René Jacobs (born 30 October 1946, Ghent) is a Belgian (Flemish) musician. He came to fame as a countertenor but in recent years has become renowned as a conductor of Baroque and early Classical opera.

Jacobs began his musical career as a boy chorister at the Cathedral of Ghent. Later he studied classical philology at the University of Ghent while continuing to sing in Brussels and in The Hague.

The Kuijken brothers, Gustav Leonhardt and Alfred Deller all encouraged him to pursue a career as a countertenor, and he quickly became known as one of the best of his time. He recorded a large amount of less-known Baroque music by such composers as Antonio Cesti, d'India, Ferrari, Marenzio, Lambert, Guédron, William Lawes and others. He also sang in much-acclaimed recordings of the major works of Bach (such as the St Matthew Passion led by Gustav Leonhardt and Philippe Herreweghe).

More recently, as a conductor, Jacobs has recorded numerous operas and sacred and secular works of the 16th, 17th and 18th centuries. His recording of Mozart's The Marriage of Figaro is especially renowned, having won such awards as Gramophone's Record of the Year for 2004, "Le Monde de la Musique"'s Choc of the Year for 2004, a Grammy Award for "Best Opera recording of 2005", and two Midem Classical Awards in 2004. Other award-winning recordings include George Frideric Handel’s Rinaldo (Cannes Classical Award, 2004), and Joseph Haydn’s Die Jahreszeiten (Diapason d’Or of 2005). The partial discography below lists some of the many other awards won by Jacobs' recordings. His recordings and work have won numerous awards, including the Grammy Award for "Best Opera", Gramophone 's "Record of the Year", the "III Premio Traetta 2011", and numerous European awards. His recording of Mozart's Magic Flute was Record of the Year at the inaugural International Classical Music Awards in April 2011.

Franz Joseph Haydn (  /ˈdʒoʊzəf ˈhaɪdən/; German pronunciation: [ˈjoːzɛf ˈhaɪdən] ( listen); 31 March 1732 – 31 May 1809), known as Joseph Haydn, was an Austrian composer, one of the most prolific and prominent composers of the Classical period. He is often called the "Father of the Symphony" and "Father of the String Quartet" because of his important contributions to these forms. He was also instrumental in the development of the piano trio and in the evolution of sonata form.

A lifelong resident of Austria, Haydn spent much of his career as a court musician for the wealthy Esterházy family on their remote estate. Isolated from other composers and trends in music until the later part of his long life, he was, as he put it, "forced to become original". At the time of his death, he was one of the most celebrated composers in Europe.

Joseph Haydn was the brother of Michael Haydn, himself a highly regarded composer, and Johann Evangelist Haydn, a tenor. He was also a close friend of Wolfgang Amadeus Mozart and a teacher of Ludwig van Beethoven.

Emilio de' Cavalieri (ca. 1550–March 11, 1602) was an Italian composer, producer, organist, diplomat, choreographer and dancer at the end of the Renaissance era. His work, along with that of other composers active in Rome, Florence and Venice, was critical in defining the beginning of the musical Baroque era. A member of the Roman School of composers, he was an influential early composer of monody, and wrote what is usually considered to be the first oratorio.

Cavalieri was born in Rome of an aristocratic and musical family. He was the son of Tommaso de' Cavalieri (ca. 1509–1587), the close friend of Michelangelo. He probably received his early training there, and was working as an organist and music director in the period from 1578 to 1584. He spent much of his time in Rome as an organiser of Lenten oratorios. While in Rome he became associated with Cardinal Ferdinando de' Medici.

Henry Purcell ( /ˈpɜrsəl/; 10 September 1659 (?)– 21 November 1695), was an English composer. Although incorporating Italian and French stylistic elements into his compositions, Purcell's legacy was a uniquely English form of Baroque music. He is generally considered to be one of the greatest English composers; no other native-born English composer approached his fame until Edward Elgar.

Purcell was born in St Ann's Lane Old Pye Street, Westminster. Henry Purcell Senior, whose older brother Thomas Purcell (d. 1682) was also a musician, was a gentleman of the Chapel Royal and sang at the coronation of King Charles II of England. Henry the elder had three sons: Edward, Henry and Daniel. Daniel Purcell (d. 1717), the youngest of the brothers, was also a prolific composer who wrote the music for much of the final act of The Indian Queen after Henry Purcell's death. Henry Purcell's family lived just a few hundred yards west of Westminster Abbey from the year 1659 and onward.

After his father's death in 1664, Purcell was placed under the guardianship of his uncle who showed him great affection and kindness. Thomas was himself a gentleman of His Majesty's chapel, and arranged for Henry to be admitted as a chorister. Henry studied first under Captain Henry Cooke (d. 1672),Master of the Children, and afterwards under Pelham Humfrey (d. 1674), Cooke's successor. Henry was a chorister in the Chapel Royal until his voice broke in 1673, when he became assistant to the organ-builder John Hingston, who held the post of keeper of wind instruments to the King.
