Philadelphia Gray's Quick Step

Philadelphia Gray’s Quick Step is arranged in the key of F major and includes solfege. This composition was written by American musician and prolific composer, Francis Johnson during the Antebellum period. This style of song is reminiscent of jug band and string band music, which has become the sounds of  modern folk and bluegrass.

Johnson was the first African American composer to have his works published as sheet music. He was also the first African American to give public concerts and the first to participate in racially integrated concerts in the United States.  Francis Johnson led the first American musical ensemble to present concerts abroad, and he introduced the promenade concert style to America.
