Sources & editorial method
来源与编辑方法

This is a curated listening and composition reference, not a claim that every tradition can be reduced to Western theory. Mathematical checks, scholarly sources, listening interpretations and constructed examples serve different purposes.

本站是聆听与创作的参考资料，不主张把所有传统化约为西方乐理。数学检查、学术来源、听感解读与构造示例各有用途，不能互相代替。

How to read the examples · 如何使用示例

• Scale playback demonstrates the stored interval model. Microtonal intonation, ornament, melodic development and tuning vary with tradition and performance. Equal stored intervals do not establish historical or musical equivalence.音阶试听展示存储的音程模型。微分音音准、装饰、旋律展开与律制会依传统和演奏变化。存储音程相同不等于历史或音乐意义相同。
• Chord loops, generated phrases and drum grids are teaching sketches unless explicitly identified as transcriptions. A song may illustrate a feature in only one passage; a whole recording is not proof of a single scale, chord progression or production method.除非明确标为扒谱，和弦循环、生成乐句与鼓点网格均是教学示意。一首歌可能仅在某个段落展示某种特征；整首录音不能证明唯一的音阶、和弦进行或制作方法。
• Genre boundaries, emotional descriptions and production suggestions are editorial interpretations. Tempo ranges, mix settings, timbre scores and acoustic thresholds are guides, not universal rules or measured properties of every example.流派边界、情绪描述与制作建议属于编辑解读。速度范围、混音参数、音色评分与声学阈值是参考，不是普遍规则，也不是对每个示例的实测结果。
• Vocal ratings, ranges and passaggio estimates are not clinical measurements. Commercial recordings alone do not establish vocal-fold anatomy, pressure, health or unamplified projection. Unsupported anatomical explanations have been withheld.人声评分、音域与换声位置估计并非临床测量。仅凭商业录音不能确定声带结构、压力、健康状况或未扩声的投射力。缺乏依据的生理解释已撤下。
• YouTube availability is controlled by YouTube and the video owner, and may differ by region, age or account. A working watch link does not imply permission to embed. Player errors are reported per video; an unavailable clip does not disable the others.YouTube 与视频发布者控制播放权限，且权限可能因地区、年龄或账户而异。观看链接可用不代表允许内嵌播放。错误按视频单独处理，不会因一条视频受限而关闭其他视频。
