The banjo, with its loud and raucous tone, was replaced with the guitar, which provided a more subtle and secure pulsation (chunk-chunk) in the foundation rhythm. As the saying went, the guitar was more felt than heard. Listeners felt the combined sound of bass, guitar, and drums as a sonic force that pushed through cavernous dance halls. “If you were on the first floor, and the dance hall was upstairs,” Count Basie remembered, “that was what you would hear, that steady rump, rump, rump, rump in that medium tempo.”
