Symphony No. 37 (Mozart)
Michael Haydn symphony misattributed to Mozart / From Wikipedia, the free encyclopedia
This work is not by Mozart but was once attributed to him and given a place in the Köchel catalogue (K 444/425a + Anh A 53) as well as the above number. It is in fact Symphony No. 25 in G major by Michael Haydn, bearing the catalogue numbers P 16 and MH 334. The mistake, long ago corrected, resulted from a brief musical introduction (an adagio maestoso) added by Mozart to Haydn's symphony.
