Why did Giovanni Maria Artusi criticize Claudio Monteverdi’s music?

Giovanni Maria Artusi, a Bolognese theorist, criticized Claudio Monteverdi primarily for his use of advanced musical techniques, specifically his intense and prolonged use of dissonance.1

Artusi viewed these departures from traditional rules as violations of established musical conventions. In contrast, Monteverdi argued that his approach was part of a developing tradition known as the seconda prattica (second practice). He maintained that music should serve the text, stating that the expressive setting of words justified the abandonment of certain conventional musical devices to better "move the whole man". This debate highlighted a significant dichotomy between the modern, text-driven style and the older, strict polyphony championed by conservatives like Artusi.21
