Piano Sonata No. 3 (Beethoven)
Ludwig van Beethoven's Piano Sonata No. 3 in C major, Op. 2, No. 3, is a sonata written for solo piano, composed in 1795. It is dedicated to Joseph Haydn and is often referred to as Beethoven's first virtuosic piano sonata. The three Op. 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 Op. 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 Major, Op. 7, published a year later.
Viola Sonata (Mendelssohn)
Felix Mendelssohn composed his Viola Sonata in C minor, MWV Q 14, when he was only 15 years old. The autograph score is dated 14 February 1824. The work was not published in Mendelssohn's lifetime - in fact not until 1966 - and it was not assigned an opus number. Although he did reuse one of the themes from the minuet movement in the equivalent movement of his First Symphony.
