In music, a double stop is the act of playing two notes simultaneously on a melodic percussion instrument (like a marimba) or stringed instrument (for example, a violin or a guitar). In performing a double stop, two separate strings are depressed ("stopped") by the fingers, and bowed or plucked simultaneously (without a string change).

A triple stop is the same technique applied to three strings; a quadruple stop applies to four strings. Double, triple, and quadruple stopping are collectively known as multiple stopping.

The invention of the double-stop is generally credited to violinist Carlo Farina, whose Capriccio Stravagante (1627) was published in Dresden while he was Court-Violinist at Saxony.

Chuck Berry popularized the double stop riff as a cornerstone of rock guitar.

Pino Palladino (born 17 October 1957) is a Welsh bass guitarist who gained fame playing primarily rock and roll, blues rock, and rhythm and blues music, although he has been lauded for his ability to play most genres of popular music, including jazz, neo soul, and funk. His career has spanned several ensembles, including the John Mayer Trio and The RH Factor, a band mixing elements of soul, jazz and R&B, which he formed with jazz trumpeter Roy Hargrove. He was also Pete Townshend's and Roger Daltrey's first choice to fill the position left by John Entwistle as the bassist for The Who. Adding to an eclectic grasp and melodic approach on his instrument, he has become one of the most sought-after session players on the bass and has played on a large number of recordings by some of the world's most successful entertainers, in part, by mastering a variety of techniques on both his late 1970s fretless Music Man StingRay bass guitar and, later in his career, adding fretted Fender Precision and Jaguar basses. His playing has earned him custom instruments bearing his name.

James Marshall "Jimi" Hendrix (born Johnny Allen Hendrix; November 27, 1942 – September 18, 1970) was an American musician and singer-songwriter. He is widely considered to be the greatest electric guitarist in music history, and one of the most influential musicians of his era despite mainstream exposure limited to just three years. After initial success in Europe with his group The Jimi Hendrix Experience, he achieved fame in the United States following his 1967 performance at the Monterey Pop Festival. Later, he headlined the iconic 1969 Woodstock Festival and the 1970 Isle of Wight Festival. He often favored raw overdriven amplifiers with high gain and treble and helped develop the previously undesirable technique of guitar amplifier feedback.

Hendrix helped to popularize use of the wah-wah pedal in mainstream rock, which he often used to deliver tonal exaggerations in his solos, particularly with high bends, complex guitar playing, and use of legato. As a record producer, he also broke new ground in using the recording studio as an extension of his musical ideas. He was one of the first to experiment with stereophonic phasing effects for rock recording.^{[citation needed]} He was influenced by blues artists such as B.B. King, Muddy Waters, Howlin' Wolf, Albert King and Elmore James,rhythm and blues and soul guitarists Curtis Mayfield and Steve Cropper, and the jazz guitarist Wes Montgomery. Hendrix began dressing and wearing a moustache like Little Richard when he performed and recorded in his band from March 1, 1964 through to the spring of 1965. In 1966, he stated, "I want to do with my guitar what Little Richard does with his voice".
