Missa longa in C major
The Missa longa in C major, K. 262/246a, is a mass composed by Wolfgang Amadeus Mozart in May 1776. It is scored for SATB soloists, SATB choir, violin I and II, 2 oboes, 2 horns, 2 clarini (high trumpets), 3 trombones colla parte, timpani and basso continuo.
The mass is classed as a missa longa due to its length. However, due to its lack of extended writing for the solo parts, it has also been categorised as a missa brevis. The occasion the mass was composed for remains debatable. It may have been composed at the Archbishop Colloredo's request for a special occasion at the Salzburg Cathedral, or at the directive of a different priest – Colloredo's preference for brief settings makes it unlikely that he would have approved of the missa longa. Alternatively, it may have been composed for performance at St Peter's Church.
