Piano Concerto No. 24 (Mozart)

Mozart composed the concerto in the winter of 1785–86, during his fourth season in Vienna. It was the third in a set of three concertos composed in quick succession, the others being No. 22 in E major and No. 23 in A major. Mozart finished composing the No. 24 shortly before the premiere of his comic opera The Marriage of Figaro; the two works are assigned adjacent numbers of 491 and 492 in the Köchel catalogue. Although composed at the same time, the two works contrast greatly: the opera is almost entirely in major keys while the concerto is one of Mozart's few minor-key works. The premiere of the concerto was on either 3 or 7 April 1786 at the Burgtheater in Vienna; Mozart featured as the soloist and conducted the orchestra from the keyboard. In 1800, Mozart's widow, Constanze, sold the original score of the work to the publisher Johann Anton André of Offenbach am Main. It passed through several private hands during the nineteenth century before Sir George Donaldson, a Scottish philanthropist, donated it to the Royal College of Music in 1894. The College still houses the manuscript today. The original score contains no tempo markings; the tempo for each movement is known only from the entries Mozart made into his catalogue. The orchestral parts in the original score are written in a clear manner. The solo part, on the other hand, is often incomplete: on many occasions in the score Mozart notated only the outer parts of passages of scales or broken chords. This suggests that Mozart improvised much of the solo part when performing the work. The score also contains late additions, including that of the second subject of the first movement's orchestral exposition. There is the occasional notation error in the score, which musicologist Friedrich Blume attributed to Mozart having "obviously written in great haste and under internal strain". ==Music==

Overview The concerto is divided into the following three movements: This is the largest array of instruments for which Mozart composed any of his concertos. It is one of only two of Mozart's piano concertos that are scored for both oboes and clarinets (the other, his concerto for two pianos, has clarinets only in the revised version). The clarinet was not at the time a conventional orchestral instrument. Robert D. Levin writes: "The richness of wind sonority, due to the inclusion of oboes and clarinets, is the central timbral characteristic of [the concerto]: time and again in all three movements the winds push the strings completely to the side." Exposition The orchestral exposition, 99 measures long, presents two groups of thematic material, one primary and one secondary, both in the tonic of C minor. Another departure from convention is that the solo exposition does not re-state the secondary theme from the orchestral exposition. Instead, a succession of new secondary thematic material appears. Musicologist Donald Tovey considered this introduction of new material to be "utterly subversive of the doctrine that the function of the opening tutti [the orchestral exposition] was to predict what the solo had to say." and which Tovey describes as a passage of "fine, severe massiveness". Many later composers and performers, including Johannes Brahms, Ferruccio Busoni, Alfred Schnittke and Gabriel Fauré, have composed their own. Uniquely among Mozart's concertos, the score does not direct the soloist to end the cadenza with a cadential trill. The omission of the customary trill is likely to have been deliberate, with Mozart choosing to have the cadenza connect directly to the coda without one. The conventional Mozartian coda concludes with an orchestral tutti and no written-out part for the soloist. In this movement, Mozart breaks with convention: the soloist interrupts the tutti with a virtuosic passage of sixteenth notes and accompanies the orchestra through to the final pianissimo C-minor chords. II. Larghetto Alfred Einstein said of the concerto's second movement that it "moves in regions of the purest and most moving tranquility, and has a transcendent simplicity of expression". Marked Larghetto, the movement is in E major and cut common time. The trumpets and timpani play no part; they return for the third movement. The movement opens with the soloist playing the four-measure principal theme alone; it is then repeated by the orchestra. {{block indent| \relative c'' { \set Score.tempoHideNote = ##t \tempo 8 = 100 \key es \major \time 2/2 bes4^\markup { \column { \line { Principal theme } \line { \bold { Larghetto } } } } bes8. bes16 bes8( es) es4 g8( d es f) bes,2 g'4 g8. g16 bes8.( g16) es4 d,8 d d d es4 r4 } }} This theme is, in the words of Michael Steinberg, one of "extreme simplicity". Donald Tovey refers to the fourth bar, extremely bare and lacking any ornamentation, as "naive", but considers that Mozart intended for it to be so. After the orchestra repeats the principal theme, there is a very simple bridge or transitional passage that Girdlestone calls "but a sketch" to be ornamented by the soloist, arguing that "to play it as printed is to betray the memory of Mozart". Following the bridge passage, the soloist plays the initial four-measure theme for a second time, before the orchestra commences a new section of the movement, in C minor. A brief return of the principal theme, its rhythm altered, The form of the movement is nearly identical to that of the second movement of Mozart's Piano Sonata in B major, K. 570. III. Allegretto The third movement features a theme in C minor followed by eight variations upon it. Hutchings considered it "both Mozart's finest essay in variation form and also his best concerto finale." {{block indent| \relative c'' { \set Score.tempoHideNote = ##t \tempo 4 = 112 \key c \minor \time 2/2 \partial 4 g4\p(^\markup { \column { \line { Theme } \line { \bold { Allegretto } } } } es) es( d) d( c) r r g'( c) c( es fis,) g r r g( aes) aes-.( aes-. aes-.) \grace { aes32( bes32} c4) bes8 aes g4 g \break \grace { g32( a32} bes4) a!8 g g4( fis) \partial 2. g r r \bar ":..:" \partial 4 g( f) g( es) g( d) r r aes''~ aes( g fis f) es r r c( \break des) des-.( des-. des-.) \grace { des32( es32} f4) es8 des! c4 c \grace { c32( d!32} es4) d8 c c4( b) \partial 2. c r r \bar ":|." } }} The tempo marking for the movement is Allegretto. Rosen opines that this calls for a march-like speed and argues that the movement is "generally taken too fast under the delusion that a quick tempo will give it a power commensurate with that of the opening movement." Variations II to VI are what Girdlestone and Hutchings independently describe as "double" variations. Within each variation, each of the eight-measure phrases from the theme is further varied upon its repeat (AXAYBXBY). Between the two major-key variations, Variation V returns to C minor; Girdlestone describes this variation as "one of the most moving". Variation VII is half the length of the preceding variations, as it omits the repeat of each eight-measure phrase. ==Critical reception==

(pictured) in Vienna.Ludwig van Beethoven admired the concerto and it may have influenced his Piano Concerto No. 3, also in C minor. Among modern and twentieth-century scholars, Cuthbert Girdlestone states that the concerto "is in all respects one of [Mozart's] greatest; we would fain say: the greatest, were it not impossible to choose between four or five of them." Referring to the "dark, tragic and passionate" nature of the concerto, Alfred Einstein states that "it is hard to imagine the expression on the faces of the Viennese public" when Mozart premiered the work. The musicologist Simon P. Keefe, in an exegesis of all of Mozart's piano concertos, writes that the No. 24 is "a climactic and culminating work in Mozart's piano concerto oeuvre, firmly linked to its predecessors, yet decisively transcending them at the same time." The verdict of the Mozart scholar Alexander Hyatt King is that the concerto is "not only the most sublime of the whole series but also one of the greatest pianoforte concertos ever composed". Arthur Hutchings's view is that "whatever value we put upon any single movement from the Mozart concertos, we shall find no work greater as a concerto than this K. 491, for Mozart never wrote a work whose parts were so surely those of 'one stupendous whole'." ==Notes, references and sources==
