List of compositions by Ludwig van Beethoven

Beethoven composed works in all the main genres of classical music, including symphonies, concertos, string quartets, piano sonatas and opera.

Beethoven straddled both the Classical and Romantic periods, working in genres associated with Wolfgang Amadeus Mozart and his teacher Joseph Haydn, such as the piano concerto, string quartet and symphony, while on the other hand providing the groundwork for other Romantic composers, such as Hector Berlioz and Franz Liszt, with programmatic works such as his Pastoral Symphony and Piano Sonata "Les Adieux".

Although his output greatly diminished in his later years, this period saw the composition of masterpieces such as the late string quartets, the final five piano sonatas, the Diabelli Variations, the Missa Solemnis and the Ninth Symphony.

Some works are also commonly referred to by their nicknames, such as the Kreutzer Violin Sonata, or the Archduke Piano Trio.

Legend for publications – p: parts s: full score vs: vocal score Beethoven wrote nine symphonies, nine concertos, and a variety of other orchestral music, ranging from overtures and incidental music for theatrical productions to other miscellaneous "occasional" works, written for a particular occasion.

Beethoven is believed to have intended to write a Tenth Symphony in the last year of his life; a performing version of possible sketches was assembled by Barry Cooper.

(Hess 33) In addition to the 32 celebrated sonatas, Beethoven's work for solo piano includes many one-movement pieces, more than twenty sets of variations, most unpublished in his lifetime or published without opus number, and over thirty bagatelles, including the well-known "Für Elise".

While he completed only one opera, Beethoven wrote vocal music throughout his life, including two Mass settings, other works for chorus and orchestra (in addition to the Ninth Symphony), arias, duets, art songs (lieder), and true song cycles.

The opus numbers do not include all works that were published in Beethoven's lifetime nor are they in chronological order.

WoO is an abbreviation of "Werke ohne Opuszahl", German for "Works without Opus number".
