Charango Metronome

Give every rest the same attention as every stroke — run a cell against this click until the whole hand quits drifting.

A rasgueo strikes all five courses at once, so unevenness has nowhere to hide the way it might on a single picked string. Start slow enough that down and up feel identical, then raise the tempo only after a full minute passes without the click and the stroke drifting apart.
