Jacopo Peri (Zazzerino) (20 August 156112 August 1633) was an Italian composer and singer of the transitional period between the Renaissance and Baroque styles, and is often called the inventor of opera.
 He wrote the first work to be called an opera today, "Dafne" (around 1597), and also the first opera to have survived to the present day, "Euridice" (1600).
L'Orfeo (SV 318) (] ), sometimes called 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.
Dafne is the earliest known work that, by modern standards, could be considered an opera.
 The libretto by Ottavio Rinuccini survives complete; the mostly-lost music was completed by Jacopo Peri, but at least two of the six surviving fragments are by Jacopo Corsi.
 "Dafne" was first performed during Carnival of 1598 (1597 old style) at the Palazzo Corsi.
Euridice is an opera in a prologue and one act by the Italian composer Giulio Caccini.
 The libretto, by Ottavio Rinuccini, had already been set by Caccini's rival Jacopo Peri in 1600.
 Caccini's version of "Euridice" was first performed at the Pitti Palace, Florence on 5 December 1602.
 Caccini hurriedly prepared the score for the press and published it six weeks before Peri's version appeared.
Jacopo Corsi (17 July 1561 – 29 December 1602) was an Italian composer of the late Renaissance and early Baroque and one of Florence's leading patrons of the arts, after only the Medicis.
 His best-known work is "Dafne" (1597/98), whose score he wrote in collaboration with Jacopo Peri.
 Six fragments of the score have survived, two by Corsi and four by Peri.
 The libretto, by Ottavio Rinuccini, has survived intact.
 Despite priority quibbles at the time, Dafne is generally accepted as the first opera.
Euridice (also Erudice or Eurydice) is an opera by Jacopo Peri, with additional music by Giulio Caccini.
 It is the earliest surviving opera, Peri's earlier "Dafne" being lost.
 (Caccini wrote his own "Euridice" even as he supplied music to Peri's opera, published this version before Peri's was performed, in 1600, and got it staged two years later.)
 The libretto by Ottavio Rinuccini is based on books X and XI of Ovid's "Metamorphoses"
These lists show the audio and visual recordings of the opera "L'Orfeo" by Claudio Monteverdi.
 The opera was first performed in Mantua in 1607, at the court of Duke Vincenzo Gonzaga, and is one of the earliest of all operas.
 The first recording of "L'Orfeo" was issued in 1939, a freely adapted version of Monteverdi's music edited by Giacomo Benvenuti, given by the orchestra of La Scala Milan conducted by Ferrucio Calusio.
 In 1949 the Berlin Radio Orchestra under Helmut Koch recorded the complete opera, on long-playing records (LPs).
 The advent of LP recordings was, as Harold Schonberg later wrote, an important factor in the postwar revival of interest in Renaissance and Baroque music, and from the mid-1950s recordings of "L'Orfeo" have been issued on many labels.
 Koch's landmark version was reissued in 1962, when it was compared unfavourably with others that had by then been issued.
 The 1969 recording by Nicholas Harnoncourt and the Vienna Concentus Musicus, using Harnoncourt's edition based on period instruments, was praised for "making Monteverdi's music sound something like the way he imagined".
 In 1981 Siegfried Heinrich, with the Early Music Studio of the Hesse Chamber Orchestra, recorded a version which re-created the original Striggio libretto ending, adding music from Monteverdi's 1616 ballet "Tirsi e Clori" for the Bacchante scenes.
 Among more recent recordings, that of Emmanuelle Haïm has been praised for its dramatic effect.
 The 21st century has seen the issue of an increasing number of recordings on DVD.
Claudio Giovanni Antonio Monteverdi (] ; 15 May 1567 (baptized) – 29 November 1643) was an Italian composer, string player and choirmaster.
 A composer of both secular and sacred music, and a pioneer in the development of opera, he is considered a crucial transitional figure between the Renaissance and the Baroque periods of music history.
The Stattkus-Verzeichnis (SV) is a catalogue of the musical compositions of the Italian composer Claudio Monteverdi.
 The catalogue was published in 1985 by Manfred H. Stattkus ("Claudio Monteverdi: Verzeichnis der erhaltenen Werke").
 A free, basic second edition of the catalogue is available online.
