Musical entertainment somewhat discordant? (5)
I believe the answer is:
disco
'musical entertainment' is the definition.
(I've seen this before)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for disco that I've seen before include "Demonic spirit" , "Discotheque (abbrev.)" , "equipment for playing recordings" , "Music genre - dance venue" , "Club or party with dancing" .)
