Come on out, you bathroom singers
Take the hymn book and sing along. Understand the words you are singing. Don’t worry if you have no talent for singing; most people don’t. The ones who do are usually in the choir. Can you imagine how bored you would be if you went to a concert and didn’t know any of the songs? Exactly! Taking part in the proceedings, even if you don’t get much out of it initially, goes a long way. Don’t expect quick results.
