Jhan Gero (also Ghero, Giero; first name rendered occasionally as Jehan, Jan) (fl.
He was a practitioner of the note nere madrigal style during its period of popularity in the 1540s, and also wrote didactic music, probably intended for teaching beginning singers.
[1] Nothing is known about his early life, but it is inferred that he was from northern Europe, perhaps Flanders, as were many musicians of the time who were working in Italy.
He seems to have risen to prominence through the efforts of the Venetian publishing company run by Antonio Gardano and Girolamo Scotto; they may have paid him to make arrangements of works by others, as indicated by his first publication, in 1541, which contained Italian madrigals and French chansons, originally for three or four voices, however in this case arranged for only two singers each.
After this year, during which he published two books of motets, no further records of his life or activities have yet come to light.
