A fantasia (Italian: [fantaˈziːa]; also English: fantasy, fancy, fantazy, phantasy; German: Fantasie, Phantasie; French: fantaisie) is a musical composition with roots in improvisation. The fantasia, like the impromptu, seldom follows the textbook rules of any strict musical form.

Orlando Gibbons (bapt. 25 December 1583 – 5 June 1625) was an English composer and keyboard player who was one of the last masters of the English Virginalist School and English Madrigal School. The best known member of a musical family dynasty, by the 1610s he was the leading composer and organist in England, with a career cut short by his untimely death in 1625. As a result, Gibbons's oeuvre was not as large as that of his contemporaries, like the elder William Byrd, but he made considerable contributions to many genres of his time. Musicologists characterize his music as exemplifying the transition from the Renaissance to the Baroque periods. Gibbons was born into a musical family where his father was a wait, his brothers—Edward, Ellis and Ferdinand—were musicians and Orlando was expected to follow the tradition. It is not known under whom he studied, although it may have been with Edward or Byrd, but he almost certainly studied the keyboard in his youth. Irrespective of his education, he was musically proficient enough to be appointed an unsalaried member of the Chapel Royal in May 1603 and a full-fledged gentleman of the Chapel Royal as junior organist by 1605. By 1606, he had graduated from King's College, Cambridge, with a Bachelor of Music degree. Throughout his professional career, Gibbons maintained good relations with many important people of the English court. King James I and Prince Charles were supportive patrons and others, such as Sir Christopher Hatton, even became close friends. Along with Byrd and John Bull, Gibbons was the youngest contributor to the first printed collection of English keyboard music, Parthenia, and published other compositions in his lifetime, notably, the First Set of Madrigals and Motets (1612) which includes the best known English madrigal: The Silver Swan. Other important compositions include "This is the Record of John", the eight-part full anthem "O Clap Your Hands Together" and two settings of Evensong. The most important position achieved by Gibbons was his appointment in 1623 as the organist at Westminster Abbey, which he held for two years until his death. Gibbons developed Byrd's foundations of the English madrigal, full and verse anthems, and by doing so he exerted significant influence on subsequent English composers. This generation included his oldest son Christopher, who would teach John Blow, Pelham Humfrey and Henry Purcell, the English pioneer of the Baroque era. After his death he was primarily remembered a composer of sacred music. Since the early music revival however, increased attention has come to his other compositions, with his keyboard works championed by Glenn Gould, while his madrigals and viol fantasies are popular among early music ensembles. By the 21st-century almost all of his music has been published and recorded.

The viola da gamba (Italian: [ˈvjɔːla da (ɡ)ˈɡamba, viˈɔːla -]), or viol, or informally gamba, is a bowed and fretted string instrument that is played da gamba (i.e. "on the leg"). It is distinct from the later violin, or viola da braccio; and it is any one of the earlier viol family of bowed, fretted, and stringed instruments with hollow wooden bodies and pegboxes where the tension on the strings can be increased or decreased to adjust the pitch of each of the strings. Although treble, tenor and bass were most commonly used, viols came in different sizes, including pardessus (high treble, developed in 18th century), treble, alto, small tenor, tenor, bass and contrabass (called violone). These members of the viol family are distinguished from later bowed string instruments, such as the violin family, by both appearance and orientation when played—as typically the neck is oriented upwards and the rounded bottom downwards to settle on the lap or between the knees. The viola da gamba uses the alto clef. Seven and occasionally eight frets made of "stretched gut" are tied on the fingerboard around the instrument's neck. Frets tied in this manner—instead of permanently fixed as on a guitar—allow for fine-tuning of the instrument. (Frets enable the performer to stop the strings more cleanly, improve consistency of intonation and lend the stopped notes a tone that better matches the open strings.) Viols first appeared in Spain and Italy in the mid-to-late 15th century, and were most popular in the Renaissance and Baroque (1600–1750) periods. Early ancestors include the Arabic rebab and the medieval European vielle, but later, more directly possible ancestors include the Venetian viole and the 15th- and 16th-century Spanish vihuela, a six-course plucked instrument tuned like a lute (and also like a present-day viol) that (at the time) looked like, but was quite distinct from, the four-course guitar (an earlier chordophone). It should also be mentioned that the Arabic rebab originally comes from a Persian instrument called rubāb. Although bass viols superficially resemble cellos, viols are different in several respects from instruments of the violin family: the viol family has flat rather than curved backs, sloped rather than rounded shoulders, c holes rather than f holes, and five to seven rather than four strings. Additional differences include tuning strategy—in fourths, with a third in the middle, rather than in fifths (similar to a lute)—the presence of frets, and underhand rather than overhand bow grip. A modern player of the viol is commonly known as a gambist, violist , or violist da gamba. Notably, "violist" is a homograph of the word commonly used since the mid-20th century to refer to a player of the viola, which can cause confusion in written/printed texts when not clear from the context.

William Byrd (; c. 1540 – 4 July 1623) was an English Renaissance composer. Considered among the greatest composers of the Renaissance, he had a profound influence on composers both from his native country and on the Continent. He is often considered along with John Dunstaple and Henry Purcell as one of England's most important composers of early music. Byrd wrote in many of the forms current in England at the time, including various types of sacred and secular polyphony, keyboard (the so-called Virginalist school), and consort music. He produced sacred music for Anglican services, but during the 1570s became a Roman Catholic, and wrote Catholic sacred music later in his life.

The compositions of Orlando Gibbons (1583–1625) include works in virtually every genre of the Elizabethan and Jacobean eras. Due to his sudden and early death, Gibbons' output was not as large as that of his older contemporary William Byrd, but he still managed to produce various secular and sacred polyphonic vocal works, including consort songs, services, more than 40 full anthems and verse anthems, a set of 20 madrigals as well as at least 20 keyboard works and various instrumental ensemble pieces including nearly 30 fantasies for viols. He is well known for the 5-part verse anthem This is the Record of John, the 8-part full anthem O Clap Your Hands Together, 2 settings of Evensong and what is often thought to be the best known English madrigal: The Silver Swan.
