bayan pitch bends, tihai, dramatic silence, slam finish. Taj Mahal
reverb throughout.

Gamelan uses its own tone names (nem, pi, barang, etc.), not Western
note names. Fixed tonic from C4 to nem4 and added pelog nem/barang
modes. Replaced miyako-bushi with iwato and kumoi (actual scale names
in the system). Added ValueError to exception handling.

New features:
- Chord.from_name("Am7") — build chords from chart names
- Chord.__str__() — prints "C major" instead of raw tones
- Interval constants: Interval.PERFECT_FIFTH, MAJOR_THIRD, OCTAVE, etc.
- PROGRESSIONS dict: 8 common progressions as Roman numeral tuples
("I-V-vi-IV", "ii-V-I", "12-bar blues", etc.)
- Tone.enharmonic: C# → "Db", natural notes → None
- Key.__str__(): "C major"
Fix: docs CI now installs all dependencies (uv sync --group docs)
so autodoc can import pytheory modules. API reference pages were
blank on GitHub Pages because pytuning/scipy weren't installed.
New example: examples/explore.py — comprehensive demo of the full API.
393 tests.
