_Airs_ accompanied only a Bass, the Application of him who
studies Graces is only subject to Time, and to the Bass; but in those,
that are accompanied with more Instruments, the Singer must be also
attentive to their Movement, in order to avoid the Errors committed by
those who are ignorant of the Contrivance of such Accompaniments.

Sec. 12. To prevent several false Steps in singing the _Airs_, I would
strongly inculcate to a Student, first, never to give over practising in
private, till he is secure of committing no Error in Publick; and next,
that at the first Rehearsal the _Airs_ be sung without any other
Ornaments than those which are very natural; but with a strict
Attention, to examine at the same time in his Mind, where the artificial
ones may be brought in with Propriety in the second; and so from one
Rehearsal to another, always varying for the better, he will by Degrees
become a great Singer.

Sec. 13. The most necessary Study for singing _Airs_ in Perfection, and
what is more difficult than any other, is to seek for what is easy and
natural, as well as of beautiful Inventions. One who has the good
Fortune to unite such two rare Talents, with an agreeable _putting
forth_ of the Voice, is a very happy Singer.

Sec. 14. Let him, who studies under the Disadvantage of an ungrateful
Genius, remember for his Comfort, that singing in Tune, Expression,
_Messa di Voce_, the _Appoggiatura's_, _Shakes_, _Divisions_, and
accompanying himself, are the principal Qualifications; and no such
insuperable Difficulties, but what may be overcome. I know, they are not
sufficient to enable one to sing in Perfection; and that it would be
Weakness to content one's self with only singing tolerably well; but
Embellishments must be called in to their aid, which seldom refuse the
Call, and sometimes come unsought. Study will do the business.

Sec. 15. Let him avoid all those Abuses which have overspread and
established themselves in the _Airs_, if he will preserve Musick in its
Chastity.

Sec. 16. Not only a Scholar, but every Singer ought to forbear
_Caricatura's_, or mimicking others, from the very bad Consequences that
attend them. To make others laugh, hardly gains any one Esteem, but
certainly gives Offence; for no-body likes to appear ridiculous or
ignorant. This Mimicking arises for the most part from a concealed
Ambition to shew their own Merit, at another's Expence; not without a
Mixture of Envy and Spight. Examples shew
