Wolfgang Amadeus Mozart's Piano Sonata No. 1 in C major, K. 279 / 189d (1774), is a piano sonata in three movements. It was composed when Mozart was only 18 years old and is the first of a set of his 18 piano sonata. All but 2 of the sonatas, No. 8 in A minor and No. 14 in C minor are in a major key. Also, the first several sonatas seem to follow the cycle of fifths, to the flat side first (No. 1 in C major, No. 2 in F major, No. 3 in B-flat major, No. 4 in E-flat major) and then to the sharp side (No. 5 in G major, No. 6 in D major).
