Missa tempore Quadragesimae (Michael Haydn)

[5] In the following table of the movements, the markings, keys and time signatures are taken from the choral score of the Carus edition, using the symbol for alla breve (2/2).

[1] The mass was first published around 1820, possibly 1827, in Augsburg by Anton Böhme, titled Missa in tempore Adventus et Quadragesimae and supplemented by J. Eybler, who added a Gloria and a second Et incarnatus.

It appeared in Vienna in 1915, edited by Anton Maria Klafsky, in Denkmäler der Tonkunst in Österreich, volume 45, by the Österreichischer Bundesverlag.

A review notes its "beautiful, concise soberness unlike anything in the Mozart oeuvre or that of anyone else",[6] pointing at the section "Et incarnatus est" which is free in tempo, similar to harmonized chant.

[7] A reviewer notes the homophonic setting and simple rhythm, resulting in a floating meditative sound.
