The Mass No. 3 in F minor WAB 28 by Anton Bruckner is a setting of the mass ordinary for vocal soloists, chorus, orchestra and organ. After the 1867 success of Bruckner's Mass No. 1 in D minor, he was commissioned "to write a new Mass for the Burgkapelle." Bruckner wrote the first version between Septembers 1867 - 1868, in Linz (just before his move to Vienna) made slight revisions in 1877 and 1881, in preparation for performances at the Hofkapelle, mainly to address "difficulties of execution" but also to take into account what he had learned from studying Mozart's Requiem, correcting some instances of parallel octaves if not justified by Mozart's example, In the 1890s Bruckner was still revising the work, but there were very little changes made to the vocal parts after 1868.
