This waste comes from exhaling more breath (more motive power) than the tone requires, and _breath that does not become tone is wasted_.

This fault is largely induced by lack of proper resonance adjustment.
The singer should always feel able to sing another note or to speak another word.

To sing or speak thirty or forty counts with one breath is useful practice but poor performance.

Occasionally, long runs in singing may compel an exception.

Half-empty lungs lower the pitch of the tone, lessen the resonance, and weaken the voice, rendering the last note of the song and the last word of the sentence inaudible.
