The warlike spirit and the grandeur of Ferdinandís Court was highly reinforced by the use of the trumpet and its military repertoire, as it appears in Cesare Bendinelliís (1614) and Girolamo Fantiniís (1638) playing methods of the instrument, where we can trace pieces that almost certainly form the source of inspiration for Valentiniís
. It is possible that Monteverdi might have heard Valentiniís compositions, as well as that he already knew Gabrieliís instrumental pieces and the military signals of the trumpet. His decision to imitate them is probably connected to his ambitions concerning his professional and financial status. However, the existence of the madrigal Non piý guerra
in Valentiniís book of
1621 proves that Monteverdi was the first to occupy himself with the problematic of the passions, which rule the warriorís soul in battle and their expression in terms of music.
