Chakra: uke opening, 808 sub throughout, more space, lower register

Browse Source 
- Ukulele opens with gentle fingerpicking, fades after sacral
- 808 sub bass drone follows root of each section throughout
- Tambura enters bar 3, giving uke breathing room
- Harmonium dropped octave with rests between chords
- Singing bowl strikes every 4 bars (was 2)
- Rhodes dropped octave, sparser
- Equal temperament at 432 Hz
