These two Aequali for three trombones are really works of Bruckner's youth, for he was only 22 years old when he composed them for the funeral of his great-aunt in January 1847. He was at that time a school assistant at the St Florian Monastery near Linz. in spite of the pieces' early date, the romantic, expressive harmonies of the two brief Aequale already reveal the "true" Bruckner, and look forwards to the chorale-like trombone passages in his later symphonies. Together with Beethoven's Three Equali for four trombones WoO 30 (HN 1151) they are among the classics of the trombone repertoire. This Henle Urtext edition is based on the autograph sources in the monastery libraries of St Florian and Seitenstetten. The bass trombone part for the second Aequale is no longer extant, so Henle offers a suggested reconstruction to enable the work to be performed.
