The three early Masses ("Windhaager Messe", "Kronstorfer Messe" and "Messe für den Gründonnerstag"), composed between 1842 and 1844, were short Austrian "Landmessen" for use in local churches and did not always set all the numbers of the ordinary. His Requiem in D minor of 1849 is the earliest work Bruckner himself considered worthy of preservation. It shows the clear influence of Mozart's Requiem (also in D minor) and similar works of Michael Haydn. The seldom performed "Missa solemnis", composed in 1854 for Friedrich Mayer's installation, was the last major work Bruckner composed before he started to study with Simon Sechter, with the possible exception of Psalm 146, a large work, for SATB soloists, double choir and orchestra.
