IX. Sing the vowel "Ah" as in _father_ in such a manner
that it is a combination of the dark tone and
the strident tone.
X. Do this in such a way that all of the breathy
disagreeable features of the dark tone disappear
but its foundation features remain to give it fullness
and roundness, while all of the disagreeable
features of the strident tone disappear although
its color-giving, light-giving, life-giving characteristics
are retained to give the combination-tone
richness and sweetness. A beautiful result
is inevitable, if the principle is properly understood.
I have tried this with many people who
have sung but little before in their lives and who
were not conscious of having interesting voices.
Without a long course of vocal lessons or anything
of the sort they have been able to produce
in a short time--a very few minutes--a tone
that would be admired by any critic.
