From emus I caught pleasant sounds (5)
I believe the answer is:
music
'pleasant sounds' is the definition.
(I've seen this before)
'from emus i caught' is the wordplay.
'from' says the answer is hidden in the clue.
'MUSIC' is hidden in the letters of 'emus i caught'.
(Other definitions for music that I've seen before include "Audible art form ..." , "Pleasing sound" , "Country, say" , "'If ... be the food of love, play on'(Twelfth Night)" , "being confined by bars?" .)
