Anton Bruckner composed about 40 motets during his life, the earliest, a setting of Pange lingua, in c. 1835, the last, Vexilla regis in 1892.
Before 1841 only a single work, a motet, has indubitably been composed by Bruckner.
The few other works of this period in Grasberger's catalogue are either obviously not by Bruckner or of doubtful authenticity. Domine, ad adjuvandum me festina ("O Lord, make haste to help me"; WAB 136) is a composition of Johann Baptist Weiß. The five preludes in E-flat major for organ (WAB 127 and 128) and a few other organ works found in Bruckner's Orgelbuch are presumably transcriptions of works of Johann Baptist Weiß or other composers.
Between 3 October 1841 and 23 September 1845, during his stay as schoolteacher's assistant in Windhaag and Kronstorf, successively, Bruckner composed the three early masses Windhaager Messe, Kronstorfer Messe, and Messe für den Gründonnerstag. During his stay in Kronstorf he composed also his first name-day cantata Vergißmeinnicht and a few motets:
Between 23 September 1845 and 24 December 1855, during his stay as organist in Sankt Florian monastery, Bruckner composed the Magnificat, the Requiem, the Missa solemnis, Psalms 22 and 114, and four name-day cantatas Entsagen, the Arneth Cantata, the Mayer Cantata, and the Festgesang, as well as the following motets:
