The viol (also known as the viola da gamba) is any one of a family of bowed, fretted and stringed musical instruments developed in the mid-late 15th century and used primarily in the Renaissance and Baroque periods. The viol family is related to and descends primarily from the Renaissance vihuela, a plucked instrument that preceded the guitar. Viols are different in several respects from instruments of the violin family.

Vihuelists began playing their flat-edged instruments with a bow in the second half of the 15th century. Within two or three decades, this led to the evolution of an entirely new and dedicated bowed string instrument that retained many of the features of the original plucked vihuela: a flat back, sharp waist-cuts, frets, thin ribs (initially), and an identical tuning—hence its original name, vihuela de arco; arco is Spanish for "bow".

An influence in the playing posture has been credited to the example of Moorish rabab players.

Viols most commonly had six strings, although many 16th-century instruments had five or even four strings. Viols were (and are) strung with gut strings of lower tension than on the members of the violin family, let alone the steel strings mostly used there today. Gut strings produce a sonority far different from steel, the former generally described as softer and sweeter. Around 1660, gut or silk core strings overspun with copper wire first became available; these were then used for the lowest-pitched bass strings on viols, and on many other string instruments as well.

Marin Marais (31 May 1656, Paris – 15 August 1728, Paris) was a French composer and viol player. He studied composition with Jean-Baptiste Lully, often conducting his operas, and with master of the bass viol Monsieur de Sainte-Colombe for 6 months. He was hired as a musician in 1676 to the royal court of Versailles. He did quite well as court musician, and in 1679 was appointed "ordinaire de la chambre du roy pour la viole", a title he kept until 1725.

He was a master of the basse de viol, and the leading French composer of music for the instrument. He wrote five books of 'Pièces de viole' (1686-1725) for the instrument, generally suites with basso continuo. These were quite popular in the court, and for these he was remembered in later years as he who "founded and firmly established the empire of the viol" (Hubert Le Blanc, 1740). His other works include a book of Pièces en trio (1692) and four operas (1693-1709), Alcyone (1706) being noted for its tempest scene.

Titon du Tillet included Marais in Le Parnasse françois, making the following comments on two of his pieces, Le Labyrinthe, perhaps inspired by the labyrinth of Versailles, and La Gamme:

Jordi Savall i Bernadet (Catalan pronunciation: [ˈʒɔrði səˈβaʎ]; born January 14, 1942, in Igualada, Catalonia) is a Catalan viol player, conductor and composer. He has been one of the major figures in the field of Western early music since the 1970s, largely responsible for bringing the viol (viola da gamba) back to life on the stage. His characteristic repertory ranges from Medieval to Renaissance and Baroque music, though he has occasionally ventured into the classical or even the romantic period.

Savall's musical training started at the age of six in the school choir of his native town (1947–55). After completion of training at the Barcelona Conservatory of Music (1959–65), he specialised in early music, collaborating with Ars Musicae Barcelona of Enric Gispert and studying under August Wenzinger at the Schola Cantorum Basiliensis in Basel, Switzerland (1968–70). In 1974 he succeeded Wenzinger as professor of viola da gamba at the Schola Cantorum Basiliensis.

In 1974 he formed the ensemble Hespèrion XX (known since 2000 as Hespèrion XXI), together with the soprano Montserrat Figueras (his wife, who died in 2011), Lorenzo Alpert and Hopkinson Smith. Hespèrion XX favoured a style of interpretation characterised by great musical vitality and, at the same time, ultimate historical accuracy.

Georg Philipp Telemann (14 March 1681 – 25 June 1767) was a German Baroque composer and multi-instrumentalist. Almost completely self-taught in music, he became a composer against his family's wishes. After studying in Magdeburg, Zellerfeld, and Hildesheim, Telemann entered the University of Leipzig to study law, but eventually settled on a career in music. He held important positions in Leipzig, Żary, Eisenach, and Frankfurt before settling in Hamburg in 1721, where he became musical director of the city's five main churches. While Telemann's career prospered, his personal life was always troubled: his first wife died only a few months after their marriage, and his second wife had extramarital affairs and accumulated a large gambling debt before leaving Telemann.

Telemann was one of the most prolific composers in history (at least in terms of surviving oeuvre) and was considered by his contemporaries to be one of the leading German composers of the time—he was compared favorably both to his friend Johann Sebastian Bach, who made Telemann the Godfather and namesake of his son Carl Philipp Emanuel, and to George Frideric Handel, whom Telemann also knew personally. Telemann's music incorporates several national styles: French, Italian, and Polish. He remained at the forefront of all new musical tendencies and his music is an important link between the late Baroque and early Classical styles.
