The Cavalier, Don Carlo Broschi, better known as Farinelli (1705-1782), the world's greatest singer in bravura and coloratura, was a pupil of Porpora and Bernacchi. There was no branch of the art which he did not carry to the highest perfection, and the successes of his youth did not prevent him from continuing his study, or, when his name was famous, from acquiring by much perseverance another style and a superior method. His breath control was considered so marvelous in that day of great singers, it is said, that the art of taking and keeping the breath so softly and easily that no one could perceive it began and died with him. He is said to have spent several hours daily in practising the following exercise:
As in [Exercise III], sip the breath slowly and steadily through the smallest possible opening of the lips; hold it a few counts, then exhale very slowly and steadily through the smallest possible opening of the lips.
Farinelli's exercise is not for beginners.
Exercise VIII
THE CLEANSING BREATH
For ventilating and sweeping the lungs, for quick refreshment after fatigue, and for use always at the close of your exercises, inhale through the nostrils slowly a complete breath; hold two to four counts, purse the lips tightly and expel through them a small puff of air, hold two counts, puff one, hold two counts, puff one, and so on until the exhalation is complete. A few trials should convince you that this simple exercise is of great value.
HALF-BREATH
In both singing and speaking, the sustained delivery of long phrases or sentences sometimes makes unusual demands on the breath supply. It is a law of good singing that every phrase should end with the breath unexhausted. When the flow of text and music forbid the taking of a full breath, half-breaths must be quietly taken at convenient points. Instead of letting the whole reservoir of motive power exhaust itself and then completely refill it, we should, by taking these half-breaths, maintain a reserve. A notable advocate of the use of the half-breath in singing is that past mistress of sustained and smooth delivery, Marcella Sembrich.
