Viola

The viola (/viˈoʊlə/ vee-OH-lə,^[1] Italian: [ˈvjɔːla, viˈɔːla]) is a string instrument of the violin family, and is usually bowed when played. Violas are slightly larger than violins, and have a lower and deeper sound. Since the 18th century, it has been the middle or alto voice of the violin family, between the violin (which is tuned a perfect fifth higher) and the cello (which is tuned an octave lower).^[2] The strings from low to high are typically tuned to C₃, G₃, D₄, and A₄.

In the past, the viola varied in size and style, as did its names. The word viola originates from the Italian language. The Italians often used the term viola da braccio, meaning, literally, 'of the arm'. "Brazzo" was another Italian word for the viola, which the Germans adopted as Bratsche. The French had their own names: cinquiesme was a small viola, haute contre was a large viola, and taile was a tenor. Today, the French use the term alto, a reference to its range.

The viola was popular in the heyday of five-part harmony, up until the eighteenth century, taking three lines of the harmony and occasionally playing the melody line. Music for the viola differs from most other instruments in that it primarily uses the alto clef. When viola music has substantial sections in a higher register, it switches to the treble clef to make it easier to read.

The viola often plays the "inner voices" in string quartets and symphonic writing, and it is more likely than the first violin to play accompaniment parts. The viola occasionally plays a major, soloistic role in orchestral or chamber music. Examples include the symphonic poem Don Quixote, by Richard Strauss, the 13th Quartet by Dmitri Shostakovich, and a symphony with a main viola line: Harold en Italie, by Hector Berlioz. In the earlier part of the 20th century, more composers began to write for the viola, encouraged by the emergence of specialized soloists such as Lionel Tertis and William Primrose. English composers Arthur Bliss, Edwin York Bowen, Benjamin Dale, Frank Bridge, Benjamin Britten, Rebecca Clarke and Ralph Vaughan Williams all wrote substantial chamber and concert works. Many of these pieces were commissioned by, or written for, Tertis. William Walton, Bohuslav Martinů, Tōru Takemitsu, Tibor Serly, Alfred Schnittke, and Béla Bartók have written well-known viola concertos. The concerti by Bartók, Paul Hindemith, Carl Stamitz, Georg Philipp Telemann, and Walton are considered major works of the viola repertoire. Hindemith, who was a violist, wrote a substantial amount of music for viola, including the concerto Der Schwanendreher.

The viola is similar in material and construction to the violin. A full-size viola's body is between 25 and 100 mm (1 and 4 in) longer than the body of a full-size violin (i.e., between 38 and 46 cm [15–18 in]), with an average length of 41 cm (16 in). Small violas typically made for children typically start at 30 cm (12 in), which is equivalent to a half-size violin. For a child who needs a smaller size, a fractional-sized violin is often strung with the strings of a viola.^[3] Unlike the violin, the viola does not have a standard full size. The body of a viola would need to measure about 51 cm (20 in) long to match the acoustics of a violin, however it can only be played vertically like a Cello, hence the name Vertical viola.^[4] For centuries, viola makers have experimented with the size and shape of the viola, often adjusting proportions or shape to make a lighter instrument with shorter string lengths, but with a large enough sound box to retain the viola sound. Prior to the eighteenth century, violas had no uniform size. Large violas (tenors) were designed to play the lower register viola lines or second viola in five part harmony depending on instrumentation. A smaller viola, nearer the size of the violin, was called an alto viola. It was more suited to higher register writing, as in the viola 1 parts, as their sound was usually richer in the upper register. Its size was not as conducive to a full tone in the lower register.

Several experiments have intended to increase the size of the viola to improve its sound and harmony. Hermann Ritter's viola alta, which measured about 48 cm (19 in), was intended for use in Wagner's operas.^[5] The Tertis model viola, which has wider bouts and deeper ribs to promote a better tone, is another slightly "nonstandard" shape that allows the player to use a larger instrument. Many experiments with the acoustics of a viola, particularly increasing the size of the body, have resulted in a much deeper tone, making it resemble the tone of a cello. Since many composers wrote for a traditional-sized viola, particularly in orchestral music, changes in the tone of a viola can have unintended consequences upon the balance in ensembles.

One of the most notable makers of violas of the twentieth century was Englishman A. E. Smith, whose violas are sought after and highly valued. Many of his violas remain in Australia, his country of residence, where during some decades the violists of the Sydney Symphony Orchestra had a dozen of them in their section.

