Concerto in C major, Op. 56 "Triple Concerto"

Ludwig van Beethoven's Concerto for Violin, Cello, and Piano in C major, Op. 56, more commonly known as the Triple Concerto, was composed in 1803 and later published in 1804 by Breitkopf & Härtel. The choice of the three solo instruments effectively makes this a concerto for piano trio, and it is the only concerto Beethoven ever completed for more than one solo instrument. A typical performance takes approximately thirty-seven minutes.
