Composer with a namesake horn (5)

I believe the answer is:

sousa

(Other definitions for sousa that I've seen before include "Composer of "The Stars and Stripes Forever"" , "US march king" , "John Philip ---, US bandmaster" , "John Philip -, composer of famous marches (The Stars and Stripes for Ever)" , "US composer of marches" .)

I've seen this clue in The New York Times.
