There is a great computer program, for PC and MAC, called "TRANSCRIBE!." It can be found onine and can be downloaded. There is a free trial period with it, If you try it and like it you can pay for it and they send you the registration numbers. The program takes recordings and slows them down to as much as 5% of the original tempo without changing the pitches. It makes it easier to hear all of the notes as they fly by.
