diddley bow

It may have been influenced to some degree by West African instruments. Other nicknames for this instrument include "jitterbug" or "one-string," while an ethnomusicologist would formally call it a "monochord zither."

The diddley bow derives from instruments used in the Sahel region of West Africa, in places such as northern Nigeria and Mali. There, they were often played by children, one beating the string with sticks and the other changing the pitch by moving a slide up and down. The instrument was then developed as a children's toy by slaves in the United States. They were first documented in the rural South by researchers in the 1930s. The diddley bow was traditionally considered an "entry-level" instrument, normally played by adolescent boys, who then graduate to a "normal" guitar if they show promise on the diddley bow. However currently, the diddley bow is also played by professional players as a solo as well as an accompaniment instrument. The diddley bow is significant to blues music in that many blues guitarists got their start playing it as children, as well as the fact that, like the slide guitar, it is played with a slide. However, because it was considered a children's instrument, few musicians continued to play the diddley bow once they reached adulthood. The diddley bow is therefore not well represented in recordings.

The diddley bow is typically homemade, consisting usually of a wooden board and a single wire string stretched between two screws, and played by plucking while varying the pitch with a metal or glass slide held in the other hand. A glass bottle is usually used as the bridge, which helps amplify the sound. Some diddley bows have an added resonator box under the bridge, and are essentially single-string cigar box guitars. Some recent diddley bows are electrified with pickups.

One notable performer of the instrument was the Mississippi blues musician Lonnie Pitchford, who used to demonstrate the instrument by stretching a wire between two nails hammered into the wood of a vertical beam making up part of the front porch of his home. Pitchford's headstone, placed on his grave in 2000 by the Mount Zion Memorial Fund, is actually designed with a playable diddley bow on the side as requested by Pitchford's family. • Illustration — An electric diddley bow Other notable traditional players include Jessie Mae Hemphill, Eddie "One String" Jones, Napoleon Strickland, James "Super Chikan" Johnson and One String Sam. Willie Joe Duncan was also notable for his work with a large electrified diddley bow he called a Unitar. Buddy Guy learned to play music on a two-string homemade diddley bow before getting his first guitar (a Harmony acoustic). As a child, blues musician Elmore James describes using a diddley bow: he "plucked a wire strung on the wall of his house while sliding a bottle along it to vary the pitch." Recent performers who use similar instruments include New York City-based jazz pianist Cooper-Moore, American bluesman Seasick Steve, Andy Slater a.k.a. Velcro Lewis, and Chicago-based percussionist Coco Elysses. Jack White makes one at the beginning of the movie It Might Get Loud, then after playing it quips, "Who says you need to buy a guitar?". Seasick Steve recorded a tribute to his diddley bow, via his song "Diddley Bo" from his 2009 album, Man From Another Time.
