The Divertimento in E-flat major, K. 563 is a string trio written by Wolfgang Amadeus Mozart in 1788, the year in which he completed his last three symphonies and his “Coronation” Piano Concerto. It is widely regarded as separate from his other divertimenti.
The work was completed in Vienna on September 27, 1788, and is dedicated to Michael Puchberg, a fellow Freemason, who lent money to Mozart.
The premiere was in Dresden on April 13, 1789 with Anton Teyber taking the violin part, Mozart playing viola and Antonín Kraft playing cello. At the time Mozart was conducting a tour of German cities, on his way to Berlin.
The work has six movements.
