Tonal music revolves around a single tonal centre - most "classical" music. Bitonal superimposes one key on another and has become increasingly widely used in post-bop jazz improvisation. Polytonal just extends this to more than 2 tonal centres.
I started asking myself why Keith Jarrett is a more interesting improvisor than Bill Evans, whose improvisations can be more bland as a whole. Both exquisite craftsmen but polytonal has more spice to the dish. As a fan of Stravinsky I really enjoyed this YT analysis of how he constructed his harmonies by superimposing one key on another. Once you tune into this it kind of hooks you.
