Three new export methods on Score:
- to_lilypond() — complete LilyPond source files for PDF engraving
- to_musicxml() — MusicXML 4.0 for MuseScore/Sibelius/Finale
- to_tab() — ASCII guitar/bass tablature (also on Part)
All three handle multi-part scores, bass clef detection, tied notes
across barlines, chords, and drum tone filtering.

Five new synth waveforms: tape-replay Mellotron (strings/flute/choir
tapes with wow, flutter, saturation, 8s fadeout), hard sync oscillator,
ring modulation, wavefolding, and analog drift VCO with pitch
instability. 14 new instrument presets for Score.part(). Synth kwargs
now pass through play()/save()/_render(). 808 bass envelope fixed
from pluck to piano.

Two variants modeling Himalayan singing bowl acoustics:
- Strike: mallet hit with chirp from inharmonic partials, long ring
- Ring: rim-rubbed sustained tone with slow build and beating modes
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Wurlitzer: reed-based, nasal, biting — bark on hard hits
- Vibraphone: aluminum bars with motor tremolo (spinning disc)
- Pipe organ: multi-rank (8'+4'+2'), constant air, wind chiff
- Choir: formant-filtered glottal source, vowel control via lyric=,
no vibrato (ensemble handles voice variation)
- All four with instrument presets, audio demos, and docs

Tine + tonebar + electromagnetic pickup model with bell-like
harmonics, metallic attack transient, and pickup nonlinearity.
electric_piano instrument preset now uses rhodes_synth instead of FM.
FM section updated to show bells. Audio demos for both.

Basic waveforms now play without envelope shaping so you hear
the raw timbre. Complete Example bass at 1200 instead of 600.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Every synth section in the docs now has an audio player.
Classic waveforms, FM, supersaw, and all 31 instrument synths
each play a C major arpeggio for easy comparison.

Both pages now show the same rock beat example in G major with
piano, saw lead, triangle bass. Code and audio are in sync.

The pad envelope has slow attack — wrong for fast acid lines.
Updated both the docs code and the audio generator.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Complete Example now uses rock beat with piano/saw/bass in G major.
Added audio player for the arpeggiator code example.

28 audio samples total. Tabla (teental, keherwa, chakradar at fast
tempos), dhol, dholak, mridangam, metal blast, cajón. No labels
on stacked players.

20 WAV files covering quickstart, sequencing, drums, playback,
and cookbook examples. Audio players embedded after every code
block that calls play_score().
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- docs/generate_audio.py renders 12 code examples as WAV files
- Audio players embedded in sequencing and drums docs via raw HTML
- Covers: piano hold, articulations, dynamics, filter ramp, rock,
bossa nova, djembe, tabla, marching snare, ensemble, strum, swell
- WAV files gitignored — generated at build time

- Drums are real Parts with full effects pipeline
- split=True creates kick/snare/hats/toms/cymbals/percussion Parts
- Sidechain triggers on kick only
- Score.from_midi() imports Standard MIDI Files
- Document split drums workflow

Load any Standard MIDI File into a Score. Zero-dependency parser
handles Type 0 and Type 1 files. Each channel becomes a Part,
channel 10 becomes drum hits. Roundtrip with save_midi works.

Every page now ends on prose instead of a code block.
Chords, tones, scales, effects, drums, CLI, cookbook,
fretboard, playback, systems, theory — each with a
sentence that ties the page together.

- Chord.figured_bass: classical inversion notation (6, 6/4, 7, 6/5, 4/3, 2)
- Chord.analyze_figured(): Roman numerals with figured bass (V6/5, ii6)
- Chord.pitch_classes, normal_form, prime_form, forte_number: set theory
- Scale.recommend(): ranked scale suggestions from note sets
- Forte catalog: all trichords and tetrachords
- Documented in chords and scales guides
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Covers the prompt, theory commands, composition flow, effects,
automation, LFOs, playback, export, and a full start-to-finish session.

Systems: fix "four" to "six", add cultural context for each system
(Indian ragas, Arabic maqam, Japanese koto, Blues Delta origins,
Gamelan's influence on Debussy). Each system feels alive now.
Fretboard: add scale_diagram chord highlighting, non-string instruments note.
Theory: warmer opening, cross-reference to composition guide.
Tones, scales, chords, cli: verified complete — no changes needed.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Two clear paths: theory (no audio needed) and composition.
Theory section expanded with tones, intervals, keys, chords,
analysis, modulation, 6 systems, guitar — all pure Python.

Quickstart: zero to arrangement in 5 minutes, pytheory demo, MIDI export.
CLI: add demo command docs at the top.
Cookbook: acid house, dub reggae, jazz ballad, song sections, MIDI export recipes.
