a place where the performer might indulge in a flourish of his own. There is a tradition that Mozart once remarked: "Wherever I smear that thing," indicating a hold, "you can do what you please;" the rule is, however, that the only privilege which the cadenza opens to the player is that of improvising on material drawn from the subjects already developed, and since, also as a rule, composers are generally more eloquent in the treatment of their own ideas than performers, it is seldom that a cadenza contributes to the enjoyment afforded by a work, except to the lovers of technique for technique's sake. I never knew an artist to make a more sensible remark than did M. Ysaye, when on the eve of a memorably beautiful performance of Beethoven's violin concerto, he said: "If I were permitted to consult my own wishes I would put my violin under my arm when I reach the fermate and say: 'Ladies and gentlemen, we have reached the cadenza. It is presumptuous in any musician to think that he can have anything to say after Beethoven has finished. With your permission we will consider my cadenza played.'" That Beethoven may himself have had a thought of the same nature is a fair inference from the circumstance that he refused to leave the cadenza in his E-flat pianoforte concerto to the mercy of the virtuosos but wrote it himself.
Concertos.
Chamber music.
Concertos for pianoforte or violin are usually written in three movements, of which the first and last follow the symphonic model in respect of elaboration and form, and the second is a brief movement in slow or moderate time, which has the character of an intermezzo. As to the nomenclature of chamber music, it is to be noted that unless connected with a qualifying word or phrase, "Quartet" means a string quartet. When a pianoforte is consorted with strings the work is spoken of as a Pianoforte Trio, Quartet, or Quintet, as the case may be.
The Overture.
Pot-pourris.
The form of the overture is that of the first movement of the sonata, or symphony, omitting the repetition of the first subdivision. Since the original purpose, which gave the overture its name (Ouverture = aperture, opening), was to introduce a drama, either spoken or lyrical, an oratorio, or other choral composition, it became customary for the composers to choose the subjects of the piece from the climacteric moments of the music used in the drama. When done without regard to the rules of construction (as is the case with practically all operetta overtures and Rossini's) the result is not an overture at all, but a pot-pourri, a hotch-potch of jingles. The present beautiful form, in which Beethoven and other composers have shown that it is possible to epitomize an entire drama, took the place of an arbitrary scheme which was wholly aimless, so far as the compositions to which they were attached were concerned.
