Random chunks, on rotation.

Drop a score in PDF or MIDI form. We slice it into measure-chunks, then put one on screen at random, one at a time, until every chunk has had its turn. Then we reshuffle and start again.

Why random? Interleaved practice, jumping between unfamiliar fragments instead of drilling them in order, makes recall harder in the moment, and that struggle is what consolidates the music into long-term memory. A piece you can play start to finish isn't truly learned until you can also play it from any measure. The approach is drawn from Learn Faster, Perform Better. Same principles, applied to the page in front of you.
