L'Orfeo (SV 318) (), or La favola d'Orfeo , is a late Renaissance/early Baroque favola in musica, or opera, by Claudio Monteverdi, with a libretto by Alessandro Striggio. It is based on the Greek legend of Orpheus, and tells the story of his descent to Hades and his fruitless attempt to bring his dead bride Eurydice back to the living world. It was written in 1607 for a court performance during the annual Carnival at Mantua. While Jacopo Peri's Dafne is generally recognised as the first work in the opera genre, and the earliest surviving opera is Peri's Euridice, L'Orfeo is the earliest that is still regularly performed.

By the early 17th century the traditional intermedio—a musical sequence between the acts of a straight play—was evolving into the form of a complete musical drama or "opera". Monteverdi's L'Orfeo moved this process out of its experimental era and provided the first fully developed example of the new genre. After its initial performance the work was staged again in Mantua, and possibly in other Italian centres in the next few years. Its score was published by Monteverdi in 1609 and again in 1615. After the composer's death in 1643 the opera went unperformed for many years, and was largely forgotten until a revival of interest in the late 19th century led to a spate of modern editions and performances. At first these performances tended to be concert (unstaged) versions within institutes and music societies, but following the first modern dramatised performance in Paris, in 1911, the work began to be seen in theatres. After the Second World War many recordings were issued, and the opera was increasingly staged in opera houses, although some leading venues resisted it. In 2007, the quatercentenary of the premiere was celebrated by performances throughout the world.

In his published score Monteverdi lists around 41 instruments to be deployed, with distinct groups of instruments used to depict particular scenes and characters. Thus strings, harpsichords, and recorders represent the pastoral fields of Thrace with their nymphs and shepherds, while heavy brass illustrates the underworld and its denizens. Composed at the point of transition from the Renaissance era to the Baroque, L'Orfeo employs all the resources then known within the art of music, with particularly daring use of polyphony. The work is not orchestrated as such; in the Renaissance tradition instrumentalists followed the composer's general instructions but were given considerable freedom to improvise.

Historical background

Claudio Monteverdi, born in Cremona in 1567, was a musical prodigy who studied under Marc'Antonio Ingegneri, the maestro di cappella (head of music) at Cremona Cathedral. After training in singing, string playing and composition, Monteverdi worked as a musician in Verona and Milan until, in 1590 or 1591, he secured a post as suonatore di vivuola (viola player) at Duke Vincenzo Gonzaga's court at Mantua. Through ability and hard work Monteverdi rose to become Gonzaga's maestro della musica (master of music) in 1601.

Vincenzo Gonzaga's particular passion for musical theatre and spectacle grew from his family connections with the court of Florence. Towards the end of the 16th century innovative Florentine musicians were developing the intermedio—a long-established form of musical interlude inserted between the acts of spoken dramas—into increasingly elaborate forms. Led by Jacopo Corsi, these successors to the renowned Camerata were responsible for the first work generally recognised as belonging to the genre of opera: Dafne, composed by Corsi and Jacopo Peri and performed in Florence in 1598. This work combined elements of madrigal singing and monody with dancing and instrumental passages to form a dramatic whole. Only fragments of its music still exist, but several other Florentine works of the same period—Rappresentatione di Anima, et di Corpo by Emilio de' Cavalieri, Peri's Euridice and Giulio Caccini's identically titled Euridice—survive complete. These last two works were the first of many musical representations of the Orpheus myth as recounted in Ovid's Metamorphoses, and as such were direct precursors of Monteverdi's L'Orfeo.

The Gonzaga court had a long history of promoting dramatic entertainment. A century before Duke Vincenzo's time the court had staged Angelo Poliziano's lyrical drama La favola di Orfeo, at least half of which was sung rather than spoken. More recently, in 1598 Monteverdi had helped the court's musical establishment produce Giovanni Battista Guarini's play Il pastor fido, described by theatre historian Mark Ringer as a "watershed theatrical work" which inspired the Italian craze for pastoral drama. On 6 October 1600, while visiting Florence for the wedding of Maria de' Medici to King Henry IV of France, Duke Vincenzo attended the premiere of Peri's Euridice. It is likely that his principal musicians, including Monteverdi, were also present at this performance. The Duke quickly recognised the novelty of this new form of dramatic entertainment, and its potential for bringing prestige to those prepared to sponsor it.Ringer, p. 16

Creation

Libretto

Among those present at the Euridice performance in October 1600 was a young lawyer and career diplomat from Gonzaga's court, Alessandro Striggio, son of a well-known composer of the same name. The younger Striggio was himself a talented musician; as a 16-year-old, he had played the viol at the wedding festivities of Duke Ferdinando of Tuscany in 1589. Together with Duke Vincent's two young sons, Francesco and Fernandino, he was a member of Mantua's exclusive intellectual society, the , which provided the chief outlet for the city's theatrical works. It is not clear at what point Striggio began his libretto for L'Orfeo, but work was evidently under way in January 1607. In a letter written on 5 January, Francesco Gonzaga asks his brother, then attached to the Florentine court, to obtain the services of a high quality castrato from the Grand Duke's establishment, for a "play in music" being prepared for the Mantuan Carnival.

