Short Roll Progressions and Triplets №20

What this trains

The measure mixes duple and triplet beats — let stage 1's per-note clicks teach the shift before dropping to the beat.

Singles and doubles interleave, so the sticking has to be read, not assumed — the double is where the time usually bends. The right hand leads throughout; pair this exercise with its mirrored neighbor to balance the lead. The hands share the work evenly — 15 strokes each per cycle.

Common questions

What tempo should I start №20 at?

Start at 55 BPM with a click on every note (stage 1). Stone gives no metronome marks — the working convention for Short Roll Progressions and Triplets is to build from 55 toward 110 BPM before moving on, raising the tempo only after a clean 20-rep run.

How many times should I repeat it?

Stone's instruction is explicit: play each rhythm 20 times without stopping, then go on to the next. The app counts the 20 for you and stops the run automatically.

Why does the pattern speed up when I play it?

Almost always the doubles: the second stroke of a pair tends to rebound early. Stage 1's tick on every note exposes the rush immediately — slow down until the doubles sit exactly on the clicks.
