In 1909 Handy and his band moved to Memphis, Tennessee, where they started playing at clubs on Beale Street. The 1912 publication of his Memphis Blues sheet music introduced his style of 12-bar blues; it was credited as the inspiration for the foxtrot dance step by Vernon and Irene Castle, a New York–based dance team. Some consider it to be the first blues song. Handy sold the rights to the song for US$100. By 1914, when Handy was 40, he had established his musical style, his popularity increased significantly, and he composed prolifically. Handy would move to New York City, but he always stressed the importance of Memphis to his style of music which became known as Memphis Blues.
