Note 34 — Chapter XII
Reading edition
Browne and Behnke, in The Child's Voice, p. 75, state in reply to a questionnaire sent out to a large number of choir trainers, singers, et cetera, that seventy-nine persons out of one hundred fifty-two stated positively that singing through the period of puberty "causes certain injury, deterioration, or ruin to the after voice." In the same book are found also (pp. 85 to 90) a series of extremely interesting comments on the choirmaster's temptation to use a voice after it begins to change.
