"For imparting flexibility to the voice, nothing can exceed the
Arpeggio, but like all vocal exercises, it must be produced with
precision of tone, singing each interval clearly, with careful
intonation, always striving for beauty of tone.
"There are various forms of arpeggios to be used. The second form is
carried a third above the octave; the third form a fifth above. This
makes an exercise which employs every tone in the scale save one, and
gives practice in rapid breathing. Remember, that the note before,
taking breath is slightly shortened, in order to give time for taking
breath, without disturbing the rhythm.
