Green tea starts as a fairly traditional composition for Shakuhachi and Taiko drum samples but played in the Korean manner. Two flutists/two drummers. At :51 they go out of phase in tempo and tuning.

At 1:17 it jumps to a probable resonant frequency of 2:1 so Ive compressed the octave into the range of a tritone/#4/b5 (C-Gb). The drum rhythm has also doubled. In the last section the octave has been compressed into a single semitone but its a multi-octave melody so thats why it sounds like its alternating between more than one note
