1. Take Lessons/Practice
Pausing any new skill that requires practice may result in slipping backwards and having to review or repeat past lessons. Continuing to take lessons is the most effective way to retain old and current skills as well as to build new ones. If you can’t find a teacher in person, online lessons are also great. If you can't do online lessons either, gently practice on your own and follow the instructions in your notes.
2. Watch Your Videos
Video clips that you have recorded of yourself should be kept in a folder where you can watch and review all of the pieces that you’ve learned to play. Imagine playing along as you listen. When you’re unable to take lessons or practice much, the videos will help to boost your memory.
3. Read Your Music
Reading music away from your instrument is a great way to retain information regarding the notes and dynamics. Students who visit repertoire or music books outside of the lesson develop a heightened sense of awareness regarding notation, patterns, hidden melodies, or other musical gems.
