Deep Listening
Listening to music with musicians is interesting. Most musicians I know think of listening to music as an activity you do exclusively; not while reading a book, not while looking at your phone, or while working on email. The music deserves full attention while it’s playing. You learn and gain from the music by listening attentively and deeply. This isn’t to say that musicians don’t like background music. They do, but they also have the annoying habit of actually listening to the background music much more than normal people do.
