Haha… If they want you to “follow the piano,” they might as well just give you the piano score so that you could properly transcribe for the harp. I concur with Sylvia, please tell us more.
They have rotating priests, but I guess if you do essentially the same service music 3x a Sunday and once on Saturday, week in and week out, you get used to it.
David, this is a fantastic summary. Praise teams DO have their own secret code. I think it is fostered largely by the inability to read music or play without a capo. Glad you made it through.
