Acoustic violins may be used with an add-on
piezoelectric bridge or body pickup, or a magnetic pickup attached to the fingerboard end. Alternatively, an electrodynamic pickup can be installed under an acoustic violin's fingerboard avoiding interference with any tone-producing parts of the violin, and therefore keeping its acoustic resonances and tone intact. To avoid feedback from the resonances of the hollow body under high amplification on stage, many instruments have a solid body instead. The
timbre (tone color) of a standard unamplified violin is due in large part to these resonances, but so depending on how the signal is picked up, an electric violin may have a "rawer" or "sharper" sound than an acoustic. This raw sound is often preferred in rock, pop and some
avant-garde genres. Several "semi-hollow" designs exist, containing a sealed, but hollow resonating chamber that provides some approximation of acoustic violin sound while reducing susceptibility to feedback. Solid-body electric violins typically have a non-traditional,
minimalistic design to keep weight down. Lately, materials such as kevlar, glass and carbon fibres, are used in the build process. They are often seen as "experimental" instruments, being less established than
electric guitar or
bass. Hence, there are many variations on the standard design, such as
frets, extra strings,
machine heads, "
baritone" strings that sound an octave lower than normal, and
sympathetic strings. Luthier
Yuri Landman built a 12 string electric violin for the Belgian band
DAAU. The strings on this instrument are clustered in four groups of three strings tuned
unison creating a
chorus. Also the instrument features an extra pickup in the tail piece for extra amplification of
string resonances. Acoustic 5-string violins are becoming more common, and it is not unusual for an electric violin to have 5, 6, 7 or more strings. The typical solid body also accommodates the extra tension caused by more strings without stressing the instrument too much. The extra strings are usually a low C string for 5-strings, a low C and low F for 6, and a low C, F and B for 7. Electric violin signals usually pass through electronic
processing, in the same way as an electric guitar, to achieve a desired sound. This could include delay, reverb, chorus, distortion, or other
effects. Today electric violins are even being used to reinvigorate music education. NBC, for example, recently featured a "music camp that combines rock and orchestra" by Mark Wood, who was chosen as the "person of the day" and featured on
Today for bringing fresh interest to music education with rock performances all on electric violins where proceeds are donated back to school music programs.
Today stated "The perfect blend of classical instruments and rock and roll is giving kids across the country a whole new appreciation for music." ==Pickups==
