One of the defining features of the new Baroque style was the so-called “trio sonata ideal.” In this, musical texture became stratified between a bass and two upper parts. Nowhere is this ideal more obviously seen than in the trio sonata, which, along with opera, was one of the defining genres of the Baroque style. This program will explore the evolution of the trio sonata throughout the Baroque period, in works by Bach, Antonio Bertali, Dario Castello, Arcangelo Corelli, Jean-Marie Leclair, Biagio Marini, Henry Purcell, and Luigi Rossi. The program will also present early vocal works for two singers and continuo by Claudio Monteverdi, showing how the trio sonata ideal operated in all genres, not just instrumental music.
