See also:CONCERTO (See also:Lat. concertus, from certare, to strive, also See also:con-fused with concentus)
, in See also:music, a See also:term which appears as See also:early as the beginning of the 17th See also:century, at first as a See also:title of no very definite meaning, but which early acquired a sense justified by its See also:etymology and became applied chiefly to.compositions in which unequal instrumental or vocal forces are brought into opposition
.
Although by See also:Bach's See also:time the See also:concerto as a polyphonic instrumental See also:form was thoroughly established, the term frequently appears in the autograph title-pages of his See also: The da See also:capo form, by which the aria had attained its full dimensions through the addition of a second See also:strain in See also:foreign keys followed by the original strain da capo, was absorbed by the polyphonic concerto on an enormous scale, both in first movements and finales (see Bach's Klavier concerto in E, Violin concerto in E, first movement), while for slow movements the ground See also:bass (see See also:VARIATIONS), diversified by changes of key (Klavier concerto in D See also:minor), the more melodic types of binary form, sometimes with the repeats ornamentally varied or inverted (Concerto for 3 klaviers in D minor, Concerto for klavier, See also:flute and violin in A minor), and in finales the See also:rondo form (Violin concerto in E See also:major, Klavier concerto in F minor) and the binary form (3rd Brandenburg concerto) may be found . When conceptions of musical form changed and the See also:modern See also:sonata style arose, the See also:peculiar conditions of the concerto gave rise to problems the difficulty of which only the highest classical intellects could appreciate or solve . The number and contrast of the themes necessary to work out a first movement of a sonata are far too See also:great to be contained within the single musical See also:sentence of Bach's and See also:Handel's ritornello, even when it is as See also:long as the See also:thirty bars of Bach's See also:Italian concerto (a work in which every essential of the polyphonic concerto is reproduced on the See also:harpsichord by means of the contrasts between its full See also:register on the See also:lower of its two keyboards and its solo stops on both) . Bach's sons had taken shrewd steps in forming the new style; and Mozart, as a boy, modelled himself closely on Johann See also:Christian Bach, and by the time he was twenty was able to write concerto ritornellos that gave the orchestra admirable opportunity for asserting its See also:character and resource in the statement in charmingly epigrammatic style of some five or six sharply contrasted themes, afterwards to be-worked out with additions by the solo with the orchestra's co-operation and intervention . As the scale of the See also:works increases the problem becomes very difficult, because the See also:alternation between solo and Bass See also:concertina, single See also:action See also:Double bass concertina, single action tutti easily produces a sectional type of structure incompatible with the high degree of organization required in first movements; yet frequent alternation is evidently necessary, as the orchestral solo is audible only above a very subdued orchestral accompaniment, and it would be highly inartistic to use the orchestra for no other purpose . Hence in the classical concerto the ritornello is never abandoned, in spite of the enormous dimensions to which the sonata style expanded it . And though from the time of Mendelssohn onwards most composers have seemed to regard it as a conventional impediment easily abandoned, it may be doubted whether any modern concerto, except the four magnificent examples of See also:Brahms, and Dr See also:Joachim's Hungarian concerto, possesses first movements in which the orchestra seems to enjoy breathing space . And certainly in the classical concerto the entry of the solo instrument, after the long opening tutti, is always dramatic in See also:direct proportion to its delay . The great danger in handling so long an orchestral prelude is that the work may for some minutes be indistinguishable from a See also:symphony and thus the entry of the solo may be unexpected without being inevitable . This is especially the See also:case if the composer has treated his opening tutti like the exposition of a sonata movement, and made a deliberate transition from his first group of themes to a second group in a complementary key, even if the transition is only temporary, as in See also:Beethoven's C minor concerto . Mozart keeps his whole tutti in the tonic, relieved only by his mastery of sudden subsidiary modulation; and so perfect is his marshalling of his resources that in his hands a tutti a See also:hundred bars long passes by with the effect of a splendid See also:pageant, of which the meaning is evidently about to be revealed by the solo . After the C minor concerto, Beethoven grasped the true function of the opening tutti and enlarged it to his new purposes . With an interesting experiment of Mozart's before him, he, in his G major concerto, Op . 