Flatpicking (or simply picking) is the technique of striking the strings with a pick (also called a plectrum) held between the thumb and one or two fingers. It can be contrasted to fingerstyle guitar, which is playing with individual fingers, with or without wearing fingerpicks. While the use of a plectrum is common in many musical traditions, the exact term "flatpicking" is most commonly associated with Appalachian music of the American southeastern highlands, especially bluegrass music, where string bands often feature musicians playing a variety of styles, both fingerpicking and flatpicking. Musicians who use a flat pick in other genres such as rock and jazz are not commonly described as flatpickers or even plectrum guitarists. As the use of a pick in those traditions is commonplace, generally only guitarists who play without a pick are noted by the term "fingerpicking" or "fingerstyle".
Probably starting around 1930, flatpicking in American music was developed when guitarists began arranging old-time American fiddle tunes on the guitar, expanding the instrument's traditional role of rhythm guitar accompaniment with an occasional run on the bass strings. Although early guitarists such as Riley Puckett used a thumb pick to emphasize bass notes, this part of the style was adapted into flatpicking.
The melodic style in bluegrass is often fast and dynamic, with slides, hammer-ons, pull-offs, powerful strumming and rapid crosspicking. Bluegrass flatpickers usually prefer guitars with a flat top rather than an arch top, and steel strings rather than nylon.
The chief exponents of the early country and bluegrass flatpicking styles included George Shuffler, Alton Delmore, Johnny Bond, Don Reno and Bill Napier. The lead guitar was sparsely used, and sometimes was considered a novelty. Other instruments may also be used in flatpicking, such as the mandolin. However, banjo styles such as plectrum banjo and tunes played on tenor banjos can be played either by strumming or with a plectrum but they are not commonly known as flatpicking. This style can be typified by players such as Eddie Peabody, and has connections to ragtime and dixieland music.
The foundation of Puckett, Reno and others were built upon heavily in the 1960s by Doc Watson and Clarence White. Watson and White both legitimized the acoustic guitar as a lead instrument in bluegrass and old-time country music. White brought guitar flatpicking to the forefront of bluegrass, while Watson brought flatpicking to folk audiences as he played fiddle tunes, blues, country, and gospel songs throughout America.
Building on the contributions of Doc Watson and Clarence White, artists such as Norman Blake, Dan Crary, John Carlini, Mark O'Connor, Russ Barenberg, Larry Sparks, and Tony Rice further developed the art of flatpicking. Rice likely had the most profound impact on bluegrass guitar playing of anyone since his musical hero, Clarence White. Rice's tone, rhythm, phrasing, and improvisational skills have influenced an entire generation of bluegrass guitarists. Important elements Rice has used in his playing are jazz type chord substitutions, different from the straight major and minor chords common to bluegrass, and the use of the Dorian mode and the minor pentatonic "blues" scale in his lead playing. While there have been several songs using the Dorian mode in Appalachian roots music, Rice made a different statement by using this scale to improvise during songs written in a major key. For instance, he is very well known for playing an F major scale during a song written in G major (the F major scale, when played from G to G, is a G Dorian mode). The use of this technique introduces the flat 3rd (Bb) and the flat 7th (F) over the G chord which has a unique sound popular in bluegrass.
In recent years, players such as David Grier, Bryan Sutton, Beppe Gambetta and Tim Stafford have carried the guitar into the next millennium. Also, current "young guns" like Cody Kilby, John Chapman, Chris Eldridge, Andy Falco and Sean Watkins continue to explore this style of guitar playing. These players are still defining new standards and reaching wider audiences. Pioneers Rice, Blake, Barenberg, and Crary continue to produce music featuring flatpicking as well.
