Tunes accompanied by graces? (4)
I believe the answer is:
airs
'tunes' is the definition.
(air can mean a piece of music)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for airs that I've seen before include "Pretentiousness" , "- - and graces" , "'Tunes, melodies (4)'" , "Ventilates or tunes" , "Voices" .)
