Random Quote

“The following few hints on the selection of voices may be useful: (1) Reject all boys who speak roughly, or sing coarsely; (2) Choose bright, intelligent-looking boys, provided they have a good ear; they will much more readily respond to the choirmaster’s efforts than boys who possess a voice and nothing more; therefore, (3) Reject dull, sulky, or scatter-brained boys, since it is hard to say which of the three has the most demoralizing effect on his more willing companions.”

— Sir Richard Runciman Terry (1912)