More recent (and more radically shaped) innovations have addressed the ergonomic problems associated with playing the viola by making it shorter and lighter, while finding ways to keep the traditional sound. These include the Otto Erdesz "cutaway" viola, which has one shoulder cut out to make shifting easier;^[6] the "Oak Leaf" viola, which has two extra bouts; viol-shaped violas such as Joseph Curtin's "Evia" model, which also uses a moveable neck and maple-veneered carbon fibre back, to reduce weight:^[7] violas played in the same manner as cellos (see vertical viola); and the eye-catching "Dalí-esque" shapes of both Bernard Sabatier's violas in fractional sizes—which appear to have melted—and David Rivinus' Pellegrina model violas.^[8]

Other experiments that deal with the "ergonomics vs. sound" problem have appeared. The American composer Harry Partch fitted a viola with a cello neck to allow the use of his 43-tone scale, called the "adapted viola". Luthiers have also created five-stringed violas,^[9] which allow a greater playing range.

A person who plays the viola is called a violist or a viola player. The technique required for playing a viola has certain differences compared with that of a violin, partly because of its larger size: the notes are spread out further along the fingerboard and often require different fingerings. The viola's less responsive strings and the heavier bow warrant a somewhat different bowing technique, and a violist has to lean more intensely on the strings.^[10]

The viola is held in the same manner as the violin; however, due to its larger size, some adjustments must be made to accommodate. The viola, just like the violin, is placed on top of the left shoulder between the shoulder and the left side of the face (chin). Because of the viola's size, violists with short arms tend to use smaller-sized instruments for easier playing. The most immediately noticeable adjustments that a player accustomed to playing the violin has to make are to use wider-spaced fingerings. It is common for some players to use a wider and more intense vibrato in the left hand, facilitated by employing the fleshier pad of the finger rather than the tip, and to hold the bow and right arm further away from the player's body. A violist must bring the left elbow further forward or around, so as to reach the lowest string, which allows the fingers to press firmly and so create a clearer tone. Different positions are often used, including half position.

The viola is strung with thicker gauge strings than the violin.^[11] This, combined with its larger size and lower pitch range, results in a deeper and mellower tone. However, the thicker strings also mean that the viola responds to changes in bowing more slowly. Practically speaking, if a violist and violinist are playing together, the violist must begin moving the bow a fraction of a second sooner than the violinist. The thicker strings also mean that more weight must be applied with the bow to make them vibrate.

The viola's bow has a wider band of horsehair than a violin's bow, which is particularly noticeable near the frog (or heel in the UK). Viola bows, at 70–74 g (2.5–2.6 oz), are heavier than violin bows (58–61 g [2.0–2.2 oz]). The profile of the rectangular outside corner of a viola bow frog generally is more rounded than on violin bows.

The viola's four strings are normally tuned in fifths: the lowest string is C (an octave below middle C), with G, D, and A above it. This tuning is exactly one fifth below the violin,^[12] so that they have three strings in common—G, D, and A—and is one octave above the cello.

Each string of a viola is wrapped around a peg near the scroll and is tuned by turning the peg. Tightening the string raises the pitch; loosening the string lowers the pitch. The A string is normally tuned first, to the pitch of the ensemble: generally 400–442 Hz. The other strings are then tuned to it in intervals of fifths, usually by bowing two strings simultaneously. Most violas also have adjusters—fine tuners, particularly on the A string that make finer changes. These adjust the tension of the string via rotating a small knob above the tailpiece. Such tuning is generally easier to learn than using the pegs, and adjusters are usually recommended for younger players and put on smaller violas, though pegs and adjusters are usually used together. Some violists reverse the stringing of the C and G pegs, so that the thicker C string does not turn so severe an angle over the nut, although this is uncommon.

Small, temporary tuning adjustments can also be made by stretching a string with the hand. A string may be tuned down by pulling it above the fingerboard, or tuned up by pressing the part of the string in the pegbox. These techniques may be useful in performance, reducing the ill effects of an out-of-tune string until an opportunity to tune properly.

The tuning C–G–D–A is used for the great majority of all viola music.^[13] However, other tunings are occasionally employed, both in classical music, where the technique is known as scordatura, and in some folk styles. Mozart, in his Sinfonia Concertante for Violin, Viola and Orchestra in E♭, wrote the viola part in D major, and specified that the violist raises the strings in pitch by a semitone. He probably intended to give the viola a brighter tone so the rest of the ensemble would not overpower it. Tertis, in his transcription of the Elgar cello concerto, wrote the slow movement with the C string tuned down to B♭, enabling the viola to play one passage an octave lower.

