Piano Concerto No. 27 (Mozart)

The manuscript is dated 5 January 1791. However, Alan Tyson's analysis of the paper on which Mozart composed the work indicated that Mozart used this paper between December 1788 and February 1789, which implies composition well before 1791. Simon Keefe has written that the composition of the work dates from 1788. By contrast, Wolfgang Rehm has stated that Mozart composed this concerto in late 1790 and early 1791. Cliff Eisen has discussed the controversy over the time of composition in his review of the published facsimile of the score. == Premiere ==

The concerto may have been first performed at a concert on 4 March 1791 in Jahn's Hall by Mozart and the clarinetist Joseph Beer. If so, this was Mozart's last appearance in a public concert, Yet another possibility has been put forth by the Mozart scholar Wolf-Dieter Seiffert: that the work was not necessarily written for any particular performance venue, but rather for publication. The purchasing audience would have consisted largely of amateurs, intending to perform the concerto at home with a small group of friends. In support of this are three factors: the piano part is not that hard to play, the orchestra is modest in size, and Mozart included cadenzas and lead-ins, items that he himself would have improvised when performing. These traits are shared by the only other Mozart piano concertos published during his lifetime, namely K. 413–415. == Music ==

The work is scored for flute, two oboes, two bassoons, two horns in B, solo piano and strings, which makes it thinner than Mozart's other late concertos, all of which except for No. 23 have trumpet and timpani. It has three movements: Although all three movements are in a major key, minor keys are suggested, as is evident from the second theme of the first movement (in the dominant minor), as well as the presence of a remote minor key in the early development of that movement and of the tonic minor in the middle of the Larghetto. The principal theme for the finale was also used in Mozart's song "Sehnsucht nach dem Frühling" (also called ), K. 596, which immediately follows this concerto in the Köchel catalogue. Mozart wrote down his cadenzas for the first and third movements. Simon Keefe has discussed the concerto in detail, with emphasis on the distinctive character and experiments in style of the concerto compared to Mozart's other concerti in this genre. == References ==
