One night in 1984, Compay Segundo, the Cuban singer and guitarist, heard in his dreams what would become his signature song.

“I woke up hearing those four sensitive notes,” Segundo recalled later on. “I gave them a lyric inspired by a children’s tale from my childhood, ‘Juanica y Chan Chan.’”

A hypnotic account of peasant life in Cuba, “Chan Chan” has a peculiar power, with four circular, mesmerizing opening chords that make it instantly recognizable. It gained a regional following when it was cut by the guitarist and singer Eliades Ochoa. But a recording of the song, in 1996, by a group of celebrated Cuban musicians who had been assembled for an album to be called “Buena Vista Social Club,” would become a phenomenon.

Now more than 25 years after its release, the best-selling world music album of all time has made it to Broadway in a new musical also titled “Buena Vista Social Club.” “Chan Chan” is among eight of the album’s 10 songs featured in the show and, perhaps not surprising for such a dramatic and mysterious track, it plays a crucial role in a pivotal moment in the story.

As the album of mostly older Cuban standards became a global sensation upon its release in 1997, Segundo’s song — about sifting sand by the sea and clearing a straw path along a journey to Cuban towns — became a standout all its own. “Chan Chan” was never released as a single, but the opening track has been streamed more than 250 million times on Spotify, almost three times more than anything else on the album. (That number is roughly the same as Toni Braxton’s “Un-Break My Heart” and Hanson’s “MMMBop,” both No. 1 hits in 1997.)
