Soaring Harmonies

I just came from watching a friend perform with his choir. I've been to lots of kinds of concerts, but I think this was my first choral concert. It was a good show; some of the pieces were beautiful and sounded quite difficult, and I, along with a decent portion of the audience, joined them onstage for the Hallelujah Chorus. Here are a few observations for the road:

• I've always been intrigued by how sopranos in particular are able to mostly avoid singing perfectly on key by doing more vibrato than note
• You can tell a choir is well trained if nobody is mouthing the words along with the soloist
• It's a good thing there's the word "hallelujah," because "yay," which means basically the same thing, just doesn't sound as grand when you sing it.
