Duckwalk

[1] It is most widely known as a stage element of guitar showmanship popularized by rock 'n' roll guitarist Chuck Berry.

Chuck Berry's other guitar playing stunt, his one-legged hop routine with the other leg waving in the air is also known as a duckwalk.

[4] According to Levon Helm, drummer and singer for The Band, traveling medicine shows and music shows such as F. S. Wolcott's Original Rabbit's Foot Minstrels, established in 1911 and featuring African-American blues singers and dancers, would put on titillating performances in rural areas: "After the finale, they'd have the midnight ramble," Helm told Martin Scorsese in The Last Waltz.

[7] AC/DC guitarist Angus Young, whose musical style was heavily influenced by Chuck Berry, also does a duckwalk, in the form of a one-legged hop, in his shows.

[9] The duckwalk is one out of 25 exercises in the physical test at United States Military Entrance Processing Command (MEPS).
