This article is a list of the musical compositions of Michael Haydn sorted by genre, and then chronologically when year of composition is indicated, otherwise alphabetically. The numbering in parentheses starting with the capital letter P refers to Perger catalogue. The MH numbers refer to the Sherman & Thomas catalog of 1993. Instrumental music Symphonies All of Michael Haydn's symphonies have at least 2 oboes, 2 bassoons, 2 horns and strings (first and second violins, violas and basses, but no cellos). Some symphonies add more instruments, such as trumpets and timpani in some of the C major symphonies. They are usually either in three or four movements. Continuo is explicitly called for only in the earlier works, and the modern editions usually follow the old practice of putting the bassoons, basses and the left hand of the continuo on a single staff below the violas' staff. Many of Michael Haydn's symphonies were at first attributed to Joseph Haydn. Only one of them was first attributed to Wolfgang Amadeus Mozart. Symphony No. 1 in C major, MH 23, Perger 35 (1758?)
