(Sebastian de), an eminent French musician. In the former part of his life he had been prebendary and chapel-master of the cathedral church of Strasbourg; but afterwards became grand-chaplain, and also maître de chapelle in the cathedral of Meaux. There is extant of his a work entitled Prodromus musicalis. He was author also of a very useful book, entitled Dictionnaire de musique, printed at Amsterdam, in folio, 1703; and afterwards at the same place in octavo, without a date. At the end of this book is a catalogue of authors ancient and modern, to the amount of 900, who have written on music; divided into classes, wherein are interspersed many curious observations of the author relating to the history of music. By Mr Boivin's Catalogue général des livres de musique for the year 1729, it appears that Broffard was the author of two sets of motets, as also of nine Lecons de Tenebres therein mentioned. It seems that these several publications were at a time when the author was far advanced in years; for Walther takes notice, that in the Mercure Galante, he is mentioned as an abbe and composer, so early as the year 1678.
