The Piano Sonata No. 16 in C major, K. 545, by Wolfgang Amadeus Mozart was described by Mozart himself in his own thematic catalogue as “for beginners”, and it is sometimes known by the nickname Sonata facile or Sonata semplice.
Mozart added the work to his catalogue on June 26, 1788, the same date as his Symphony No. 39. The exact circumstances of the work’s composition are not known, however. Although the piece is well-known today, it was not published in Mozart’s lifetime and first appeared in print in 1805.
This piece has a constantly moving left hand motif and many, many accidentals. Written in the Key of G, in 3/4 time, and it is four pages in length.
