Playing from memory is a very particular technique, not to be confused with playing on automatic pilot. It is vitally important that you are aware of the difference and don’t slip into the habit of not looking at the music merely because you can play on reflex. Mere repetition doesn’t create perfect performance from memory and should be avoided at all costs. Make sure you keep looking at the music, unless you are especially memorising music, otherwise you end up guessing and practicing in mistakes.