A renewal of interest in the viola by performers and composers in the twentieth century led to increased research devoted to the instrument. Paul Hindemith and Vadim Borisovsky made an early attempt at an organization, in 1927, with the Violists' World Union. But it was not until 1968, with the creation of the Viola-Forschungsgesellschaft, now the International Viola Society (IVS), that a lasting organization took hold. The IVS now consists of twelve chapters around the world, the largest being the American Viola Society (AVS), which publishes the Journal of the American Viola Society. In addition to the journal, the AVS sponsors the David Dalton Research Competition and the Primrose International Viola Competition.

The 1960s also saw the beginning of several research publications devoted to the viola, beginning with Franz Zeyringer's, Literatur für Viola, which has undergone several versions, the most recent being in 1985. In 1980, Maurice Riley produced the first attempt at a comprehensive history of the viola, in his History of the Viola, which was followed with the second volume in 1991. The IVS published the multi-language Viola Yearbook from 1979 to 1994, during which several other national chapters of the IVS published respective newsletters. The Primrose International Viola Archive at Brigham Young University houses the greatest amount of material related to the viola, including scores, recordings, instruments, and archival materials from some of the world's greatest violists.^[14]

There are few well-known viola virtuoso soloists, perhaps because little virtuoso viola music was written before the twentieth century. Pre-twentieth century viola players of note include Stamitz, Rolla, Antonio Rolla, Chrétien Urhan, Casimir Ney, Louis van Waefelghem, and Ritter. Important viola pioneers from the twentieth century were Tertis, William Primrose, Hindemith, Théophile Laforge, Cecil Aronowitz, Maurice Vieux, Borisovsky, Lillian Fuchs, Dino Asciolla, Frederick Riddle, Walter Trampler, Ernst Wallfisch, Csaba Erdélyi, the only violist to ever win the Carl Flesch International Violin Competition, and Emanuel Vardi, the first violist to record the 24 Caprices by Paganini on viola. Many noted violinists have publicly performed and recorded on the viola as well, among them Eugène Ysaÿe, Yehudi Menuhin, David Oistrakh, Pinchas Zukerman, Maxim Vengerov, Julian Rachlin, James Ehnes, and Nigel Kennedy.

Among the great composers, several preferred the viola to the violin when they were playing in ensembles, the most noted being Ludwig van Beethoven, Bach^[27] and Mozart. Other composers also chose to play the viola in ensembles, including Joseph Haydn, Franz Schubert, Mendelssohn, Dvořák, and Benjamin Britten. Among those noted both as violists and as composers are Rebecca Clarke and Hindemith. Contemporary composers and violists Kenji Bunch, Scott Slapin, and Lev Zhurbin have written a number of works for viola.

Amplification of a viola with a pickup, an instrument amplifier (and speaker), and adjusting the tone with a graphic equalizer can make up for the comparatively weaker output of a violin-family instrument string tuned to notes below G3. There are two types of instruments used for electric viola: regular acoustic violas fitted with a piezoelectric pickup and specialized electric violas, which have little or no body.^[28] While traditional acoustic violas are typically only available in historically used earth tones (e.g., brown, reddish-brown, blonde), electric violas may be traditional colors or they may use bright colors, such as red, blue or green. Some electric violas are made of materials other than wood.

Most electric instruments with lower strings are violin-sized, as they use the amp and speaker to create a big sound, so they do not need a large soundbox. Indeed, some electric violas have little or no soundbox, and thus rely entirely on amplification. Fewer electric violas are available than electric violins. It can be hard for violists who prefer a physical size or familiar touch references of a viola-sized instrument, when they must use an electric viola that uses a smaller violin-sized body. Cale, formerly of The Velvet Underground, is one of the more notable users of such an electric viola and he has used them both for melodies in his solo work and for drones in his work with The Velvet Underground (e.g. "Venus in Furs"). Other notable players of the electric viola are Geoffrey Richardson of Caravan^[29] and Ramsey.^[30]

Instruments may be built with an internal preamplifier, or may put out an unbuffered transducer signal. While such signals may be fed directly to an amplifier or mixing board, they often benefit from an external preamp/equalizer on the end of a short cable, before being fed to the sound system. In rock and other loud styles, the electric viola player may use effects units such as reverb or overdrive.
