Venus est pas cent mille noms
Guillaume Costeley (1530-1606)
Musique, by Guillaume Costeley, 1570
Costeley was part of Baïf’s Academie de musique et de poésie, and coincidentally born in the same part of the Auvergne as Bertrand and Boni. Unlike them he followed a purely musical career, as royal organist when Charles IX was on the throne, and is famous for his many chansons. Not so many of them were to texts by Ronsard, though – only 6 of the 100 or so surviving songs.
A remarkably homophonic song, not many accidentals, and really no chromaticism at all – a nice easy piece to transcribe. The recorded extract, the opening half-dozen lines, demonstrates this neatly.
Here are the reproductions I used, taken from the ground-breaking article Ronsard et les musiciens du XVIe Siècle published by Charles Comte & Paul Laumonier in the Revue d’Histoire littéraire de la France 1900:
