01和弦地圖Chord map
每點一個和弦，看 Jacob 用哪些 voicing 類型。點擊播放和弦聲音、跳原影片。Each dot is one chord — see which voicing types Jacob reaches for. Click to play the chord and jump to the source video.
02和弦轉換 A→BChord transitions A→B
每點是一次相鄰和弦轉換。看 Jacob 怎麼從一個和弦走到下一個。點擊依序播放兩個和弦、跳原影片。Each dot is one adjacent chord transition — see how Jacob moves from one chord to the next. Click to hear both chords in sequence and jump to the source video.
03樂句進行Phrase progressions
每點是一個樂句（多個和弦）。內建 A→B 樂句查找與「打字輸入和弦進行」的 kNN 搜尋（符號層級近似），命中後地圖自動 zoom-in。Each dot is a phrase (multiple chords). Includes A→B phrase lookup and a "type a chord progression" kNN search (symbol-level similarity); the map auto-zooms to the hit.
04終止式瀏覽器Cadence browser
依類型（ii–V–I、V–I、backdoor、plagal…）瀏覽 761 個終止式。含五線譜鍵盤動畫與影片跳轉。Browse 761 cadences by type (ii–V–I, V–I, backdoor, plagal…). With staff and keyboard animation plus video jump.
05Reharm 瀏覽器Reharm browser
瀏覽偵測到的再和聲手法（tritone sub、borrowed chord、mode mixture…）。按歌曲或手法類型篩選。Browse detected reharmonization devices (tritone sub, borrowed chord, mode mixture…). Filter by song or device type.
06轉調時間軸Modulation timeline
逐首顯示 local key 的段落色帶，一眼看出調性重心轉移的時機與頻率。Per-song color bands of local key — see at a glance when and how often the tonal center shifts.

07Voicing Generator
輸入旋律音（space-separated，例如 G4 C5 E5 G5）+ Key，點 Generate，自動從 Jacob 的編曲中撈出最接近的 voicing 並用 beam-search 做 voice-leading smoothing；播放時同步顯示五線譜與鋼琴。Enter melody notes (space-separated, e.g. G4 C5 E5 G5) plus Key, click Generate. It retrieves the closest voicings from Jacob's arrangements and smooths voice leading via beam search; playback syncs with staff and piano.
08Voicing Tiler
輸入旋律，用整段真實的 Jacob「手勢」（2–4 和弦的樂句 chunk）鋪砌成編曲：樂句檢索 + DTW 骨架計畫 + segmental DP。每個和弦附五線譜，可線上播放。Enter a melody and tile it with real Jacob "gestures" (2–4-chord phrase chunks): phrase retrieval + DTW skeleton planning + segmental DP. Every chord comes with a staff and is playable inline.
09Harmonizer
自由唱一段單音 melody，系統用 YIN + Viterbi DP 反推和弦，再以 phase vocoder 把人聲 pitch-shift 到其他聲部、Just Intonation 對拍，整段和聲跟著你 microtone 走。Sing a free monophonic melody. The system back-infers chords with YIN + Viterbi DP, then pitch-shifts your voice to other parts via phase vocoder and locks them to Just Intonation — the harmony follows your microtones.

關於資料About the data資料來源與限制Sources and limitations
注意：OMR 對 Jacob 的密集音叢有判讀誤差，特徵值會帶有這層雜訊；影片對齊誤差約 ±2–5 秒。屬探索用途，細節見
RUNLOG.md。How the data was built: Scores from 78 Jacob Collier arrangements (PDFs plus June Lee's transcription videos) were converted to MusicXML via Audiveris OMR. music21 then sliced each chord into ~26 features (pitch, register, function, voice leading, time), with weighted similarity → UMAP 2D → HDBSCAN auto-clustering. 4 songs (moon_river / danny_boy / christmas_song / flintstones) have their chords aligned to the source video.
Note: OMR misreads Jacob's dense clusters, so feature values carry that noise; video alignment error is roughly ±2–5 s. Exploratory use only — see
RUNLOG.md for details.
