This new score by Toulouse maître de musique Bernard-Aymable Dupuy (1707–1789) reveals a new aspect of the composer’s musical career and of the musical heritage of the Midi-Pyrénées region. Together with the motet Exurge Domine, it complements the already-published motet Nisi quia Dominus erat in nobis.

Dupuy’s first appointment was in 1744 as maître de musique at Saint-Bertrand-de-Comminges Cathedral. This mass, from the Marcorelles manuscript, was composed using only basso continuo to support the voices of the six soloists and the four-part choir. The musical writing, lighter in texture than that of the motets, is highly effective: of particular note are the general joyfulness of the mass and the expressivity created by the weaving of two high voices (dessus) over an ostinato in the Crucifixus.
