Barcelona Mass

Together with the Messe de Nostre Dame by Guillaume de Machaut and those of Toulouse, Tournai and the Sorbonne, it is one of the earliest preserved complete polyphonic musical settings of the Ordinary of the Mass.

It is believed to belong to the repertoire of the Papal court at Avignon and is also linked to the chapel of King Martin I of Aragon.

It is preserved in a single manuscript kept in the Biblioteca de Catalunya in Barcelona (ms. 971), where it was found in 1925 by the musicologist Higinio Anglés.

It consists of the usual five parts, the Kyrie, Gloria, Credo, Sanctus and Agnus Dei.

The Gloria and Credo have also been independently preserved as standalone pieces in other sources.
