1.1 Origins in the 17th century
1.1.1 The Roman Oratory and early forms
The oratorio emerged from the devotional meetings of the Oratory of St. Philip Neri in Rome during the late 16th century. These gatherings featured *laude spirituali* (spiritual songs), scripture readings, and sermons. By the early 1600s, composers began setting these dialogues to music, creating dramatic but unstaged works. The term “oratorio” originally referred to the prayer hall itself, then to the musical genre performed there. Early examples include Emilio de’ Cavalieri’s *Rappresentatione di Anima, et di Corpo* (1600), though it is often classified as a sacred opera or dialogue.
1.1.2 Italian oratorio (Carissimi, Scarlatti)
Giacomo Carissimi (1605–1674) established the classic Italian oratorio format. His works, such as *Jephte* (c. 1650), employed a *testo* (narrator), recitatives, arias, and choruses. The chorus acted as a commentator, a feature that became characteristic of the genre. Alessandro Scarlatti (1660–1725) further developed the form, composing over thirty oratorios with complex da capo arias and richer orchestration, notably in *Il primo omicidio*.
1.2 Baroque oratorio (c. 1650–1750)
1.2.1 German oratorio (Schütz, Bach)
In Germany, Heinrich Schütz (1585–1672) combined Italian influences with Lutheran tradition. His *Historia der Geburt Jesu Christi* (Christmas Oratorio, 1664) uses a continuous narrative with interpolated chorales and instrumental sinfonias. Johann Sebastian Bach (1685–1750) composed several oratorio-like works, including the *Christmas Oratorio* (1734–1735) and *Easter Oratorio* (c. 1725). Bach’s oratorios are structured as a series of cantatas for liturgical feast days, integrating chorales, recitatives, and elaborate choruses.
1.2.2 English oratorio (Handel)
1.2.2.1 Messiah and its influence
George Frideric Handel (1685–1759) invented the English oratorio after moving to London. His works, such as *Esther* (1718, revised 1732) and *Israel in Egypt* (1739), used English texts, large choruses, and dramatic narrative without staging. *Messiah* (1742) became the most famous oratorio in history, unusual for its structure: it tells no continuous story but meditates on Christ’s birth, passion, and resurrection through scriptural compilations. Its “Hallelujah” chorus epitomizes the power of the oratorio chorus. Handel’s success established the genre as a concert-hall staple, influencing later composers such as Haydn and Mendelssohn.
1.3 Classical and Romantic oratorio (c. 1750–1900)
1.3.1 Haydn’s *The Creation* and *The Seasons*
Joseph Haydn (1732–1809) composed *The Creation* (1798) after hearing Handel’s oratorios in London. Its libretto, based on the Book of Genesis and John Milton’s *Paradise Lost*, uses vivid tone painting (e.g., the chaos prelude, the sunrise). *The Seasons* (1801) is a secular oratorio depicting rural life and nature, with texts from James Thomson’s poem. Both works blend Classical formal clarity with Baroque choruses and Romantic expressive detail.
1.3.2 Mendelssohn’s *Elijah*
Felix Mendelssohn (1809–1847) revived the oratorio in the 19th century. *St. Paul* (1836) and *Elijah* (1846) are his major contributions. *Elijah* dramatizes the prophet’s story with powerful choruses (e.g., “He watching over Israel”) and dramatic recitatives. Mendelssohn’s use of Bachian counterpoint and Romantic orchestration made *Elijah* a landmark that influenced the English choral tradition.
1.3.3 French and other national traditions
France produced notable oratorios, including Hector Berlioz’s *L’Enfance du Christ* (1854), a tender, intimate work with a narrator and chamber-like scoring. In Italy, Gioachino Rossini’s *Mosè in Egitto* (1818, later revised) and Franz Liszt’s *Christus* (1866) expanded the genre. Late Romantic composers such as Antonín Dvořák (*Stabat Mater*, 1877) and Charles Gounod (*Mors et Vita*, 1885) continued the tradition, often using larger forces and programmatic elements.
