Hello Bill. I've been finding some really good melodies inside my head. But every time I touches instruments, it doesn't work. How do I let thing in my head out to my hands?  Or, can I just touch non-instruments?
the more you use the instruments, the more accurately they will repressent what you imagined. Think of how much experience you have with talking and writing the english language. i bet you were able to phrase your question exactly the way you had imagined it..... how did you learn to do this? i promise music works the exact same way
