Music Studio

Music theory helper: name a chord from notes, guess the key, get a progression, or list what fits a key. Returns both the ABC chord-symbol spelling (for play-sheet-music) and the Strudel form (for play-live-pattern). Tasks: detect-chord (notes -> chord name + what to play next), detect-key (notes or chords -> best key + diatonic chords), suggest-progression (key [+ romanNumerals] -> chord symbols), scale-for-chord (chords -> the scale to improvise over each), key-chords (key -> every diatonic triad, seventh, and chord scale). Use it before writing chord symbols for a style preset, or to check a harmonization.

Turn an ABC melody into Strudel mini-notation so a scored piece can be remixed live. Returns runnable code — setcps() from the Q: tempo, one [...] bar group per bar inside note("<...>"), with a chord("<...>").voicing() layer stacked alongside it when the ABC has chord symbols (one stack(), because Strudel plays only the last expression) — then pass it to play-live-pattern. Durations become @ weights, rests become ~, triplets nest, the key signature is folded into the note names, and %%MIDI program picks the sound. Lists what was lost (grace notes, dynamics, repeats, lyrics, other voices, inline tempo changes, a short final bar, ABC's own gchord/drum accompaniment). Pick a single voice with `voice`; re-run per voice and stack() them for a full arrangement.

Returns detailed reference material for music composition. Topics: instruments (GM instrument list + combos), drums (patterns + percussion notes), abc-syntax (notation reference), arrangements (multi-voice patterns), genres (complete ABC templates for jazz/blues/folk/rock/bossa/classical), styles (what each style preset does), midi-directives (%%MIDI reference).

Reference material for Strudel live coding (performance mode). Topics: mini-notation (pattern syntax), sounds (synths, 71 drum banks, 128 GM instruments, 128 vcsl orchestral/percussion samples), effects (filters, reverb, delay, FM synthesis, envelopes), patterns (transformations, probability, euclidean, arrangement), genres (complete templates: techno/house/dnb/ambient/jazz/lofi/synthwave), tips (tempo, common mistakes, ABC↔Strudel crossover), visuals (pianoroll/scope draw methods, the visuals presets and the theme parameter), hydra (WebGL shader backgrounds: initHydra, H(pattern), the audio-reactive a.fft object, recipes, cheat-sheet), advanced (sample loading, wavetables, ZZFX, continuous signals, chord voicings).

Live-code music patterns using TidalCycles mini-notation in JavaScript. Layer drums, synths, and bass with stack(). Choose from 71 drum machine banks, 128 GM instruments, built-in synths, and a full effects chain. Patterns play in a REPL the user can edit directly. Add .pianoroll() to a pattern to show a live piano-roll animation in the widget (or .punchcard()/.scope()/.spectrum() — one draw method per pattern). For a custom animated background, start the code with `await initHydra()` and write Hydra shader code — H(pattern) locks it to the sequence, and `() => a.fft[0]` makes it react to the audio itself (Strudel's output, not the mic); see get-strudel-guide topic 'hydra'. Rather not hand-write one? `visuals` picks a ready-made animation for code that has none (pianoroll/punchcard/scope/spectrum, or hydra-kaleid/pulse/wash/feed). `theme` sets the code-editor colour scheme, which also tints the visuals — match it to the mood (teletext chiptune, sonicPink synthwave, nord ambient, gruvboxDark lofi). Each call creates a NEW player rather than updating the last one — for a tweak, send the whole revised pattern and ask the user to stop the previous one. Use get-strudel-guide for genre templates, sound references, and advanced features like arrangement and sample loading. The Strudel REPL renders inline with an editable code editor, visualizations, and playback controls.

Compose and play sheet music with visual notation, multi-instrument audio, and style presets. Write ABC notation for melodies, arrangements, harmonized pieces, or well-known tunes. Add a style (rock, jazz, bossa, waltz, folk...) for automatic drums, bass, and chord accompaniment. Returns a parse-status confirmation and renders the player; it does not return raw audio. Use get-music-guide for genre templates, instrument lists, and ABC syntax reference. The music player renders inline with interactive playback controls.

Search detailed documentation for Strudel live coding or ABC/ABCJS notation. Returns relevant code examples and explanations from the official docs. Use this when the curated guides (get-strudel-guide, get-music-guide) don't cover what you need — for specific functions, advanced techniques, or when you're unsure about syntax. Powered by semantic search over strudel.cc and ABCJS docs.
