'''Symphony No. 80''' in D minor, Hoboken 1/80, is a symphony composed by Joseph Haydn in 1784 as part of a trio of symphonies that also included symphonies 79 and 81. It is one of the relatively few later symphonies by Haydn to be in the minor mode. Symphony 80 is highly structured with both outer movements in sonata form. There is a common (though not strict) modulation pattern seen in all four movements.
