Michael Haydn's Symphony No. 15 in D major, Perger 41, Sherman 15, MH 150, is believed to have been written in Salzburg after 1771. This work was at one time attributed to Joseph Haydn, the first work in D major so attributed.
The placement of the Minuet second, before the slow movement, is unusual in Michael Haydn's symphonies, though there is one other specimen, the Symphony No. 16, which scholars are fairly certain is a close contemporary to this one. Three symphonies by brother Joseph Haydn also have this placement, 32, 37 and 44.
