I’ve talked before about subtracting notes in order to make practice easier (https://www.youtube.com/shorts/YH9J0vx-0qg), but you can also do the opposite in some cases!
If you have differing rhythms in both hands, sometimes it’s easier to add notes to start building the muscle memory. Doing this can also keep your other hand (the one with the longer rhythm) engaged, so you don’t feel like you have to rush to the next note. A technique like this can be very useful when practicing intricate Bach passages. Where are some spots you can temporarily 'add' notes to make practice easier?
