Subdivision divides one steady beat into equal internal pulses. Keep the quarter-note BPM unchanged so the exercise trains placement rather than speed.
Two pulses: eighth notes
Count the accented beat as 1 and the midpoint as “and”. At 60 BPM the two clicks are 500 ms apart, but the musical tempo remains 60 quarter-note beats per minute.
Three pulses: eighth-note triplets
Place three equal clicks inside the same beat. Do not squeeze two straight pulses plus a late third; every interval must be equal.
Four pulses: sixteenth notes
Use the louder first click to anchor each group of four. Start slowly enough that all four notes stay relaxed and equally spaced.
Seven and eight: advanced internal grids
Seven divides the beat into an odd septuplet grid; eight creates eight equal thirty-second-note positions. Begin at a low BPM, keep one movement on each accent, and judge even spacing rather than raw speed.
Change grids only at a beat boundary
Ascending, descending, up-down, and random modes hold each grid for the selected number of quarter-note beats. The loud accent stays at the same BPM while the quieter internal clicks change, so the exercise tests rhythmic placement without a tempo ramp.
