any one Term which is made Use of, in the Science of Music.
Above three Parts in four make Use of it, without having any Meaning of their own, only having heard some one else observe, that such or such a Person plays with great Expression, they take a Fancy to this new adopted Child, and become as fond of it, as if it was the legitimate Offspring of their own Brain. Some who are more considerate, think that the Meaning of it entirely consists in playing Staccato; and indeed these People come nearer the Mark than the others, but they have not picked up all the Meaning of the Word.
One who plays with Expression, is he who, in his Performance, gives the Air or Piece of Music (let it be what it will) such a Turn, as conveys that Passion into the Hearts of the Audience, which the Composer intended to excite by it. Dryden, in that masterly Poem, his Ode in Honour of St. Cecilia's Day, has given us a true
Idea of the Meaning of the Word; the Beauties of which Poem, though they are enough to hurry any Man away from his Subject, shall not be discussed at present, not being to the Point in Hand. We shall only make Use of an Instance or two out of it, to illustrate what has been said.
Handel was so sensible of it's being capable, by the Help of Musical Sounds, of raising those very Passions in the Hearts of the Audience, which Dryden fables Alexander to have felt by the masterly Hand of Timotheus, that, by setting it to Music, he has himself boldly stepped into the Place of Timotheus.
In this Performance called Alexander's Feast, it may easily be discerned, that Expression does not consist in the Staccato only, or in any one Power or Manner of playing. For Instance this Air,
Softly sweet in Lydian Measures, &c.
would be quite ruined by playing it Staccato; and again,
Revenge, Revenge, Timotheus cries, &c.
