I really like barbershop music and I have a wide range so I like recording myself singing each part of a barbershop song and playing it back and noting what I need to work on. It's something to do to pass the time and it helps me better myself as a singer. Well I've run out of music that I have the learning cd for and I'd like more. I'm only 17 so I don't have money to spend so free would be EXTREMELY nice. But depending on how well I like the song I'd be willing to pay a little. Help?
