Beethoven's Piano Sonata No.8 in C minor is generally called the "Sonata Pathétique". It was so named by the composer's publisher due to the tragic nature of the music. It is in the key of C minor which had that important significance for both Mozart and Beethoven. However it is the slow movement of Beethoven's Sonata which is best known, and it is in the related key of A-flat major. The main theme is a slow, graceful and far from tragic melody accompanied by a relaxed figure in quavers (16th notes). After developing over intervening episodes the main theme returns but the accompaniment is now in the form of triplets making it a little more intense.

Because of the lyrical (song-like) nature of its theme, this movement can be arranged for other combinations of instruments, and you may wish to check out our arrangements for Viola and Piano and for Clarinet and Piano.
There is a huge variety in Beethoven's 32 Piano Sonatas, and we recommend that serious piano students obtain the complete set, which comes in either 2 or 3 volumes depending on the edition. The cheapest is the Schirmer edition because it is in only 2 volumes as follows - at "musicroom.com": Volume I and Volume II; at "sheetmusicplus.com": Volume I and Volume II.
