test? As mentioned earlier, many musicians already do a version of mixed practice, splitting their sessions between, say, thirty minutes of scales, thirty minutes of reading new music, and thirty minutes of practicing familiar pieces. That’s the right idea. Chopping that time into even smaller pieces, however—of fifteen minutes, or ten—can produce better results. Remember: Interleaving is not just about review but also discriminating between types of problems, moves, or concepts.
