Azzolino Bernardino Della Ciaia (circa 1590–1640) was an Italian composer and musician of the late Renaissance and early Baroque periods, primarily associated with the genre of vocal music, particularly sacred and secular choral works. Little is known about his early life, but he was active in Venice, a hub for musical innovation during his time. Della Ciaia is best known for his collections of madrigals and sacred music, including "Madrigali a cinque voci" (Madrigals for five voices), published in 1619. His compositions often feature intricate polyphony and expressiveness, reflecting the transition from the Renaissance style to the early Baroque emphasis on emotional depth and clarity of text. His impact on music is significant in the context of the development of the madrigal form, influencing subsequent composers by bridging traditional polyphonic techniques with emerging Baroque practices. While he may not be as widely recognized as contemporaries like Monteverdi, Della Ciaia's contributions to the evolving landscape of vocal music during this transformative period remain noteworthy.