Striggio's main sources for his libretto were Books 10 and 11 of Ovid's Metamorphoses and Book Four of Virgil's Georgics. These provided him with the basic material, but not the structure for a staged drama; the events of acts 1 and 2 of the libretto are covered by a mere 13 lines in the Metamorphoses. For help in creating a dramatic form, Striggio drew on other sources—Poliziano's 1480 play, Guarini's Il pastor fido, and Ottavio Rinuccini's libretto for Peri's Euridice. The musicologist Gary Tomlinson remarks on the many similarities between Striggio's and Rinuccini's texts, noting that some of the speeches in L'Orfeo "correspond closely in content and even in locution to their counterparts in L'Euridice". The critic Barbara Russano Hanning writes that Striggio's verses are less subtle than those of Rinuccini, although the structure of Striggio's libretto is more interesting. Rinuccini, whose work had been written for the festivities accompanying a Medici wedding, was obliged to alter the myth to provide a "happy ending" suitable for the occasion. By contrast, because Striggio was not writing for a formal court celebration he could be more faithful to the spirit of the myth's conclusion, in which Orfeo is killed and dismembered by deranged maenads or "Bacchantes". He chose, in fact, to write a somewhat muted version of this bloody finale, in which the Bacchantes threaten Orfeo's destruction but his actual fate is left in doubt.

The libretto was published in Mantua in 1607 to coincide with the premiere and incorporated Striggio's ambiguous ending. However, Monteverdi's score published in Venice in 1609 by Ricciardo Amadino shows an entirely different resolution, with Orpheus transported to the heavens through the intervention of Apollo. According to Ringer, Striggio's original ending was almost certainly used at the opera's premiere, but there is no doubt that Monteverdi believed the revised ending was aesthetically correct. The musicologist Nino Pirrotta argues that the Apollo ending was part of the original plan for the work, but was not staged at the premiere because the small room which hosted the event could not contain the theatrical machinery that this ending required. The Bacchantes scene was a substitution; Monteverdi's intentions were restored when this constraint was removed.

Composition

When Monteverdi composed L'Orfeo he had a thorough grounding in theatrical music. He had been employed at the Gonzaga court for 16 years, much of it as a performer or arranger of stage music, and in 1604 he had written the ballo Gli amori di Diane ed Endimone for the 1604–05 Mantua Carnival. The elements from which Monteverdi constructed his first opera score—the aria, the strophic song, recitative, choruses, dances, dramatic musical interludes—were, as conductor Nikolaus Harnoncourt has pointed out, not created by him, but "he blended the entire stock of newest and older possibilities into a unity that was indeed new". Musicologist Robert Donington writes similarly: "[The score] contains no element which was not based on precedent, but it reaches complete maturity in that recently developed form ... Here are words as directly expressed in music as [the pioneers of opera] wanted them expressed; here is music expressing them ... with the full inspiration of genius."

Monteverdi states the orchestral requirements at the beginning of his published score, but in accordance with the practice of the day he does not specify their exact usage. At that time it was usual to allow each interpreter of the work freedom to make local decisions, based on the orchestral forces at their disposal. These could differ sharply from place to place. Furthermore, as Harnoncourt points out, the instrumentalists would all have been composers and would have expected to collaborate creatively at each performance, rather than playing a set text. Another practice of the time was to allow singers to embellish their arias. Monteverdi wrote plain and embellished versions of some arias, such as Orfeo's "Possente spirto", but according to Harnoncourt "it is obvious that where he did not write any embellishments he did not want any sung".

Each act of the opera deals with a single element of the story, and each ends with a chorus. Despite the five-act structure, with two sets of scene changes, it is likely that L'Orfeo conformed to the standard practice for court entertainments of that time and was played as a continuous entity, without intervals or curtain descents between acts. It was the contemporary custom for scene shifts to take place in sight of the audience, these changes being reflected musically by changes in instrumentation, key and style.

Instrumentation

For the purpose of analysis the music scholar Jane Glover has divided Monteverdi's list of instruments into three main groups: strings, brass and continuo, with a few further items not easily classifiable. The strings grouping is formed from ten members of the violin family (viole da brazzo), two double basses (contrabassi de viola), and two kit violins (violini piccoli alla francese). The viole da brazzo are in two five-part ensembles, each comprising two violins, two violas and a cello. The brass group contains four or five trombones (sackbuts), three or four trumpets and two cornetts. The continuo forces include two harpsichords (duoi gravicembani), a double harp (arpa doppia), three chitarroni, two pipe organs (organi di legno), three bass viola da gamba, and a regal or small reed organ. Outside of these groupings are two recorders (flautini alla vigesima secunda), and possibly one or more citterns—unlisted by Monteverdi, but included in instructions relating to the end of act 4.
