The young Beethoven composed his Trio Op. 11 for piano, cello and clarinet, this relatively new woodwind instrument becoming rapidly popular in his time. The nickname “Gassenhauer” trio is due to the widely popular tune used in the 3rd movement, used in an opera by Joseph Weigl.

The Clarinet Trio Op. 38 is an arrangement by the composer of his own Septet Op. 20, one of his most popular works during his lifetime, and Beethoven milked out its popularity by making several arrangements of it.

Trio Origo (Asko Heiskanen, clarinet, Jussi Seppänen, cello, Jerry Jantunen, fortepiano) is a Finnish trio performing Classical and early Romantic music on period instruments.
