'music' is the definition.
(I know that ragtime is a type of dance music)

I can't explain the rest of the clue.

(Other definitions for ragtime that I've seen before include "Syncopated music genre" , "musical style" , "Early jazz style" , "Kind of jazz for Maigret" , "Kind of music" .)

I've seen this clue in The Sun.
