The mass was commissioned by the Jesuit priest Father Ignaz Parhammer, who asked Mozart for music for the consecration of the new Orphanage Church – Waisenhauskirche [de] – on the Rennweg.[2] The commission gives the mass its nickname Waisenhausmesse (Orphanage Mass). Mozart also composed a trumpet concerto suitable for performance by a boy as well as an offertory, both thought to be lost.[2] Indeed, due to cataloging errors, this mass was also considered lost for many years.[3][4]
The first performance took place on 7 December 1768 at the church, in the presence of the court. The twelve-year-old Mozart conducted a choir of orphans in a performance that received "universal acclaim and admiration".[2] This mass is considered Mozart's most ambitious work to be performed up until that point in time,[5] and was his first and longest missa longa.[6]
