Although classed as a ''missa brevis'' (brief mass), the inclusion of trumpets in the scoring makes it a ''missa brevis et solemnis''.<ref name=Sadie/>

The autograph manuscript of the mass is preserved in the Berlin State Library.

==Background==

The mass is often referred to as the '''''Spaur Mass''''',<ref name=Sadie/><ref name=Kenyon>{{cite book|title=The Pegasus Pocket Guide to Mozart|first=Nicholas|last=Kenyon|author-link=Nicholas Kenyon|year=2006|url=https://archive.org/details/pegasuspocketgui0000keny_t6l6|url-access=registration|page=[https://archive.org/details/pegasuspocketgui0000keny_t6l6/page/264 264]|isbn=978-1-933648-23-1 }}</ref> although this is misleading; Leopold Mozart wrote in 1778 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.<ref>{{cite book|title=Mozart|first=Robert|last=Gutnam|year=2011|publisher=Random House |isbn=9781446477076|url=https://books.google.com/books?id=gu-kvXUiVd0C}}</ref> The original score of this mass was discovered in the archives of the Cathedral of Brixen in 2007; this provides another link to the Spaur family, some of whom held power in the Bishopric of Brixen.<ref>{{cite web|url=http://www.provincia.bz.it/usp/285.asp?_cate_id=10556&aktuelles_action=4&aktuelles_article_id=172500|title=Trovata a Bressanone la partitura originale della Spaur-Messe di Mozart|date=15 June 2007|access-date=1 March 2013|publisher=Provincia autonoma di Bolzano|language=Italian|trans-title=Original score of Mozart's Spaur Mass found in Bressanone}}</ref>

An alternative nickname, '''''Piccolomini Mass''''', is speculated to refer to the brevity of the mass;<ref>{{cite book|title=The Compleat Mozart: A Guide to the Musical Works of Wolfgang Amadeus Mozart|first1=Neal|last1=Zaslaw|author-link1=Neal Zaslaw|first2=William|last2=Cowdery|year=1990|publisher=W. W. Norton & Company |isbn=9780393028867|url=https://books.google.com/books?id=CChN90GGcQQC}}</ref> it does not appear to have any connection with the Piccolominis, a Sienese noble family.

This is one of three masses Mozart composed in November and December 1776, all set in C major, including the Credo Mass (K. 257) and the Organ Solo Mass (K. 259).<ref>{{cite book|title=Mozart: His Character, His Work|first=Alfred|last=Einstein|author-link=Alfred Einstein|year=1945|url=https://archive.org/details/mozarthischaract0000eins_n9b0/page/n7/mode/2up|url-access=registration|via=Internet Archive|page=338|publisher=Oxford University Press}}</ref>
