Of Le Jeune's sacred music, a total of 347 psalm settings, thirty-eight sacred chansons, eleven motets, and a mass setting have survived. His secular output included 146 airs, most of which were in the style of "musique mesurée," as well as sixty-six chansons, and forty-three Italian madrigals. In addition, three instrumental fantasias were published posthumously in 1612, as well as some works for lute. He was fortunate in that his copious manuscripts were published after his death: his friend, the equally gifted and prolific composer Jacques Mauduit, was fated to have most of his music lost.
