As always, I strongly suggest listening to this track before watching my music theory analysis video (if you are not already familiar with it).
For your convenience, I have pulled the sheet music, chord charts, and any other especially salient diagrams from the analysis and posted them below.
1: The Main Pattern (1/3) 4 instruments, 2 measures, repeated for over 8 minutes.
2: The Main Pattern (2/3) Staggered repeated pattern - 8 notes with 3 combinations of pitch and duration.
3: The Main Pattern (3/3) Time symmetry of main pattern.
4: The Plain Hunt (1/2) Interlocking 16th notes - an expression of the 'plain hunt' change ringing pattern.
5: The Plain Hunt (2/2) Tying pitch to duration creates a 2 beat cycle of pitches in each instrument - contrast with traditional change ringing.
6: The Drums (1/6) First pattern - double tresillo with alternating pattern of unequal 'pulses and gaps'.
7: The Drums (2/6) Second pattern - adding snares in every other 'gap' creates something akin to a polymeter (an isorhythm?).
8: The Drums (3/6) Second pattern - not-quite-even alignment of snares with double tresillo pattern.
9: The Drums (4/6) Third pattern - adding toms to the remaining gaps.
10: The Drums (5/6) Alignment of snare/tom in larger gaps in order to create 2-beat overall rhythmic pattern.
11: The Drums (6/6) Alignment of pitch tresillo with the drums' underlying double tresillo.
12: The Chord (1/2) Just intonation frequency ratios used in the main pattern's constituent chord.
13: The Chord (2/2) Conversion of note duration to note 'frequency' - and equivalence to the relative frequencies of these notes' pitches.
