It was his last full-length attempt at the sonata genre, the other completed ones being the Piano Sonata No. 1 in F♯ minor (Op. 11) and the Piano Sonata No. 3 in F minor (Op. 14); he later wrote Three Piano Sonatas for the Young Op. 118. Because it was published before the F minor sonata, it was given an earlier sequence number (No. 2) but still kept its later opus number (Op. 22). This has caused confusion, and recordings of the G minor Sonata have sometimes been published as "Sonata No. 3". There was also an earlier sonata in F minor, which Schumann abandoned; this is sometimes referred to as "Sonata No. 4".
