Viol

The viol, or viola da gamba, 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 and bass 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.)

History

Vihuelists began playing their flat-topped, originally plucked, 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 vihuela: e.g, a flat back, sharp waist-cuts, frets, thin ribs initially, and identical tuning—hence its original name, vihuela de arco; arco is Spanish for "bow". An influence on the playing posture has been credited to the example of Moorish rabab players.

However, Stefano Pio (2012) argues that a re-examination of documents in light of new data indicates an origin different than the vihuela de arco from Aragon. According to Pio, the viol had its origins in Venice, and evolved independently there. He asserts it was implausible that the vihuela de arco underwent such a rapid evolution by Italian rather than Venetian instrument makers. Nonetheless, a ten-year span brought the birth and diffusion in Italy of a new family of instruments (viola da gamba, or viols). These comprised instruments of different sizes, some as large as the famous violoni—as 'big as a man'—mentioned by Prospero Bernardino in 1493.

Pio also notes that the fifth string of the viola da gamba is uniquely called a bordone (drone)—both in the manuscript of the early 15th-century music theorist Antonius de Leno, and in the treatises of the Venetian Silvestro Ganassi dal Fontego and Giovanni Maria Lanfranco. However, it is not a drone and is played the same as the other strings. This inconsistency is justified, Pio argues, only by assuming the invention (in the latter 15th century) of a larger instrument derived from the medieval violetta, which gradually added more strings to allow greater extension to the low register. The fifth string was incorporated into the neck. This was surpassed by a sixth string (basso) which fixed the lower sound produced by the instrument. Pio's view was: the origin of the viola da gamba is tied to the evolution of the smaller violetta, or vielle, which was originally fitted with a fifth-string "drone"; and the name 'stuck' even after it ceased to perform this function.

Construction

Viols most commonly have six strings, although many 16th-century instruments had only four or five strings, and during the 17th century in France, some bass viols featured a seventh lower string. Viols were (and are) strung with gut strings of lower tension than on the members of the violin family. Gut strings produce a sonority far different from steel, generally described as softer and sweeter. Around 1660 in Bologna, 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 many other string instruments as well. In 1664, a style of string incorporating a copper wire spun within the gut fibers, called a 'gimped' string, was introduced, mimicking the style of embroidery of the same name.

Viols are fretted like early guitars or lutes, using movable wrapped-around and tied-on gut frets. A low seventh string was supposedly added in France to the bass viol by Monsieur de Sainte-Colombe (c. 1640–1690), whose students included the French gamba virtuoso and composer Marin Marais. Also, the painting (1618) by Domenichino (1581–1641) shows what may be a seven-string viol.

Unlike members of the violin family, most of which are tuned in fifths, viols are usually tuned in fourths with a major third in the middle, mirroring the tuning employed on the vihuela de mano and lute during the 16th century and similar to that of the modern six-string guitar.

Viols were first constructed much like the vihuela de mano, with all surfaces, top, back, and sides made from flat slabs or pieces of joined wood, bent or curved as required. However, some viols, both early and later, had carved tops, similar to those more commonly associated with instruments of the violin family. The ribs or sides of early viols were usually quite shallow, reflecting more the construction of their plucked vihuela counterparts. Rib depth increased during the 16th century, finally coming to resemble the greater depth of the classic 17th-century pattern.

Viol bows

The bow is held underhand with the palm facing upward, similar to a German double bass bow grip, but away from the frog towards the balance point. The stick's curvature is generally convex as were violin bows of the period, rather than concave like a modern violin bow. The "frog" (which holds the bow hair and adjusts its tension) is also different from that of modern bows: whereas a violin bow frog has a "slide" (often made of mother of pearl), which pinches the hair and holds it flat and stationary across the frog, viol bows have an open frog that allows more movement of the hair. This facilitates a traditional playing technique where the performer uses one or two fingers of the bow hand to press the hair away from the bow stick. This dynamically increases bow hair tension to control articulation and inflection.

Different versions

Viols come in seven sizes: "pardessus de viole" (which is relatively rare, exclusively French and did not exist before the 18th century), treble (dessus in French), alto, tenor (in French taille), bass, great bass, and contrabass (the final two are often called violone, meaning large viol), the smaller one tuned an octave below the tenor (violone in G, sometimes called great bass or in French grande basse) and the larger one tuned an octave below the bass (violone in D, or the contrabass viol). This latter instrument is not to be confused with the double bass.

Their tuning alternates G and D instruments: pardessus in G, treble in D, tenor in G, bass in D (the seven-string bass was a French invention, with an added low A), small violone in G, large violone in D and the alto (between the treble and the tenor).

The treble has a size similar to a viola but with a deeper body; the typical bass is about the size of a cello. The pardessus and the treble were held vertically in the lap. The English made smaller basses known as division viols, and the still-smaller Lyra viol. The viola bastarda was a similar type of viol used in Italy for a virtuosic style of viol repertoire and performance. German consort basses were larger than the French instruments designed for continuo.

Tuning

The standard tuning of most viols is in fourths, with a major third in the middle (like the standard Renaissance lute tuning), or in fourths, with a major third in between the 2nd and 3rd strings (like a modern guitar). The following table shows the tunings that have been adopted at least somewhat widely during the 20th and 21st-century revival of the viols. (Lyra viol tunings are not included.)

Alternative tunings (called scordatura) were often employed, particularly in the solo lyra viol style of playing, which also made use of many techniques such as chords and pizzicato, not generally used in consort playing. An unusual style of pizzicato was known as a thump. Lyra viol music was also commonly written in tablature. There is a vast repertoire of this music, some by well-known composers and much by anonymous ones.

Much viol music predates the adoption of equal temperament tuning by musicians. The movable nature of the tied-on frets permits the viol player to make adjustments to the tempering of the instrument, and some players and consorts adopt meantone temperaments, which are more suited to Renaissance music. Several fretting schemes involve frets that are spaced unevenly to produce better-sounding chords in a limited number of keys. In some of these schemes, the two strands of the gut that form the fret are separated so that the player can finger a slightly sharper or flatter version of a note (for example G♯ versus A♭) to suit different circumstances.

Similar names and common confusions

The viola da gamba is occasionally confused with the viola, the alto member of the modern violin family and a standard member of both the symphony orchestra and string quartet. In the 15th century, the Italian word "viola" was a generic term used to refer to any bowed instrument, or fiddle. The word "viola" existed in Italy before the vihuela, or first viol, was brought from Spain. In Italy, "viola" was first applied to a braccio precursor to the modern violin, as described by Tinctoris (De inventione et usu musice, c. 1481–3), and then was later used to describe the first Italian viols as well. Depending on the context, the unmodified viola da braccio most regularly denoted either an instrument from the violin family, or specifically the viola (whose specific name was "alto de viola da braccio"). When Monteverdi called simply for "viole da braccio" in "Orfeo", the composer was requesting violas as well as treble and bass instruments. The full name of the viola, namely "alto de viola da braccio", was finally shortened to "viola" in some languages (e.g. English, Italian, Spanish) once viols became less common, while other languages picked some other part of the phrase to designate the instrument, e.g. "alto" in French and "Bratsche" in German (the latter derived from the Italian "braccio").
