Aaron talks about the importance of active listening in learning to play any kind of music. He differentiates between passive listening (while you’re making dinner, driving to work, etc.) and active listening, where all you’re doing is listening. He recommends that you make listening part of your practice routine, and that when you listen to something, you think about what you like about the music and what you don’t like. This can then give you ideas for learning. For example, if you like a particular phrase in someone’s solo, you can sit down and learn that phrase, and then try to figure out what about the phrase is pleasing to you.
