Robert was born around 1430 in England, but no details of his early life are known, and little can be reconstructed with certainty except for his involvement with the Burgundian court. From 1457 until 1476 he was a clerc or chappellain in the chapel choir. By 1460 he was a priest, since he was given that title Messire in chapel document. He passed away in 1479.
His work was highly regarded at the time, but only secular vocal music, all Rondeaux for three voices, survive.
Most of Morton's music survives in sources from the Continent, Eight pieces survive, all rondeaux. 
''Il sera pour vous conbatu/L'homme armé which was used by many early Renaissance composers as a cantus firmus for the Mass.
Le souvenir de vous me tue was exceedingly famous, and copies of this piece were widely disseminated in Europe.
Cousine trop vous abusés
Mon bien ma joyeux
N'aray je jamais mieulx que j'ay
Paracheve ton entreprise
Plus j'ay le monde
Que pourroit plus faire une dame
