Usper probably settled in Venice before 1586 when he was students of Gabrieli. The main constituents of his orchestration, strings and trombones, betray his tendencies towards his teacher’s impact. His name was originally Sponga but he transformed it in commitment to the official in his confraternity, a business which he offered throughout his lifestyle. Usper also offered several churches in Venice including St. Salvatore and St. Mark’s. On the previous he was the organist as well as the last mentioned an helper to Grillo. He constructed a number of the first ensemble canzones in Venice with one sinfonia including passages for recorder and chittarone performed against the ritornello from the strings. Usper acquired a keen feeling of textual appearance in his vocal compositions and instrumental buildings.
