Sounds from Comus iconic (5)
I believe the answer is:
music
'sounds' is the definition.
(I have seen 'Melodious sounds' mean 'music' so perhaps 'sounds' could also mean 'music')
'from comus iconic' is the wordplay.
'from' indicates the answer is hidden within the clue.
'MUSIC' can be found hidden inside 'comus iconic'.
(Other definitions for music that I've seen before include "Country, say" , "Art form involving sound" , "being confined by bars?" , "Composed sound" , "melodies" .)
