Mass in C major, K. 258 "Piccolomini"
The Missa brevis No. 7 in C major, K. 258, is a mass composed by Wolfgang Amadeus Mozart, probably in 1776. It is scored for SATB soloists, SATB choir, violin I and II, 2 oboes, 2 clarini (high trumpets), 3 trombones colla parte, timpani and basso continuo.
The mass is often referred to as the Spaur Mass, although this is misleading; Leopold Mozart wrote in 1788 of a mass the family nicknamed the Spaur, as Wolfgang had written it for the consecration of Count Ignaz Joseph von Spaur. However, this could refer to one of many masses, including K. 257, K. 262 and K. 275/272b. The original score of this mass was discovered in the archives of the Brixen Cathedral in 2007; this provides another link to the Spaur family, some of whom held power in the Bishopric of Brixen.
The mass is divided into six movements.
- "Kyrie" Allegro, 3/4
- "Gloria" Allegro, common time
- "Credo" Allegro, 3/4
- "Et incarnatus est..." Adagio, common time
- "Et resurrexit..." Allegro, 3/4
- "Sanctus" Andante maestoso, common time
- "Pleni sunt coeli et terra..." Allegro, cut common time
- "Benedictus" Allegro, cut common time
- "Agnus Dei" Adagio, common time
