I've been playing mostly lead guitar for too friggin long now, and in all the bands I was in I'd do very minimal harmonies on backup vocals. COuple of years ago I started on more Acoustic style songs as well as the electric, and I find myself wanting to carry a tune not just with my guitar playing, but vocally as well. So basically I want to learn to play and sing at the same time. Right now when I sing a tune I keep the vocals so low I can barely hear myself try to sing over the guitar. It's like when I first started on guitar and didn't feel adept enough to comfortably play loud. Any hints, tips, ideas, or recommendations from the many people who already have this skill under wraps and "are not afraid of their voice"?
