During my college years took a course in Music Listening.
Had to learn to tell the keys, notes, etc. apart. While cannot do it today, the effort to pay attention has stayed with me and made listening more eventful and enjoyable. There are probably home study courses that would do the same. Once the ear is trained it does not easily forget.Being able to tell why something sounds good or is missing something might be a little hazy but being aware of it is crystal clear.
