"I give many vocalizes and exercises, which I invent to fit the needs of
each pupil. I do not require them to be written down, simply remembered.
At the next lesson quite a different set of exercises may be
recommended. I also make exercises out of familiar tunes or themes from
operatic airs. It will be found that technical material in the various
manuals is often chosen from such sources, so why not use them in their
original form. Thus while the student is studying technic he is also
acquiring much beautiful material, which will be of great value to him
later on.
