The electric guitar, a composite chordophone, requires external amplification for audibility. It employs pickups to convert string vibrations into electrical signals, shaped through amplifiers and effects for diverse timbres. Invented in 1932, it gained prominence in jazz ensembles for soloing. Pioneers like Les Paul, Charlie Christian, and Sister Rosetta Tharpe expanded its reach. By the 1950s and 1960s, the electric guitar became central to popular music. It's vital across genres, from rock and pop to blues, country, and jazz, contributing to the evolution of rock, blues, and heavy metal. With varied designs and techniques, it's a rhythm and lead instrument that shapes musical landscapes.
