As early as the 1910s there had been dance orchestras playing the popular songs of the day along with a smattering of jazz. But the first to truly perform and record orchestral jazz was Fletcher Henderson, starting in about 1923, who gathered from smaller quintets and sextets a number of notable New York based players and formed the first full jazz orchestra.)
