Giacomo Carissimi (baptized 18 April 1605 – 12 January 1674) was an Italian composer and music teacher. He is one of the most celebrated masters of the early Baroque or, more accurately, the Roman School of music. Carissimi established the characteristic features of the Latin oratorio and was a prolific composer of motets and cantatas. He was highly influential in musical developments in north European countries through his pupils and the wide dissemination of his music.
Carissimi's exact birthdate is not known, but it was probably in 1604 or 1605 in Marino near Rome, Italy. Of his early life almost nothing is known. Giacomo’s parents, Amico (1548–1633, a cooper by trade) and Livia (1565–1622), were married on 14 May 1595 and had four daughters and two sons; Giacomo was the youngest.
Nothing is known of his early musical training. His first known appointments were at Tivoli Cathedral, under the maestri di cappella Aurelio Briganti Colonna, Alessandro Capece and Francesco Manelli; from October 1623 he sang in the choir, and from October 1624 to October 1627 he was the organist. In 1628 Carissimi moved north to Assisi, as maestro di cappella (chapel master) at the Cathedral of San Rufino. In 1628 he obtained the same position at the church of Sant'Apollinare belonging to the Collegium Germanicum in Rome, which he held until his death. This was despite him receiving several offers to work in very prominent establishments, including an offer to take over from Claudio Monteverdi at San Marco di Venezia in Venice. In 1637 he was ordained a priest. He seems to have never left Italy at all during his entire lifetime. He died in 1674 in Rome.
Carissimi's successor as maestro di cappella at the Collegium Germanicum in 1686 described him as tall, thin, very frugal in his domestic affairs, with very noble manners towards his friends and acquaintances, and prone to melancholy.
The great achievements generally ascribed to Carissimi are the further development of the recitative, introduced by Monteverdi, which is highly important to the history of dramatic music; the further development of the chamber cantata, by which Carissimi superseded the concertato madrigals which had themselves replaced the madrigals of the late Renaissance; and the development of the oratorio, of which he was the first significant composer.
