I've only seen a handful of contemporary classical pieces which feature the role of drum set. Even though the drum set is no older than the Western classical marimba (based on the African counterpart), it doesn't seem to enjoy the same level of usage within Western classical music. Why do you think this is? (I'm guessing it's because melodic compositions are easier to adapt to the melodic percussion.) Do you think there should be more drum set in classical music? Any recommendations for existing classical pieces with notably good drum set arrangements?
