Symphony no. 38 in D major, K.504, "Prague"

The Symphony No. 38 in D major, K. 504, was composed by Wolfgang Amadeus Mozart in late 1786. It premiered in Prague on 19 January 1787, during Mozart's first visit to the city. Because it was first performed in Prague, it is often called the Prague Symphony. Mozart's autograph thematic catalogue records 6 December 1786 as the date of completion. Other works written by Mozart roughly contemporary with this symphony include the Piano Trio in B♭, K. 502 (completed 18 November 1786), the Piano Concerto No. 25, K. 503 (completed 4 December 1786), and the scena and rondò concert aria Ch'io mi scordi di te?, K. 505, for soprano and orchestra (completed 26 December 1786).
