As written, the exercise loops these 4 measures; Stone's instruction is 20 repetitions without stopping.

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.

Every stroke alternates — pure singles, so the challenge is evenness of sound and spacing, not sticking memory. Measure one leads right, measure two flips the lead to the left — both hands learn to start the figure. The hands share the work evenly — 15 strokes each per cycle.

Common questions

What tempo should I start №19 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.
What should I listen for in pure singles?: Matched sound between the hands. At any tempo, close your eyes for a rep and check that you cannot hear which hand is playing — that evenness is the entire point of the exercise.
