Remember that _singing is control of breath in exit_.
Exercise VI RAPID INSPIRATION WITH SLOW EXPIRATION Inhale through the nostrils quickly, deeply, and forcefully (one count); hold two counts; exhale through the nostrils evenly, steadily, and as slowly as possible while mentally counting one, two, three, four, etc.

With practice gradually increase the number of counts for the exhalation.
Exercise VII FARINELLI'S GREAT EXERCISE 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.
