Although a substantial amount of his music has survived in several sources, his actual name is not known with certainty.
The second possibility is that "le Petit" may be the same as Jean Lepetit, the singing master at Langres Cathedral between 1506 and 1510.
Baltazar died in 1502, Lepetit after 1529; stylistically the music of le Petit suggests composition in the first two decades of the 16th century.
He preferred clear harmonies, a texture occasionally broken by long duets, and contrasting sections in triple meter, somewhat blending the styles of Févin and Mouton.
The chansons are light and open in texture, foreshadowing the developments in the genre later in the century.
