Although the cha-cha-chá rhythm originated with Orquesta América, some scholars, including John Santos (1982), consider the Orquesta Aragón of Rafael Lay and Richard Egües, and the orchestra Fajardo y sus Estrellas of José Fajardo, to have been particularly influential in the development of cha-cha-chá. The coincidental ascendance of television and LP records in the 1950s were significant factors in the sudden international popularity of the music and dance of cha-cha-chá.
