Stile concitato (rather Genere concitato[1]) or "agitated style" is a Baroque style developed by Claudio Monteverdi with effects such as having rapid repeated notes and extended trills as symbols of bellicose agitation or anger.
Kate Van Orden points out a precedent in Clément Janequin's "La Guerre" (1528).
"[4]Monteverdi developed the musical style of stile concitato to represent the human emotion of agitation.
He considered Il combattimento di Tancredi e Clorinda, one of the pieces from Madrigali guerrieri, et amorosi, to be the first instance of stile concitato.
[5] Stile concitato is represented musically in Il combattimento di Tancredi e Clorinda through the rapid repetition of sixteenth notes.
