Goes from C to Eb Then back to C. C is the hardest key for me to play in so It sounds off and I mess up a few times. However it felt great to try a different key I'm not used too. Thanks for the request@alvaromorenoacosta1518 ! I basically just transposed one of my waltzes, so it's not completely new material, But A waltz from C to E is what you wanted so I just recycled. hope that's ok!
