Oratorio

Oratorio is a large vocal-orchestral work, usually unstaged, with soloists, chorus, orchestra or continuo, and a dramatic or sacred text. Its sound is opera-adjacent but concert-anchored: recitatives move narrative, arias focus character or meditation, and choruses deliver communal, theological, or monumental force.

The genre developed from Roman devotional oratories and early Baroque sacred drama, then Handel transformed it into a public English concert genre with biblical and moral subjects. Bach's Passions, Haydn's Creation and Seasons, Mendelssohn's Elijah and St Paul, Elgar's Dream of Gerontius, Walton's Belshazzar's Feast, and later Britten, Tippett, Adams, MacMillan, and Saariaho extended oratorio beyond church into civic memory, politics, and modern spirituality.
