The madrigal, Renaissance Italy’s great secular song, taught music to listen to poetry. From Arcadelt’s dying swan to Gesualdo’s anguished chromaticism, Monteverdi’s daring dissonances, and the sunlit fa-las of Morley and Weelkes, this essay traces how composers made sighs fall, flames leap, and lovers expire in sound. Along the way, it explores word painting, the poets of Petrarch’s lineage, and why these intimate a cappella part-songs still reward attentive listeners more than four centuries later.