1.4 20th century and contemporary oratorio
1.4.1 Modern works (Elgar, Stravinsky, Tippett)
Edward Elgar’s *The Dream of Gerontius* (1900) is a landmark of the late Romantic oratorio, setting Cardinal Newman’s poem about death and purgatory with richly chromatic music. Igor Stravinsky’s *Oedipus Rex* (1927) blends opera and oratorio, using a narrator and Latin text in a stylized, neo-classical format. Michael Tippett’s *A Child of Our Time* (1941) incorporates spirituals as a modern substitute for Bach chorales, addressing persecution and human suffering.
1.4.2 Secular and thematic oratorios
Composers increasingly wrote oratorios on non-religious subjects. William Walton’s *Belshazzar’s Feast* (1931) is a dramatic biblical work with jazz-influenced rhythms. Benjamin Britten’s *War Requiem* (1962) combines Latin Mass text with war poems—a hybrid of oratorio and requiem. In the late 20th century, John Adams created oratorios on contemporary themes: *El Niño* (2000) reimagines the Nativity story with Latin American poetry, and *The Gospel According to the Other Mary* (2012) focuses on Mary Magdalene. These works maintain the oratorio’s traditional structure while addressing modern social and spiritual questions.
2.1 Text and libretto
2.1.1 Biblical and sacred sources
Most oratorios draw on biblical narratives, especially Old Testament stories (e.g., Handel’s *Israel in Egypt*, Mendelssohn’s *Elijah*). The Gospel accounts of Christ’s passion also appear frequently (e.g., Bach’s *St. Matthew Passion*, though technically a passion, is closely related). Catholic and Protestant liturgical texts, such as the Magnificat *Te Deum*, are sometimes used. Librettists often compile verses from multiple scriptural books to create a cohesive dramatic arc.
2.1.2 Narrative and commentary
The libretto typically includes both narrative (recited by a narrator or soloist) and reflective commentary (expressed in arias and choruses). The chorus may take the role of a crowd (e.g., the Israelites in Handel’s *Judas Maccabaeus*) or a commentator on the action. This dual function distinguishes the oratorio from simple cantata or motet, giving it a dramatic but unstaged character.
2.2 Musical forms within an oratorio
2.2.1 Overture and instrumental sections
Oratorios usually open with an overture or instrumental sinfonia. In the Baroque period, this was often a French overture (slow–fast–slow) or an Italian sinfonia (fast–slow–fast). Later composers used more programmatic introductions (e.g., Haydn’s depiction of chaos in *The Creation*). Instrumental interludes, ritornellos, and descriptive passages (e.g., the storm in Haydn’s *The Seasons*) punctuate the work.
2.2.2 Recitative (secco and accompagnato)
Recitative carries the narrative forward. *Secco* recitative is accompanied by continuo (harpsichord and cello), used for rapid dialogue or exposition. *Accompagnato* recitative is supported by the full orchestra, employed for moments of high emotion or dramatic tension. Many oratorios alternate between the two types.
2.2.3 Aria and ensemble
Arias allow characters (or symbolic voices) to reflect emotionally on the story. Baroque arias often follow da capo form (ABA), while Classical and Romantic arias are more varied. Duets, trios, and other small ensembles appear, especially in later oratorios (e.g., the trio in Mendelssohn’s *Elijah*). These pieces are typically homophonic or imitative, contrasting with the thicker choral texture.
2.2.4 Chorus (fugal, homophonic, and programmatic)
The chorus is the central element of the oratorio. Fugal choruses (e.g., “And He shall purify” in Handel’s *Messiah*) display contrapuntal mastery. Homophonic choruses (e.g., “Lift up your heads”) provide solid, majestic statements. Programmatic choruses depict scenes such as battle (Handel’s *Joshua*), plagues (Israel in Egypt), or nature (Haydn’s *The Seasons*). The chorus often ends the oratorio with an elaborate fugue or a grand, homophonic finale.
