This list provides a guide to opera composers, as determined by their presence on a majority of compiled lists of significant opera composers. (See the "Lists Consulted" section for full details.) The composers run from Jacopo Peri, who wrote the first ever opera in late 16th century Italy, to John Adams, one of the leading figures in the contemporary operatic world. The brief accompanying notes offer an explanation as to why each composer has been considered major. Also included is a section about major women opera composers, compiled from the same lists. For an introduction to operatic history, see opera. The organisation of the list is by birthdate.

Major opera composers 1550–1699 Jacopo Peri (1561–1633) Florentine who composed both the first opera ever, Dafne (1598), and the first surviving opera, Euridice (1600).Viking Opera Guide p. 768 Claudio Monteverdi (1567–1643) Generally regarded as the first major opera composer.Orrey p. 18 In Orfeo (1607) he blended Peri's experiments in opera with the lavish spectacle of the intermedi.Professor Tim Carter in Viking Opera Guide (p. 678) writes: "Monteverdi's recitative owes much to Peri ... However Orfeo has much broader roots. There are many references to the tradition of the Florentine intermedi: the spectacular stage effects, the mythological subject matter, the allegorical figures, the number and scoring of the instruments and the extended choruses". See also Carter, writing about the intermedi in The Oxford Illustrated History of Opera (p. 4): "rich display and erudite symbolism made the intermedi an ideal projection of princely magnificence". Later, in Venice in the 1640s, he helped make opera a commercially viable form with Il ritorno d'Ulisse in patria and L'incoronazione di Poppea, one of the earliest operas in the present-day operatic repertoire. Francesco Cavalli (1602–1676) Amongst the most important of Monteverdi's successors, Cavalli was a major force in spreading opera throughout Italy and also helped introduce it to France. His Giasone was " the most popular opera of the 17th century".Viking Opera Guide p. 189 Jean-Baptiste Lully (1632–1687) In close collaboration with the librettist Philippe Quinault, Lully founded the tradition of tragédie en musique,Orrey p. 35 combining singing, dance and visual spectacle, which would remain the most prestigious French operatic genre for almost a hundred years. Cadmus et Hermione (1673) is often regarded as the first example of French opera. Henry Purcell (1659–1695) First English operatic composer of significance. His masterwork is Dido and Aeneas.Orrey p. 55 Alessandro Scarlatti (1660–1725) Key figure in the development of opera seria, Scarlatti claimed to have composed over 100 operas, of which La Griselda is a notable example.Viking Opera Guide p. 942 Johann Christoph Pepusch (1667–1752) Arranger of the first English ballad opera, the biting political satire, The Beggar's Opera.Viking Opera Guide p. 343 Jean-Philippe Rameau (1683–1764) Most important French opera composer of the 18th century. Following in the genre established by Lully,Orrey p. 40 he endowed his works with a great richness of invention. Rameau's musical daring provoked great controversy in his day, but he was an important influence on Gluck. George Frideric Handel (1685–1759) Handel's opera serie set the standard in his day.Orrey p. 59 Handel composed a series of over 40 operas.

1700–1799

Giovanni Battista Pergolesi (1710–1736) Though Pergolesi also composed opera serias, his most influential work was the short opera buffa, La serva padrona.Oxford Companion to Music, p. 783 Christoph Willibald Gluck (1714–1787) Was a key figure in the transformation of Baroque into Classical opera, paving the way for Mozart, though his influence stretched much further into the 19th century, with both Berlioz and Wagner acknowledging their debt to him. In his reform operas from Orfeo ed Euridice onwards, he sought to throw off the formal conventions of opera seria and write music of "beautiful simplicity" (his own words).Orrey p. 85 Joseph Haydn (1732–1809) Haydn wrote nineteen operas including several comic operas and singspiels.Manual of Music: Its History, Biography and Literature Page 96 Wilber M. Derthick · 1888 Giovanni Paisiello (1740–1816) Italian composer who wrote the first opera to include Beaumarchais' character Figaro as a main character, as well as writing a substantial number of other operas, some of them in St. Petersburg. André Grétry (1741–1813) Liège (present-day Belgium) composer crucial to the development of French opéra comique, whose simplicity of musical style and sophisticated dramaturgy were immensely popular, as well as linking pre-revolutionary rococo comedy to the later romantic style. Domenico Cimarosa (1749–1801) Italian composer most famous for the opera buffa, Il matrimonio segreto, which forms a bridge between the comedies of Mozart and Rossini.Viking Opera Guide pp. 216–218 Antonio Salieri (1750–1825) Italian composer who was a major contributor to and shaper of Viennese musical life from 1770 to 1820, he also composed successful operas in Italy and Paris, and won admiration from German operagoers as a composer who, in the words of one contemporary critic, ‘could bind all the power of German music to the sweet Italian style’.Jane Schatkin Hettrick, John A. Rice. "Salieri, Antonio" in The New Grove Dictionary of Music and Musicians. His opera Europa riconosciuta was composed for the inauguration of La Scala. Among his other most successful operas were Les Danaïdes, Axur, re d'Ormus (the Italian version of French Tarare) and Falstaff.

Master of orchestral colour and atmosphere, Weber was never well served by his librettists, and only one of his works, Der Freischütz, is performed with any frequency. Though he died young, his influence on later German composers, especially Wagner, was immense. Giacomo Meyerbeer (1791–1864) The archetypal composer of French grand opera, Meyerbeer's huge extravaganzas such as Les Huguenots and Le prophète were immensely popular in their day.Oxford Illustrated History of Opera pp. 146–150 Gioachino Rossini (1792–1868) Links bel canto with grand opera.

Among his most famous works are Nabucco, Rigoletto, Il Trovatore, La traviata, Don Carlos, Aida, and Otello.Orrey pp. 137–147 Charles Gounod (1818–1893) Wrote lyrical operas on literary themes, including Roméo et Juliette and Mireille.
