 Henderson's band, for example, began playing at the Roseland Ballroom in the early twenties; his repertoire included not only "hot jazz" pieces, but also waltzes in deference to the desires of the Roseland's patrons.Henderson's consideration of his audience points to the importance of entertainment in the performance of the variety of jazz that was overtaking New York City (incidentally, however, Henderson was not considered to possess the same caliber of showmanship as other performers, such as Duke Ellington, and some attribute his lack of showmanship as the primary reason for the commercial struggles he suffered).Variety in a band's repertoire meant the incorporation of both pop and jazz standards into most performances, which also allowed for the organic fusion of the two genres by those who performed both.
