It was an interesting challenge to arrange "Overture to the Marriage of Figaro" for eight voices. The Swingle Singers group has often used it to open a concert. Of course it is very difficult but quite a few choirs have managed to master it. I think it works equally well on or off mikes, as long as a proper balance is maintained among the voices. This is the first of the four movements of Mozart's "Eine Kleine Nacthmusik," all four of which Ward Swingle has arranged for voices with the hopes that groups will perform "Eine Kleine Nachtmusik" in its entirety. For the Swingle Singers this offered a change from the succession of 2- or 3-minutes pieces typical of many of our programs.
