Harold Newton Clare, The Choirmaster's Manual (1908)
“ The first essential of a good choirmaster is discipline; no amount of learning can compensate for the lack of it. A certain amount of self-confidence is necessary to impress those being taught that the choirmaster knows what he wants and is going to get it; at the same time, all appearance of conceit should be suppressed, and corrections should be made without any "showing off" at the expense of a chorister, avoiding all remarks likely to hurt feelings. "Suggestions" from adult members of a choir should be ignored, if offered in public ”
