time signature = 12 beats per measure
tempo = 370 beats per minute
Rhythm cycle. This cycle has a length of 12 beats (one measure) and is repeated through most of the piece.
Rhythm cycle patterns (for abcdrums)
Polyrhythm. The rhythm cycle contains the polyrhythm 2 against 3, which is found in the low bongo and low tom parts.
Solo pattern. The composition is based on this pattern. It is played by two drums, and has a duration of two measures = 24 beats.
Here is the same pattern in abcdrums notation.
C: dzzzdzzzdzzd zdzddzzzzzdd
E: zzdzzzzdzzzz dzzzzzdzdzzz
Note: This pattern is usually played in the form CCEC or EECE.
Intro pattern. The introduction to the composition is an arithmetic series based on this pattern.
The length of pattern A is 4 and there are 10 A's, for a length of 40. The pattern would be played
A zg AA zg AAA zg AAAA
where g is the length of the gap between patterns. To find the length of the gaps, we solve the equation 40 + 3*g = 1 (mod 12). The smallest value of g that makes this equation true is 3, since 40 + 3*3 = 49 = 1 (mod 12). Therefore, the duration of the series
A z3 AA z3 AAA z3 AAAA has length = 1 (mod 12)
As required, this pattern starts and ends at the beginning of a measure.
Tihai ending pattern. The tihai is based on this pattern.
This pattern has length 13. To find the gap length g, we solve the equation 3*13 + 2*g = 1 (mod 12). The smallest value of g that makes this equation true is 5, since 3*13 + 2*5 = 49 = 1 (mod 12).
So F z5 F z5 F has duration = 1 (mod 12).
Melody. There are two melodic patterns, which can be played together or singly. Each pattern has length 4 measures or 48 beats.
G: C3 D3 E6 F2 F2 F2 G6 C3 D3 E6 F2
F2 F2 E6
H: G,3 A,3 C6 D3 D3 E6 G,3 A,3 C6 D3 D3 C6