2.3 Role of the orchestra
The orchestra supports all vocal forces, provides interludes, and creates mood. In Baroque oratorios, the orchestra is typically a string ensemble with continuo, sometimes augmented by oboes, bassoons, trumpets, and timpani for special effects. Classical and Romantic composers expanded the orchestra (e.g., Haydn’s use of trombones in *The Creation*, Berlioz’s large orchestra in *L’Enfance du Christ*). In modern works, the orchestra may include unconventional instruments or large percussion sections. The orchestra also plays a structural role, linking movements and providing tonal stability.
3.1 Concert performance conventions
Oratorios are traditionally performed in a concert setting—in churches, concert halls, or festival venues—with no costumes, sets, or acting. Singers stand at music stands or on risers; the conductor leads from the podium. This simplicity keeps the focus on the music and text. However, occasional semi-staged performances exist, where limited movement or lighting is added without full theatrical production.
3.2 Choir and soloist arrangements
The choir is usually placed behind or around the soloists, sometimes in a semicircle. Baroque oratorios often call for a relatively small choir (12–24 voices), but modern performances may use larger forces. Soloists sing their arias and recitatives from the front, often alternating roles. In narratively structured oratorios (like *Elijah*), soloists may take specific characters (Elijah, Obadiah, etc.), while in more contemplative works (like *Messiah*), they sing general reflections.
3.3 Differences from opera and cantata
Oratorio differs from opera in its lack of staging, costumes, and dramatic action. Opera is a theatrical genre; oratorio is a concert genre. Oratorio also emphasizes the chorus more heavily than most operas. The cantata is shorter, often for a single service, with less narrative scope. The passion (a dramatic setting of Christ’s crucifixion) is a subtype of oratorio but focuses on a single event with specific liturgical use.
4.1 Italian Baroque oratorio
4.1.1 Giacomo Carissimi (*Jephte*)
Carissimi’s *Jephte* (c. 1650) is a seminal work. It tells the biblical story of Jephthah’s vow and his daughter’s sacrifice. The work features a moving final chorus (“Plorate filiae Israel”) that laments the daughter’s fate. Carissimi’s use of the chorus as commentator and his expressive recitative became models for later oratorio writing.
4.1.2 Alessandro Scarlatti
Scarlatti composed around thirty oratorios, including *Il primo omicidio* (1707) about Cain and Abel. His works are characterized by fluent melody, structured arias, and orchestral independence. He refined the da capo aria and expanded the instrumental preludes.
4.2 German Baroque oratorio
4.2.1 Heinrich Schütz (*Christmas Oratorio*)
Schütz’s *Historia der Geburt Jesu Christi* (1664) is a landmark. It uses an evangelist narrator, dialogues, and chorales, with instrumental interludes (sinfonias) between scenes. The work is more austere than later oratorios, reflecting Schütz’s deep connection to the Lutheran liturgy.
4.2.2 Johann Sebastian Bach (*Christmas Oratorio*, *Easter Oratorio*)
Bach’s *Christmas Oratorio* (1734–1735) is a cycle of six cantatas for the Christmas season. It reuses music from earlier secular cantatas, adapted to sacred texts. The *Easter Oratorio* (c. 1725) is shorter, focusing on the Resurrection. Both works demonstrate Bach’s masterful integration of chorale tunes, recitative, and fugal choruses.
4.3 English oratorio
4.3.1 George Frideric Handel (*Messiah*, *Israel in Egypt*, *Judas Maccabaeus*)
Handel is the most prolific oratorio composer. *Messiah* (1742) is his best-known work, with a three-part structure: prophecy and birth, passion and resurrection, and final judgment. *Israel in Egypt* (1739) is notable for its extended choruses depicting the plagues and the crossing of the Red Sea. *Judas Maccabaeus* (1747) celebrates a military victory and became very popular in England. Handel’s oratorios established a template for the genre: dramatic narrative, heroic choruses, and accessible tunefulness.
