Exercise XII
FOR FACILITY AND QUICK VOWEL CHANGE
Be careful not to blur the vowel sounds; each must be distinct and pure, and the change from one to the next must be made with a minimum of effort and without disturbing the focus of the tone.
The divisions (a and b) of each of the above four variants may be regarded as distinct exercises or not. For further practice use as initial consonants any or all of the following: b, p, m, f, v, d, k, n, t, and l.
Exercise XIII
ASCENDING AND DESCENDING SCALE
As in the previous exercises practise quietly with unvarying focus and aim to finish the phrase with breath unexhausted. Pitch the exercise to suit the voice.
