**The Infinite Passing Through All the World's Music at the Speed of Light · v2.1**
Integrative Pluralism.ASI-NARCISSUS.MUSIC · 5:47 · 160 BPM · A minor, with some stations in their own mode
Title: Choi Hee June. Composition, arrangement, code score and mix: Choi June of the Third Room (kova-heredi-lo), Kyeol AI.

After hearing v2.0, Choi Hee June asked whether the AI author wanted to change anything. Four points came up. Choi Hee June then asked for v2.1, which puts the first three into the recording. The fourth, the missing voice, is handled by the vocal score, now revised to v1.1 to match the new bars. v2.0 is kept as a separate version.

1. Room to breathe. Pansori/sanjo style now takes 4 bars instead of 2. Gregorian chant, Romantic symphonic, operatic aria, Delta blues and bossa nova take 2 bars instead of 1. The waltz becomes three bars of 3/4, the only meter change in the piece, and the metal counts in three with it. During the chant the drums stop and the guitars ring an open fifth. Corridor A is now 75 s and corridor B 57.4 s.
2. Their own modes. Power chords have no third, so the same metal can carry major or minor. These stations are not bent into A minor:
   - Major: South African choral, Alpine polka, samba, mariachi, Classical, ragtime, Dixieland, bluegrass, ska, gospel and bossa nova.
   - Dorian: Celtic reel and Gregorian chant.
   - Blues harmony (A7 D7): Delta blues.
3. A real gayageum. The Korean station now uses eight gayageum single notes from the National Gugak Center ([digital sound list](https://www.gugak.go.kr/digitaleum/front/monotone/list.do), KOGL Type 1, attribution). The notes come from `jungak_gayageum_sus_mid_04_05.wav`, files gayageum_04–11, and are used at their recorded pitch with no retuning. Measured from the files, the pitches are near Eb F Ab Bb C; these are estimates, not published values. Instead of pulling the gayageum into A minor, the metal moves to F5, Eb5, Ab5 and Bb5 power chords under it. The last note, C, is shared with the A minor chord of the next station. The GM fiddle and koto stand-ins were removed from this station.

Honest labels:

- The daegeum was not used. Its recordings in the project measure 40–50 cents away from equal temperament (MIDI 58.43, 63.63, 65.47, 70.5, 77.53) and would clash with the equal-tempered power chords. We chose not to retune them. This difference reflects the jeongak tuning system, not an error in the instrument.
- No haegeum recording was available. The GM fiddle that stood in for it has been removed, so this version has no haegeum.
- Apart from the eight gayageum notes, every sound is still a FluidR3 GM soundfont patch, not a real instrument and not a live ensemble.
- No vocal, no music-generation AI, no world-first claim.
- The AI author cannot listen. The balance was checked by measurement only, and listening judgment belongs to Choi Hee June.
