expert · LCM = 14
Two against seven — the 2-layer feels like an anchor while 7 swirls around it.
Pattern — 14 subdivisions per cycle
Mute one layer to focus on the other. LCM = 14 subdivisions per cycle.
About 2:7
2:7 has an LCM of 14. The two evenly-spaced notes of the 2-layer create a stable anchor, while the 7-layer subdivides the space into rapid, uneven pulses. The interaction sounds like a single drone with an off-kilter overlay.
LCM of 2 and 7 is 14 subdivisions per cycle.
