The ska stroke up or ska upstroke, skank or bang, is a guitarstrumming technique that is used mostly in the performance of ska, rocksteady, and reggae music.[5] It is derived from a form of rhythm and blues arrangement called the shuffle, a popular style in Jamaican blues parties of the 1940s, 1950s and 1960s.
