These motets all present particular traits of Jean-Philippe Rameau's writing: from the astonishing austerity of the motet to 5 vocal parts and basso continuo, Laboravi clamans inserted into his famous treatise of harmony, to the extreme delicacy of the 'In convertendo many times redesigned for the Spiritual Concert and whose Jean Duron, scientific director of the Center of Baroque Music of Versailles and publisher of the present work, makes us discover the stages of composition. The other two motets are only known to us by late copies that reflect a different practice of music. Here again, Jean Duron proposes a restoration of the works more in line with the time of their creation, leaving to the interpreters the freedom to choose one or the other version. These pieces were available only in the version made by Camille Saint-Saëns at Editions Durand. Thanks to this new edition, these magnificent works can find their way back to concerts. In addition to the exceptional qualities of these pieces for soloists, choirs and orchestra, soloists for women's and men's voices are among the finest in French religious music. We note in particular the first issue of Quam dilecta tabernacula, of the same motet numbers 3, and enim pass, and 6, Domine Deus virtutum, and in the In convertendo the number 3, Converte Domine captivitatem nostram which are part of the fund of essential directory of singers. The volume contains a bilingual (French / English) introduction illustrated with several examples in facsimile, the four motets of Rameau, critical notes and appendices. The introduction of Jean Duron returns to the catalog of religious works by Jean-Philippe Rameau, the description of the sources used for publishing and the principles that allowed the restoration of the works.
