“I taught them everything they know, but not everything I know,” he wrote in an autobiography.

The funk Mr. Brown introduced in his 1965 hit “Papa’s Got a Brand New Bag,” was both deeply rooted in Africa and thoroughly American. Songs like “I Got You (I Feel Good),” “Cold Sweat,” “Get Up (I Feel Like Being a) Sex Machine” and “Hot Pants” found the percussive side of every instrument and meshed sharply syncopated patterns into kinetic polyrhythms that made people dance.

Mr. Brown’s innovations reverberated through the soul and rhythm-and-blues of the 1970s and the hip-hop of the next three decades. The beat of a 1970 instrumental “Funky Drummer” may well be the most widely sampled rhythm in hip-hop.

Mr. Brown’s stage moves — the spins, the quick shuffles, the knee-drops, the splits — were imitated by performers who tried to match his stamina, from Mick Jagger to Michael Jackson, and were admired by the many more who could not. Mr. Brown was a political force, especially during the 1960s; his 1968 song “Say It Loud — I’m Black and I’m Proud” changed America’s racial vocabulary. He was never politically predictable; in 1972 he endorsed the re-election of Richard M. Nixon.

In 1988, intoxicated on PCP, he burst into an insurance seminar adjoining his own office in Augusta (and accused them of using his personal bathroom), then led police on a car chase across the South Carolina border. He was sentenced to prison for carrying a deadly weapon at a public gathering, attempting to flee a police officer and driving under the influence of drugs, and was released in 1991.
