A talented violinist, composer and teacher, Taglietti was one of the few Italian instrumental composers of the early eighteenth century. He taught for the Jesuits in Brescia from 1702, if not before, and can be included in the company of Corelli and his brother Luigi. These composers were all important in the development of the concerto but Giulio limited the number of movements to three or four also demonstrating a preference for solos scored in a single treble voice when he scored solo parts. Giulio also had a preference for concerto grossi as contrasted with concertos scored for solo instruments. Taglietti composed in various instrumental genres including sonatas, concertos and divertimenti.
