Beethoven Allegretto for Piano Trio, WoO 39

Ludwig van Beethoven composed the Allegreto for Piano Trio in 1812. It was first published in 1830, though at the time it probably wasn't considered a major work, as it doesn't have it's own Opus number. It is is written in the key of B-flat major and dedicated to Beethoven's friend Maximiliane Brentano (1802-1861).
