Wolfgang Amadeus Mozart's Piano Sonata No. 10 in C Major, K 330 (300h) was composed in 1783, when Mozart was twenty-seven years old. It was published, with two other sonatas (K. 331 and 332), by Artaria in 1784. A typical performance of this sonata lasts around 20 minutes.
This is one of Mozart's most popular piano sonatas, and has been featured in classical music-related films, such as Sparky's Magic Piano. Mozart's autograph of the sonata is held in the Jagiellonian Library, Kraków.
