Here is some old science for you, so I'm not sure how valid it is (wild claims are always made).

It suggests a connection from the cerebellum to the parietal lobe and states that this regards processing of pitch. Maybe there's gross function there, but some of these sub processes being inhibited don't allow for "fine" function. It'd be interesting to see if this grasp of pitch could be linked to imaginative thinking while listening to music.
