 Granata’s later period pushes the instrument even further with extensive use of campanelas, notes in the upper register, and complex rhythms.Granata's fourth book - Soavi concenti (1659) - is one of the few sources to include pieces for the chitarra atiorbata, a five course instrument with seven open basses.Three of Granata's books also have works for ensemble.The pieces contained in Book IV call for a chamber ensemble of violin, guitar, and basso continuo, Book V for violin, viola, and guitar, and Book VII for guitar and basso continuo.
