 最后一节用 A−B−C−C(−C−C),反复副歌造全曲大高潮
5.1 ★ 但这是一个权衡

"整首都是副歌"会腻—— 流行编曲就是"如何让人尽可能多地听到副歌而不厌烦"这个游戏。 副歌太少记不住,太多则乏味。

防腻装置:

装置做法
同旋律换编制第 3 遍副歌突然变安静 = 落ちサビ;頭サビ 用适合开场的编制(薄伴奏+慢速+自由速度 = 叙述式导入,或原样演奏 = 炫目开场)
转调同编制下靠换调避免单调(→ mc-modulation,★ 但注意它的套路警戒线 §6)

6. ★ 最大化策略 B:期待

进副歌前的那一段最要紧。 与其懒洋洋地滑进副歌,在进入前制造一个变化,抓耳程度高得多。

做法
突然全停(ブレイク),然后"砰"地进副歌
和弦上加一个小转折
简单的八分音符渐强
副歌前的鼓 fill —— 对熟悉这首歌的听众,情绪会随 fill 提前上来

这些的本质都是制造"来るぞ来るぞ"(来了来了)的期待。

6.1 ★ 一条警告

副歌的编曲当然要有吸引力,但如果平歌(主歌)没有同等的吸引力, 听众根本撑不到副歌。

这与 §2 移植表最后一行呼应:"主歌只是铺垫"这个世界观有它的代价。


7. 副歌的内部结构

  • 副歌作为一个乐节,内部高潮仍遵守"2/3–3/4 处"规则
  • ★ 防止竜頭蛇尾(虎头蛇尾):即使副歌开头就在高点, 也要检查后半是否还有充分的高潮、能否实质地收住—— "重复部分动机、再次推起来,不要让它松掉"
7.1 两种做副歌的方式
型说明
口号型建立在短动机重复上(摇滚常见,听一遍就记住)
歌い上げる型(全声唱上去)长旋律——这是日语"サビ"一词的本意(melo = sabi 形),日本流行与抒情曲常见
7.2 适合副歌的动机构成

这两种只是给内部乐句排布贴标签,不是另一套独立技法:怎么把动机重复、推起来、在后半收住,仍然按本节开头"2/3–3/4 处"和"防止竜頭蛇尾"两条来做,曲线的走向见 §3.1。

构成效果
a a b a最后再现,满足感强
a b a ca 抓注意力,c 承担大高潮(c 落在 2/3–3/4 处附近,呼应上面那条规则)
7.3 ★ 落ちサビ 的实战范例

(抒情曲)

第 2 番副歌之后,后半的伴奏做得完全满 → 听众预期第 3 番也会轰进来 → 结果只给一个钢琴 + 人声的耳语式副歌 → 2 或 4 小节后乐队一起轰进来 —— 极其动人。

★ 这是"利用期待再翻盘"(mc-melody §8.2)的教科书实例。


8. ★ 大サビ(C メロ):默认不加

8.1 它是什么
项说明
作用一句"ところで"(话说回来)或"だけど"(可是……)的旁白/另一视角,给歌层次深度
性格常是内省、收敛的旋律;快歌里常把时值拉长,听起来像只有这一段掉进了半速
★ 另一家的说法藤谷(p0060):D 旋律是副歌的衍生型,靠加入若干第一次出现的要素再造一个高潮,这里的气氛不太可能平静。两家并排:一个当另一视角的旁白写,一个当第二高潮写。判据是它后面那个副歌要不要靠对比才有分量,要就走内省,不要就走衍生
手法参考静态的音高运动 + 转调 + 以小三度关系和弦为主的和声
位置★ 它的功能是"主歌",所以后面一定跟一个副歌。情绪平静下来之后,后面那个副歌的高潮才更有分量
8.2 ★ 它不是必须的

大サビ 不是强制的: 仅仅出于习惯加上的大サビ,反而会削弱歌曲的势头。

先确认各节的副歌重复是否真的让人觉得予定調和,再决定加不加。

自检动作:把 C メロ 拿掉听一遍。如果没变差,就别加。


9. 与 ARR-SPEC 的字段对应

字段本 skill
meta.style_layermc-style-jpop
form[]§3、§5;★ 大サビ 的 name 填 Bridge(mc-form §7)
energy_curve§3.1 的曲线:A 低 → B 升 → サビ 高位
subtraction_events★ 落ちサビ 就是一个减法事件(§7.3)
vocal.stacking§4 的第 3 条——加和声/合唱是副歌起不来的首选解
vocal.chorus_variation§5.1 防腻装置(lint #16)

10. 写完后必过

  • 清唱能听出副歌在哪(§3.1)
  • 副歌旋律下行处,伴奏留了空隙
  • 副歌起不来时,先试了加人声而不是加乐器
  • 副歌出现次数是主动决定的,且配了防腻装置
  • 进副歌前那一段做了变化,不是滑进去的
  • 主歌本身有吸引力,不是空洞的铺垫
  • 副歌后半也有高潮,没有虎头蛇尾
  • ★ 加了 C メロ 的话,拿掉听过一遍确认它有用
  • 往别的风格搬时,查过 §2——没有把"主歌只是铺垫"一起搬走
