If I'm just noodling for ideas, I listen to the radio(WJZW 105.9 FM in the Washington Metro area,....it's jazz). If I have an idea that's fairly solid I always listen to Mozart,.....usually start with "Adagio and Fuge in C minor", then assorted overtures,.....Mussorgsky's "Pictures at an Exhibition" is also good.
