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.
Piano Sextet (Mendelssohn)
Felix Mendelssohn's Sextet in D major, Op. 110, MWV Q 16, for piano, violin, two violas, cello, and double bass was composed in April-May 1824, when Mendelssohn was only 15, the same time he was working on a comic opera "Die Hochzeit des Camacho". Its composition took place between the Viola Sonata and the Piano Quartet No. 3. It also preceded the famous Octet, Op. 20 by about a year. 1824 is also the probable year of the composition of the Clarinet Sonata. Like the latter, the Sextet was not published during the composer's lifetime. Its first edition was issued in 1868 as a part of a complete collection of Mendelssohn's works. Hence the misleading high opus number.
