Mens Actions to all the necessary and useful Affairs of the
World. When in very different Ways, but with equal Pleasure and
Application, they contribute to the Order and Service of the
whole. Mr. _Dryden_ has given an Hint, how we may form a
beautiful and pleasing Idea of this from the Powers of Musick,
that arise from the Variety and artful Composition of Sounds.

_From Harmony, from Heavenly Harmony,
This Universal Frame began.
From Harmony to Harmony,
Thro' all the Compass of the Notes it ran,
The Diapasm closing full in Man._

There seems to be a wonderful Likeness in the natural Make of
Mens Minds to the various Tones and Measures of Sounds; and in
their Inclinations and most pleasing Tastes to the several Styles
and Manners of Musick. Something there is in the Mind, of alike
Composition, that is easily touch'd by the kindred Harmony of
Musick,

_For Man may justly tuneful Strains admire,
His Soul is Musick, and his Breast a Lyre._

We have all the Materials of Musick in the Tones and Measure. For
the infinite Variety Composition admits of, can be nothing else,
but higher or lower Tones, stronger or softer Sounds, with a
slower or swifter Motion. The Artist, by an harmonious Mixture
of these, makes the Musick either strong and martial, brisk and
airy, grave and solemn, or soft and moving.
