The Tulsa Sound is a musical genre that developed in the 1960s in the city of Tulsa, Oklahoma. It combines elements from rock 'n' roll, blues, country, and gospel, creating a unique and laid-back sound. Artists like J.J. Cale, Leon Russell, and The Gap Band are associated with this style, which is known for its simple and rhythmic character, as well as the use of electric guitar and a simple, steady beat.
