March in D Major K. 335, Serenade in D Major K. 320 "Posthorn-Serenade" & Symphony in D Major K. 385 "Haffner-Sinfonie"

This compilation of orchestral works is by Wolfgang Amadeus Mozart and dates from around 1779–1782. The music is rooted in the Classical style, with clear textures, balanced forms, prominent wind and horn writing and energetic string passages, and it comes from a phase in Mozart's career when he wrote more frequently for public and ceremonial occasions.
