Which Baroque composer is associated with the use of basso continuo, ritornello, and castrati singers?

• A. Giulio Caccini
• B. Claudio Monteverdi
• C. Giacomo Carissimi
• D. Henry Purcell

Answer: (B)

In Baroque opera, three threads come together: a continuous bass foundation with basso continuo, the use of recurring instrumental refrains that frame vocal sections (ritornello), and the casting of castrati for leading male roles. Claudio Monteverdi embodies all of these in a way that defines the period’s operatic practice. He built his dramatic works around a strong continuo texture that underpins recitative and arias, giving the music a flexible yet sustained harmonic spine. He also employs instrumental interludes and repeated musical figures that function like ritornello episodes, helping to unify scenes and provide expressive contrast. And in Italian opera of his time, castrati were the favored singers for heroic roles, a practice Monteverdi leveraged to achieve dramatic and vocal extremes that shaped the sound of his operas. This combination—continuo-based harmony, ritornello-like structure, and prominent castrato roles—points to Monteverdi as the figure most closely associated with all three traits.
