Why We Should Mark Our Music (In Pencil, Of Course)

Kristin Rosenqvist tipped me off to this video from Tenebrae, regarded as one of the finest choirs in the world (maybe we'll crack the Top 25 in the coaches' poll someday). In the video, two things become apparent: there aren't that many members, and they mark their music. Kristin wonders whether one of the reasons they're so good could be the marking of the music, like Kathy occasionally suggests we do (and by "occasionally," I mean "often"). I reckon it wouldn't make our singing worse!
