Ludwig van Beethoven's Piano Sonata No. 3 in C major, Op. 2, No. 3, is a sonata written for solo piano, composed in 1796. It is dedicated to Joseph Haydn and is often referred to as Beethoven's first virtuosic piano sonata. The three Opus 2 sonatas all contain four movements each, an unusual length which seems to show that Beethoven was aspiring towards composing a symphony. It is both the weightiest and longest of the three Opus 2 sonatas, lasting over 25 minutes, presenting many difficulties, including difficult trills, awkward hand movements, and forearm rotation. It is Beethoven's second longest piano sonata in his early period, only to Beethoven's Grand Sonata in E-flat Major, Op. 7, published a year later.
