It Came Upon The Midnight Clear

Some of the many, many lines of music we sang, ages ago.
We very often sang different voices, with different scores. This photo somehow displays how chaotic it sometimes was.
We once had a concert in a church. Before the concert we sought the best place to stand. The acoustics were so weird, we couldn't even hear the person immediately next to us. So instead of the optical best position, we had to put ourselves in a boring position. The audience will not have noticed, they came for the music, not the men and boys in their robes.
Thanks to Ingeborg for hosting the Abstract Thursday challenge.
