Kenny Rogers, a prolific singer who played a major role in expanding the audience for country music in the 1970s and Eighties, died on Friday at his home in Sandy Springs, Georgia. He was 81.

His death was announced by his publicist, Keith Hagan. He did not specify the cause but said Rogers had been in hospice care. Rogers retired from performing for health reasons in 2018.

Singing in a husky voice that exuded sincerity and warmth, Rogers sold well over 100 million records in a career that spanned seven decades. He had 21 No. 1 country hits, including two — Lady, written and produced by Lionel Richie, and Islands in the Stream, composed by the Bee Gees and performed with Dolly Parton — that reached No. 1 on the pop chart as well.

By the time he stopped performing, Rogers had placed more than 50 singles in the country Top 40, of which 20 also appeared in the pop Top 40. Long before the ascendancy of Garth Brooks and Shania Twain in the 1990s, he was among the first country artists to sell out arenas.

Rogers’s popularity stemmed partly from his genial persona and rugged good looks, but also from his ability to inhabit his material, which, he often said, was of two main types: love songs like You Decorated My Life”and narrative ballads like The Gambler and Lucille.

“All the songs I record fall into one of two categories, as a rule,” he said in a 2012 interview with NPR. “One is ballads that say what every man would like to say and every woman would like to hear. The other is story songs that have social significance.

“Reuben James was about a black man who raised a white child,” he continued, referring to a 1969 song that was a Top 40 hit for his group Kenny Rogers and the First Edition. “Coward of the County was about a rape. Ruby, Don’t Take Your Love to Town was about a guy who came home from war.”

Ruby in particular revealed Rogers’s command as an interpreter of narrative ballads. Written by Mel Tillis, the song is about a veteran, left impotent and in a wheelchair after being wounded in war, who must endure the agony of watching his wife leave the house every night to meet other men.

“And if I could move, I’d get my gun and put her in the ground,” Rogers broods as the record ends.
