Messe en sol majeur (Mass in G major), FP 89, is a missa brevis by Francis Poulenc.
Poulenc turned to sacred music first in 1937 when he composed the mass Messe en sol majeur.
He set all the parts of the Latin mass, with the exception of the Credo, in 1937, scored for a soprano soloist and a mixed choir a cappella.
[1] As he omitted the Credo, it is technically a missa brevis, in five movements:[2] The choral writing for unaccompanied choir has been described as of "cool purity".
[1] There are numerous recordings of the mass; the earliest may be a ca.1940 recording on 78 rpm of Les Chanteurs de Lyon (another name for Les Chœurs de Lyon, according to BNF) conducted by Ernest Bourmauck between 1934 and 1942[3] when he was succeeded by André Cluytens.
