You give the Romans way too much credit. They didn't even manage to export their style of music and had their tradition supplanted by the rest of Europe: Previously they were part of the Mediterranean tradition (which nowadays people recognise as oriental, definitely a misnomer), have a listen. Nowadays they have just as much as an allergy to flourishes as much of the rest of the continent (modulo Greece but also Spain, also at least parts of the Balkan)

...and this is just to serve as an example.
