If it is a difficult piece, is it worth the rehearsal time necessary to perform it well? Conversely, if it is not particularly difficult, will it stand up during the many rehearsals before the concert? These questions are quite important in the selection process. A piece must not be too difficult but it also should not be too easy. An error in either direction brings about its own type of choral repercussions.
If either error is made, in which direction is the error most compatible? It is best if every decision were correct and each piece contained enough complexity to keep the singers interested through the final rehearsals, but not so complex that the ensemble cannot realistically expect to perform it with control and artistry. There are other instances, to be sure, when you wish to offer a musical opportunity to your choir for educational reasons and the performance becomes secondary. When possible, it may be wise to sing and study such a work, but not perform it. Every piece that goes into the folder does not have to be placed on the concert program.
