K. 457 The Piano Sonata No. 14 in C minor,

Mozart composed and completed his 14th piano sonata, in c minor (K 457),  in 1784, with the official date of completion recorded as October 14, 1784 in Mozart’s private catalogue of works. It was published in December of 1785 together with the Fantasy in C minor, by the publishing firm Artaria, Mozart’s main Viennese publisher. The title page bore a dedication to Thérèse von Trattner, who was one of Mozart’s pupils in Vienna. Her husband was an important publisher as well as Mozart’s former landlord. Eventually, the Trattners would become godparents to four of Mozart’s children. The sonata was composed during the approximately 10-year period of Mozart’s life as a freelance artist in Vienna after he removed himself from the patronage of the Archbishop of Salzburg in 1781. It is one of the earliest of only six sonatas composed during the Vienna years.
