Symphonies nos. 31 "Paris" / 35 "Haffner" / 36 "Linz" is a collection of symphonies by Wolfgang Amadeus Mozart, composed in 1778, 1782 and 1783. They are Classical-era symphonies with lively wind parts and energetic string textures within clear sonata and symphonic forms, and they come from a period when Mozart expanded his orchestral forces and wrote for larger public performances.
