Translate Music Theory Terms for Non-Musicians

You play by ear or you are just picking up notation, and theory talk goes straight past you. This translates the common terms, chord progression, time signature, intervals, dynamics and the rest, into plain language with a listening tip for each, so you can hear what the words mean rather than just read them.
