Dressage music (7)
I believe the answer is:
ragtime
This clue could be a double definition.
'dressage' is the first definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'music' is the second definition.
(ragtime is a kind of music)
Can you help me to learn more?
(Other definitions for ragtime that I've seen before include "Syncopated piano music from the 1890s" , "Syncopated piano music - migrate (anag)" , "Syncopated music form" , "Scott Joplin music style" , "Type of music" .)