53, allowed the solo player to See also:state the opening theme, making the orchestra enter pianissimo in a foreign key, a wonderful incident which has led to the absurd statement that he "abolished the opening tutti," and that Mendelssohn in so doing has " followed his example." In this concerto he also gave considerable variety of key to the opening tutti by the use of an important theme which executes a considerable See also:series of modulations, an entirely different thing from a deliberate modulation from material in one key to material in another . His fifth and last See also:pianoforte concerto, in E See also:flat, commonly called the " See also:Emperor," begins with a rhapsodical introduction of extreme brilliance for the solo player, followed by a tutti of unusual length which is confined to the tonic major and minor with a strictness explained by the gorgeous modulations with which the solo subsequently treats the second subject . In this concerto Beethoven also dispenses with the only really conventional feature of the form, namely, the cadenza, a See also:custom elaborated from the operatic aria, in which the singer was allowed to extemporize a flourish on a pause near the end . A similar pause was made in the final ritornello of a concerto, and the soloist was supposed to extemporize what should be See also:equivalent to a symphonic See also:coda, with results which could not but be deplorable unless the player (or cadenza writer) were either the composer himself, or capable of entering into his intentions, like Joachim, who has written the finest extant cadenza of classical violin concertos . Brahms's first concerto in D minor, Op . 15, was the result of an immense amount of work, and, though on a mass of material originally intended for a symphony, was nevertheless so perfectly assimilated into the true concerto form that in his next See also:essay, the violin concerto, Op . 77, he had no more to learn, and was See also:free to make true innovations . He succeeds in presenting the contrasts even of remote keys so immediately that they are service-able in the opening tutti and give the form a wider range in definitely functional key than any other instrumental music . Thus in the opening tutti of the D minor concerto the second eubject is announced in B flat minor . In the B flat pianoforte concerto, Op . 83, it appears in D minor, and in the double concerto, Op . 102, for violin and See also:violoncello in A minor it appears in F major . In none of these cases is it in the key in which the solo develops it, and it is reached with a directness sharply contrasted with the symphonic deliberation with which it is approached in the solo . In the violin concerto, Op . 77, Brahms develops a counterplot in the opposition between solo and orchestra, inasmuch as after the solo has worked out its second subject the orchestra bursts in, not with the opening ritornello, but with its own version of the material with which the solo originally entered . In other words we have now not only the development by the solo of material stated by the orchestra but also a See also:counter-development by the orchestra of material stated by the solo . This concerto is, on the other See also:hand, remark-able as being the last in which a See also:blank space is See also:left for a cadenza, Brahms having in his friend Joachim a kindred spirit worthy of such See also:trust . In the pianoforte concerto in B flat, and in the double concerto,' Op . 102, the idea of an See also:introductory statement in which the solo takes part before the opening tutti is carried out on a large scale, and in the double concerto both first and second subjects are thus suggested . It is unnecessary to speak of the other movements of concerto form, as the sectional structure that so easily results from the opposition between solo and orchestra is not of great disadvantage to slow movements and finales, which accordingly do not show important See also:differences from the See also:ordinary types of symphonic and chamber music . The See also:scherzo, on the other hand, is normally of too small a range of contrast for successful See also:adaptation to concerto form, and the solitary great example of its use is the second movement of Brahms's B flat pianoforte concerto, Nothing is more easy to handle with inartistic or pseudo-classic effectiveness than the opposition between a brilliant solo player and an orchestra; and, as the inevitable tendency of even the most See also:artistic concerto has been to exhaust the resources of the solo instrument in the increased difficulty of making a proper contrast between solo and orchestra, so the technical difficulty of concertos has steadily increased until even in classical times it was so great that the orthodox definition of a concerto is that it is " an instrumental See also:composition designed to show the skill of an executant, and one which is almost invariably accompanied by orchestra." This idea is in flat violation of the whole See also:history and See also:aesthetics of the form, which can never be understood by means of a study of averages . In See also:art the See also:average is always false, and the individual organization of the greatest classical works is the only sound basis for generalizations, historic or aesthetic . (D . F . |
