Firstly I would suggest try practicing with no music. You'll learn a LOT about yourself.

Secondly, the journey of trawling your own music collection for tracks that inspire each rhythm in you is a rich and rewarding one. It's a deep meditation in itself.

Thirdly, Gabrielle has produced a lot of great music for this purpose. You can get it by mail order from Amazon, or Gabrielle's website, or you can download it from iTunes. Enjoy!
