Christian worship usually, but not always, includes an element of music. There are traditions within Christianity that are opposed to music in worship, but they are the exception. Musical styles in worship can range from Gregorian chant to Gospel. Generally speaking, Episcopalians are musical traditionalists, and like organ music and a big, robe-wearing choir. But that is changing in some places, and you will find Episcopal churches that feature more contemporary music of various kinds.
Whatever the style of music involved, church is one of the few places where grownups still get together and sing. I think it’s awfully good for us to let down our guard and let loose on a beloved hymn, not worrying about whether we’re “good” singers or not. Those who sing pray twice, as St. Augustine supposedly said…
Which brings me to the connection I wanted to make to prayer. I think praying is another thing that we do quite naturally when we’re young, but as we grow older we tend to become intimidated and inhibited about it, until we might let it drop out of their lives completely. I wonder if it’s not pretty common to put the same expectations on ourselves about singing and praying: if we’re not good at it, we should just leave it to the professionals. Which leads to a pretty impoverished sort of way to live, unfortunately.
