Glossary of Musical Terms

Variation

Variation form involves the repetition of a theme in changed versions. It is possible to vary the melody, its rhythm and its harmony, or to vary by addition. Early variation forms include the chaconne and the passacaglia, originally dances based on variations on a simple repeated bass or chordal pattern. Later examples of variations include Elgar's well known Enigma Variations and the Handel, Haydn and Paganini Variations of Brahms.

Verismo

Verismo (Italian: realism) is used in connection with the attempts at realism in late 19th century Italian opera, particularly with Mascagni's opera Cavalleria rusticana, followed by Leoncavallo's Pagliacci.

Vespers

Vespers is the evening service of the Divine Office, elements of which have proved suitable for more elaborate setting than the normal plainchant. Particularly notable in this respect is the 1610 compilation by Monteverdi for his published Vespers in Honour of the Blessed Virgin.

Vibraphone

A vibraphone is a form of metallophone with resonators below its horizontally arranged metal bars and a mechanism to allow a vibrato effect, giving the instrument a characteristic resonance. It has been used for special effects by a number of 20th century composers.

Vibrato

Vibrato is a technique of vibration used on various instruments and by singers, at one time used sparingly or not at all, but tending to over-use from performers anxious to conceal poor intonation.

Viol

Viols are bowed string instruments usually held downwards and therefore described as viole da gamba, (leg-viols), as opposed to instruments like the violin and its predecessors, held horizontally and described as viole da braccio, (arm-viols). Viols are made in various sizes, generally with six strings and with frets, lengths of gut tied round the neck and fingerboard of the instrument to show the position of the notes.

Viola

The viola (= German: Bratsche; French: alto) is the tenor of the modern violin family, with a range that extends a fifth below that of the violin and starts an octave above that of the cello. Violas are built in various sizes and were at one time used for both the alto and tenor registers.

Viola d'amore

The viola d'amore, used principally in the 17th and 18th centuries, is a bowed instrument generally with seven bowed strings and seven sympathetic strings, tuned to vibrate in sympathy with the playing strings. The instrument has a peculiar resonance of its own and has a small but interesting modern repertoire.

Violin

The violin, a bowed instrument with four strings, is used to provide the soprano and alto parts in the string section of the modern orchestra and the string quartet. It was developed in something approaching its modern form in the 16th century, gradually coming to occupy an unrivalled position because of its remarkable acoustical properties and its versatility.

Violone

The violone is the double bass of the viol family, although the word was once occasionally used with less accuracy to indicate the cello or any large viol.

Virginal

The virginal is a small harpsichord of varied shape and size. The word was used very generally in England in the 16th and 17th centuries for instruments of this type, with a keyboard and a mechanism by which quills plucked the horizontally stretched strings. The etymology of the word is uncertain, although it allowed obvious scope for Elizabethan and Jacobean punsters.

Vivace

Vivace, lively, is commonly used as an indication of tempo.

Vocalise

A vocalise is a vocal work, whether an exercise or not, that has no words. There is a well known and frequently transcribed Vocalise by Rachmaninov, and vocalisation is also called for in an orchestral context with the chorus parts of Neptune in Holst's suite The Planets.

Voice

Voice is used technically in music to indicate a particular musical line, even if this is intended for an instrumentalist and not a singer. The American 'voice-leading' is the equivalent of the English 'part-writing', writing different parts or lines of music for simultaneous performance.
