Nonmusical considerations
While the general considerations are important musical bases for the choice of music, it is also true that factors other than musical ones often enter into the selection of music. These may include music for specific occasions, rehearsal time, lack of instruments, lack of reading skills by the choir, a mediocre or poor accompanist, lack of funds to purchase desired music, and still others that are peculiar to any given situation.
Another most important factor to consider, in addition to the amount of time that has to be spent searching for repertoire (which is considerable), is the type of time that must be used in this search. This refers to the fact that not only is this task extremely time-consuming, but that most of it must be done on the choral director's own time, outside the normal teaching day. Most schools allow a small portion of each day for planning but, in reality, most of this time is spent either complying with the latest paperwork request from the principal's office or spending some deserved moments relaxing in the teacher's lounge.
