Piano Sonata No. 13 (Mozart)

from Wikipedia, the free encyclopedia
Wolfgang Amadeus Mozart (posthumous portrait by Barbara Krafft )

The piano sonata in B flat major, KV 333 (315c) , by Wolfgang Amadeus Mozart was composed in Linz at the end of 1783 .

It is now considered proven that this sonata with the piano sonata No. 6 KV 284 and violin sonata No. 32 KV 454 was published by Christoph Torricella on April 21, 1784 in Vienna . However, Mozart did not use the paper that he generally used in Vienna. The musicologist Alan Tyson therefore suggests that the piece was written in 1783, when Mozart made a long stop in Linz on the way from Salzburg to Vienna. From his point of view, this fits together with Mozart's Linz Symphony, which was composed at the same time , since both pieces have similar stylistic criteria.

The average duration of the sonata is around 23 minutes.

sentences

1st movement: Allegro

The first movement of this consistently lyrical and cantilever sonata has an upbeat: the main theme consists of a four-measure antecedent and a six-measure subsequent movement. The topic is repeated immediately, with the subsequent clause being changed in such a way that it merges with the transition and thus shortens the modulation. This is followed by the side theme, which is eight bars, is repeated immediately and begins in bar 23. This is followed by a final group consisting of scales with a clear fifth case sequence in bars 143–146 and the motifs are changed via G minor and D major . After 30 bars the recapitulation arrives completely in the tonic .

2nd movement: Andante cantabile

The second movement shows certain features of a sonata main movement : In the first eight bars the first theme appears, immediately in the same bar the second theme appears in the dominant . This is followed by a final group with transition to exposure or implementation . In the middle section, the motifs are changed in F minor . This is followed by the A 'part (the so-called recapitulation). Parts B and A 'must be repeated with the voltaic strokes .

3rd movement: Allegretto grazioso

The third movement shows certain features of a sonata rondo and corresponds to the scheme A – B – A – C – A – D – E – A. The headline of the couplet begins with quarters, the trailer consists of eighths. This four-bar theme is repeated and is the first group of themes to be changed in the next bar. Mozart designed bars 171 to 198 in the form of a cadenza and again sets a fifth case sequence in bars 189–193.
