Jean Gilles (c. 1668 – 1705) was a prominent French composer of the Baroque era, best known for his contributions to sacred music, particularly within the context of the Roman Catholic liturgy. His genre primarily encompasses motets and other choral works, characterized by rich polyphony and expressive harmonies. Gilles's most notable works include his collection of motets published in 1690, which showcased his skill in blending traditional French styles with the emerging Italian influences of the time. One of his renowned pieces is the "Messe de Requiem," which is often cited for its emotional depth and intricate choral writing. His impact on music is significant in the development of French sacred choral music, influencing subsequent generations of composers. Gilles's ability to convey emotion through music helped pave the way for the later evolution of French liturgical compositions. Although not as widely recognized today as some of his contemporaries, his work remains an important part of Baroque choral repertoire, reflecting the stylistic transitions of the period.
