Electric guitar

An electric guitar is a guitar that uses pickups to convert the vibration of its steel-cored strings (sometimes nickel) into an electrical current, which is made louder with an instrument amplifier and a speaker. The signal that comes from the guitar is sometimes electronically altered with guitar effects such as reverb or distortion. While most electric guitars have six strings, seven-string instruments are used by some jazz guitarists and metal guitarists.

The electric guitar was first used by jazz guitarists, who used amplified hollow-bodied instruments to get a louder sound in Swing-era big bands. The earliest electric guitars were made by the Rickenbacker company in 1931. While one of the first solid-body guitars was invented by Les Paul. The electric guitar was a key instrument in the development of many musical styles , such as Blues, early rock and roll, the late blues rock and it is also used in a range of other genres.

History

Some of the earliest electric guitars adapted hollow bodied acoustic instruments and used tungsten pickups

An early solid body electric guitar was designed and built by musician and inventor Les Paul in the early 1940s, working after hours in the Epiphone Guitar factory. His log guitar (so called because it consisted of a simple 4x4 wood post with a neck attached to it and homemade pickups and hardware, with two detachable Swedish hollow body halves attached to the sides for appearance only) was patented and is often considered to be the first of its kind, although it shares nothing in design or hardware with the solid body "Les Paul" model sold by Gibson. In 1945, Richard D. Bourgerie made an electric guitar pickup and amplifier for professional guitar player George Barnes. Bourgerie worked through World War II at Howard Radio Company making electronic equipment for the American military. Mr. Barnes showed the result to Les Paul, who then arranged for Mr. Bourgerie to have one made for him.

Uses

Popular music and rock groups often use the electric guitar in two roles: as a rhythm guitar which provides the chord sequence or "progression" and sets out the "beat", and a lead guitar, which is used to perform melody lines, melodic instrumental fill passages, and guitar solos. In some rock or metal bands with two guitarists, the two performers may perform as a guitar tandem, and trade off the lead guitar and rhythm guitar roles. In bands with a single guitarist, the guitarist may switch between these two roles, playing chords to accompany the singer's lyrics, and then playing a guitar solo in the middle of the song.

Jazz guitar playing styles include rhythm guitar-style "comping" (accompanying) with jazz chord voicings (and in some cases, walking basslines) and "blowing" (improvising solos) over jazz chord progressions with jazz-style phrasing and ornaments.
