Sequencing: Score concept, time signatures for non-musicians, Parts as
DAW tracks, arpeggiator/legato/glide context with TB-303 and acid history.
Synths: synthesis philosophy, DX7/Juno/JP-8000 history, practical combos.
Effects: real-music context (The Edge, DJ knobs, shower reverb), why signal
chain order matters, automation as breathing, LFO as repeating automation.
Drums: drums-as-genre foundation, genre group cultural context, fills as
transition signals, drum synthesis as real drum machine techniques.
Playback: three output options context, MIDI as the working musician's path.

NamedChord.acceptable_tones now uses prefer_flats based on circle-of-fifths
conventions. Cm7 shows (C, Eb, G, Bb) instead of (C, D#, G, A#).
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Flat keys now display flats (Bb, Eb, Ab) instead of sharps (A#, D#, G#).
Uses the "no duplicate letter names" rule: if building a scale with
sharps produces two notes with the same letter (e.g. C and C# in C minor),
the scale is rebuilt with flat spellings instead.
- Tone.add() and Tone.from_index() accept prefer_flats parameter
- TonedScale detects flat vs sharp per-scale automatically
- F major: Bb (not A#), Eb major: Ab Bb (not G# A#), etc.
- All tests and docs updated to match
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- scale_diagram() showcased on homepage and quickstart
- New cookbook page: analyze a song, 12-bar blues, find chords in a key,
compare scales, guitar chord chart, explore intervals
- play_progression() for sequencing chord playback with gaps

- Version bump to 0.8.0
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
