Within the court of Leonello, Pietrobono became a successful musician and favoured within the Ferrareses court, in the court of Leonello. He would perform his music on a lute. Pietrobono's first appearance was in the early court of Leonello d' Este of 1441. In terms of personal fame, Pietrobono stands above musicians such as Corrado and many other Ferrarese musicians. During the first year of Leonello's reign, Pietrobono-who was in his mid-twenties—was given the sum of twenty gold ducats/coins by Leonello which was the sum that was apparently the common payment that the Este family had use in the past, with such people as Dufay in 1437. By the mid-1440s Pietrobono had a substantial increase in pay and salary during the reign of Leonello.
