Yellowcard, Nigel Kennedy, and Dave Matthews Band with Boyd Tinsley and Jean-Luc Ponty; U2 also frequently uses the violin, especially the electric violin. The violin is also a part of the huge phenomenon called cello rock. The hugely popular Motown recordings of the 1960s and 1970s relied heavily on strings as part of the trademark texture. Earlier genres of pop music, at least those separate from the Rock 'n' Roll movement, tended to make use of fairly traditional Orchestras, sometimes large ones; examples include the American "Crooners" such as Bing Crosby. Though bowed strings were heavily popular and relied upon in almost all types of music genre recordings in the 1960s and 1970s, disco music, which surged aggressively onto the music scene in the early to mid-1970s, also relied heavily upon strings within its compositions; in fact, almost all disco/dance music of that era incorporated the use of strings within its compositions and arrangements.

The 1980s saw an insurgence of electronic music mimicking strings with little or no use of traditional strings in music compositions. Now strings are making a comeback in pop music. Indian, Pakistani, Turkish and Arabic pop music is filled with the sound of violins, both soloists and ensembles. Jazz The earliest references to jazz performance using the violin as a solo instrument are documented during the first decades of the 20th century. The first great jazz violinist was Eddie South who is best known as the Dark Angel Of Violin.

Younger performers include Mat Maneri, Katt Hernandez and Regina Carter. Jazz fusion violinists include Jean-Luc Ponty and Michal Urbaniak. Folk music Like many other instruments of classical music, the violin descends from remote ancestors, cruder in form, that were used for folk music. Following a stage of intensive development in
