Most of his secular songs were in French, and for three voices, and most survive from Italian manuscripts. Most are rondeaux, and most are in duple meter. One of his songs, "Helas que pourra devenir", was extraordinarily famous, and was the second-most-widely distributed song in manuscript sources of the third quarter of the 15th century ("De tous biens plaine", by Hayne van Ghizeghem, was the first). It is unusual among songs of the time in using very close imitation, and it seems to have initiated a trend. David Fallows, writing in the New Grove, hypothesises that it may have originated as an instrumental fantasy.
