This particular score was almost certainly used by an orchestra of the period. An instruction pencilled in at the bottom of the page tells the player when to "stand up" during the performance.
In this orchestral score, music is included for drums, piano, 1st and 3rd alto saxophones, 2nd tenor saxophone, violin, trombone, 1st and 2nd trumpet, tenor banjo, bass, and 1st violin. The price for the entire score was 50 cents.
