Rock violin is rock music that includes violin in its instrumental lineup. This includes rock music only and does not include classical style music using melodic motifs from rock. Rock music and rock and roll bands typically use electric guitar for the high range, and thus deploy violin only exceptionally. Nevertheless, some rock musicians have experimented with violin in a rock setting as either part of the backup (such as Paul McCartney's "Eleanor Rigby") or as a dual lead instrument sharing the spotlight, or alternating, with lead guitar. Violin as the featured lead instrument in the rock genre is a rarity and is more frequently associated with regional bands. Early history The emergence of rock music in the 1950s and 1960s is rooted in the basic instrumentation of drum kit, electric bass guitar and lead electric guitar; all of this instrumentation was fed into tube amplifiers until the emergence of the transistor. Building on this basic setup, other instruments were added as transistor technology advanced, typically the electric keyboard, which became popular after the introduction of the Moog synthesizer. Rock violin emerged in the art rock movement, which had experimented with classical instruments and musical influences associated with early music. Examples include Jethro Tull, King Crimson and Velvet Underground. In the same era that Ian Anderson popularized the use of flute in rock, others added violin to their line up. These bands included Jefferson Airplane, Fairport Convention, Mahavishnu Orchestra and John Mayall's Bluesbreakers. Technical basis Rock violin is played on solid body electric violins or on violins fitted with electric pickups. These are mounted on the bridge, on the sound post or stuck onto the body much as is done with acoustic guitar. Sizzling effects are achievable using aggressive bowing technique and runs high up the neck up to the limits of human hearing range. Due to the typical accompaniment of electric guitar, bass and rock drums, playing into the microphone may lead to impossibly high levels of feedback. Later history and development Rock fiddle, like rock music in general, owes much to blues. Incorporation of violin into rock, as with jazz, has been a slow process, resisted by some critics as an "unlikeliest and perverse misuse of an instrument". Categorization is more appropriately conducted using the flexible methodology of fuzzy logic insofar as the categories tend to overlap and ambiguity. However, rock has roots in folk music particularly the
