The Piano Sonata No. 18 in E♭ major, Op. 31, No. 3, is a sonata for solo piano by Ludwig van Beethoven, the third and last of his Op. 31 piano sonatas. The work dates from 1802. A playful jocularity is maintained throughout the piece, earning it the occasional nickname of The Hunt, although like many of Beethoven's early works, the 'jocular' style can be heard as a facade, concealing profound ideas and depths of emotion.
