yes, and also to practice intros - not too long & solely info which isn't in the song! taping is a very good idea, if revealing sometimes. The harmony workshops at festivals are a good way in. Many clubs seem now to be fuller of potential singers than listeners, and all are anxious for their turn. Offering constructive advice is much better than turning them away, I feel: just as some stand-up comedians find eventually that they prefer to hear others rather than perform, the truly tone-deaf tend quietly to participate by applauding and putting money in the hat!
