When the lower note can be taken with the same resonance as the upper, the scale-passage from lower note upward may be attempted, always singing piano.
Exercise 10.
Right up the scale
Get into head-register sooner than is necessary; for instance, in the following take top C in head and bring down, as described in Ex. 9.
Exercise 11.
"Attack" first two notes, and after holding the upper octave a few seconds, glide to lower octave, striking note very softly, bringing upper register down. The soft ending is the test in this exercise. This exercise also prevents "scooping" in the first place, and teaches the use of high register on low notes.
Exercise 12.
Start in head-voice, sing very softly. In so doing, the voice will unconsciously get into the medium register, which is what is required.
Wrong head-tone production is combined with a loss of all facial expression, a fixed chin, and a stony eye.
