Anton Diabelli (1781 – 1858) was an Austrian music editor, publisher, pianist, guitarist, and composer. He learned music at a young age and began to compose for both piano and guitar while living in Salzburg. In 1803 he moved to Vienna where he learned the music publishing business and started a firm with partner Pietro Cappi in 1818.
Diabelli wrote many piano compositions and he is most well known for writing the waltz on which Ludwig van Beethoven wrote his Diabelli Variations (Op.120). However, the greatest number of his works were written for the guitar.
Among Diabelli’s substantial works for guitar are an Ouverture and a march on the death of Michael Haydn (one of Diabelli’s early teachers).
