While in rehearsal

Part of last night’s choir rehearsal was spent with a very enjoyable arrangement of How Can I Keep From Singing?  The next anthem we rehearsed was a fairly ambitious arrangement of  Lasst uns erfreuen (and, also, nicely done).  There is a descant for verse 2, the sopranos have a line unlike the tune (and the meter is recast to 4) in verse 3, and there is a subtly different descant for verse 4.

Which is to say, the sopranos (who may, at times, become accustomed simply to singing a familiar tune) faced some challenges.  In one of the verses last night, they dropped out, and did not manage to plug back in.

You kept from singing!, I observed.  However did you manage it?!
