advanced · LCM = 10
Two against five — dreamlike, uneven. The cycle is ten subdivisions.
Pattern — 10 subdivisions per cycle
Mute one layer to focus on the other. LCM = 10 subdivisions per cycle.
About 2:5
2:5 places two notes evenly against five. The LCM is 10, giving 7 total attack points. The 2-layer is far more spread out than the 5-layer, creating a floating, hazy feel. The interaction sounds like the 5 has a slight echo or shadow behind it.
LCM of 2 and 5 is 10 subdivisions per cycle.
