Piano Sonata No. 17 (Mozart)
# Piano Sonata No. 17 (Mozart)

Wolfgang Amadeus Mozart's Piano Sonata No. 17 in B♭ major, K. 570, dated February 1789, is a sonata in three movements:

* Allegro in $^3$ $_4$
* Adagio (E♭ major) in $^4$ $_4$
* Allegretto in $^2$ $_4$

A typical performance takes about 18 minutes.

There is an accompanying violin part of doubtful origin in many 1800 editions; the piano part is exactly the same as for piano solo. Neue Mozart-Ausgabe (NMA) describe it as an addition by either Johann Anton André or Johann Mederitsch [de].