4.4 Classical and Romantic oratorio
4.4.1 Joseph Haydn (*The Creation*)
*The Creation* (1798) is Haydn’s crowning achievement. In three parts (chaos, creation of the world, creation of mankind), it uses vivid orchestral tone painting (sunrise, animals, storms) and powerful choruses. The work was inspired by Handel’s oratorios and became a model for Classical-era choral writing.
4.4.2 Felix Mendelssohn (*Elijah*, *St. Paul*)
*Elijah* (1846) is Mendelssohn’s dramatic masterpiece. It recounts the prophet’s miracles, conflict with Baal worshippers, and ascension. Notable numbers include “Hear ye, Israel” (a soprano recitative and aria) and the double chorus “Behold, God the Lord passed by”. *St. Paul* (1836) covers Paul’s conversion and early ministry. Mendelssohn’s use of chorales and fugues gave these works a Baroque flavor within a Romantic style.
4.4.3 Hector Berlioz (*L’Enfance du Christ*)
Berlioz’s *L’Enfance du Christ* (1854) is a “sacred trilogy” on the flight into Egypt. It differs from earlier oratorios in its intimate, tender tone, chamber-like orchestration, and lyrical narration. The work includes the famous “Shepherd’s Farewell” chorus.
4.5 20th and 21st century oratorio
4.5.1 Edward Elgar (*The Dream of Gerontius*)
Elgar’s *The Dream of Gerontius* (1900) sets John Henry Newman’s poem about a dying man’s soul journey through judgment. It is divided into two parts: Gerontius’s death and his soul’s passage. The work uses leitmotifs and a richly chromatic Late Romantic language. Its dramatic chorus “Praise to the Holiest” is a concert favorite.
4.5.2 Igor Stravinsky (*Oedipus Rex*)
Stravinsky’s *Oedipus Rex* (1927) is a neo-classical work in Latin, with a narrator speaking the story. Though called an opera-oratorio, it is unstaged in many performances. The music is stark, rhythmically driven, and uses stylized forms (aria, chorus, and dramatic monologue).
4.5.3 John Adams (*El Niño*, *The Gospel According to the Other Mary*)
John Adams (b. 1947) has revitalized the oratorio for contemporary audiences. *El Niño* (2000) presents the Nativity story through a collage of biblical texts, medieval poetry, and works by Latin American women writers. It blends minimalism, folk rhythms, and multi-media elements. *The Gospel According to the Other Mary* (2012) focuses on Mary Magdalene and the Passion, using an expansive orchestral palette and jazz-influenced idioms.
5.1 Use in liturgy and concert halls
Oratorios have had a dual life: in church services (especially during Lent and Christmas) and in public concert halls. Baroque Lutheran oratorios (like Bach’s) were performed during specific liturgical seasons. Handel’s *Messiah* became a charity concert tradition in London, and later performances spread to churches and cathedrals worldwide. Today, oratorios are frequently programmed by professional and amateur choral societies, often as special seasonal events (e.g., *Messiah* sing-alongs).
5.2 Oratorio as a medium for biblical storytelling
The oratorio offers a powerful way to retell biblical stories without the distractions of theatrical staging. The music itself conveys emotion, drama, and divine transcendence. This medium allowed composers to explore religious narratives in depth, making them accessible to diverse audiences. Protestant and Catholic traditions alike embraced the oratorio for its educational and inspirational value.
5.3 Influence on later choral genres
The oratorio’s structure—combining narrative, reflection, and massed choral sound—influenced many later genres. The Romantic symphony with chorus (e.g., Beethoven’s Ninth) and the choral symphony (e.g., Mahler’s Second) borrowed its dramatic contrasts. The passion revived in the 20th century (e.g., Penderecki’s *St. Luke Passion*) also draws on oratorio traditions. Even secular dramatic works like William Walton’s *Belshazzar’s Feast* and Benjamin Britten’s *War Requiem* owe their formal clarity to the oratorio. The genre remains a vital, adaptable form for telling stories through words and music.
