(b La Tessoualle, Maine-et-Loire, 6 June 1848; d Solesmes, 18 Jan. 1930). French scholar. Believing that an understanding of medieval chant could be achieved only by a comparative study of its early sources, he initiated Paléographie musicale, a series of facsimiles of medieval chant manuscripts. He became a monk of Solesmes in 1877, and later prior (1902–8). At first he assisted Joseph Pothier in preparing chant books, and took over from him as choirmaster in 1889. Pothier's preference was for late medieval chant of the 14th century, whereas Mocquereau's interest was in the reconstruction of the ‘original’. Many of his ideas were superseded by those of Eugène Cardine.
