§ 19. The little Experience of some that teach to Sol-fa, obliges the Scholar to hold out the Semibreves with Force on the highest Notes; the Consequence of which is, that the Glands of the Throat become daily more and more inflamed, and if the Scholar loses not his Health, he loses the treble Voice.

§ 20. Many Masters put their Scholars to sing the Contr'Alto, not knowing how to help them to the Falsetto, or to avoid the Trouble of finding it.

§ 21. A diligent Master, knowing that a Soprano, without the Falsetto, is constrained to sing within the narrow Compass of a few Notes, ought not only to endeavour to help him to it, but also to leave no Means untried, so to unite the feigned and the natural Voice, that they may not be distinguished; for if they do not perfectly unite, the Voice will be of divers[12] Registers, and must consequently lose its Beauty. The Extent of the full natural Voice terminates generally upon the fourth Space, which is C; or on the fifth Line, which is D; and there the feigned Voice becomes of Use, as well in going up to the high Notes, as returning to the natural Voice; the Difficulty consists in uniting them. Let the Master therefore consider of what Moment the Correction of this Defect is, which ruins the Scholar if he overlooks it. Among the Women, one hears sometimes a Soprano entirely di Petto, but among the Male Sex it would be a great Rarity, should they preserve it after having past the age of Puberty. Whoever would be curious to discover the feigned Voice of one who has the Art to disguise it, let him take Notice, that the Artist sounds the Vowel i, or e, with more Strength and less Fatigue than the Vowel a, on the high Notes.

§ 22. The Voce di Testa has a great Volubility, more of the high than the lower Notes, and has a quick Shake, but subject to be lost for want of Strength.

§ 23. Let the Scholar be obliged to pronounce the Vowels distinctly, that they may be heard for such as they are. Some Singers think to pronounce the first, and you hear the second; if the Fault is not the Master's, it is of those Singers, who are scarce got out of their first Lessons; they study to sing with Affectation, as if ashamed to open their Mouths; others, on the contrary, stretching theirs too much, confound these two Vowels with the fourth, making it impossible to comprehend whether they have said Balla or Bella, Sesso or Sasso, Mare or More.

§ 24. He should always make the Scholar sing standing, that the Voice may have all its Organization free.

§ 25. Let him take care, whilst he sings, that he get a graceful Posture, and make an agreeable Appearance.

§ 26. Let him rigorously correct all Grimaces and Tricks of the Head, of the Body, and particularly of the Mouth; which ought to be composed in a Manner (if the Sense of the Words permit it) rather inclined to a Smile, than too much Gravity.

§ 27. Let him always use the Scholar to the Pitch of Lombardy, and not that of Rome;[13] not only to make him acquire and preserve the high Notes, but also that he may not find it troublesome when he meets with Instruments that are tun'd high; the Pain of reaching them not only affecting the Hearer, but the Singer. Let the Master be mindful of this; for as Age advances, so the Voice declines; and, in Progress of Time, he will either sing a Contr'Alto, or pretending still, out of a foolish Vanity, to the Name of a Soprano, he will be obliged to make Application to every Composer, that the Notes may not exceed the fourth Space (viz., C) nor the Voice hold out on them. If all those, who teach the first Rudiments, knew how to make use of this Rule, and to unite the feigned to the natural Voice, there would not be now so great a scarcity of Soprano's.

§ 28. Let him learn to hold out the Notes without a Shrillness like a Trumpet, or trembling; and if at the Beginning he made him hold out every Note the length of two Bars, the Improvement would be the greater; otherwise from the natural Inclination that the Beginners have to keep the Voice in Motion, and the Trouble in holding it out, he will get a habit, and not be able to fix it, and will become subject to a Flutt'ring in the Manner of all those that sing in a very bad Taste.
