My teenage son will never cease to amaze me.  It seems that he is able to do just about anything he puts mind to.  He plays all kinds of sports very well and has a great deal of musical talent.  However, he is unable to sing and never tries to improve his voice.  He has spent a lot of time taking lessons and has turned out to be a very accomplished guitarist.  We have a lot of fun around our house when he pulls out his guitar.  Recently, he has decided he wants to learn to how to play blues guitar.  I am sure he will do as good with this as he does with everything else.
