I want to learn how to play an instrument but I have no idea where to start. I live in a pretty small town and we do not have any local music shops. I am thinking about taking lessons online or buying a DVD that can teach me. I would like to eventually play the worship guitar. My church is really small and our worship group does not have anything other than a keyboard. I would really like to learn how to play the guitar so that I can be a blessing and worship God along side them. My singing voice is horrible!
