I recently joined a 3 piece band, starring a female lead guitarist/vocalist. They play both originals and cover songs. We have our first gig coming up soon. Recently she's asked me if I would be able to sing back up vocals. I am self conscience about singing. I don't feel that I have a "natural talent", it's something that requires alot of focus an effort to get anything that sounds decent. I have no experience singing live (besides drunken karaoke/open mic...lol). She gave me 3 songs she wants backup vocals/harmonies on. 2 are her originals, 1 is Sunday Morning by No Doubt. I'm having a hard time because these female voices sing pretty damn high (at times) and if i try to sing lower i feel like it just sounds like im talking, and i cant project as well. I told her I would try singing, but Im having some anxiety about it now because I dont wanna sound like ****. Im worried if I dont sing ill be kicked from the band. I would understand though, being in a trio i need to "pull my own weight". Anyone have any good advice for me? I would appreciate it.
