Popular tune's familiar name (3)
I believe the answer is:
art
'name' is the definition.
'popular tune's familiar' is the wordplay.
'ART' is hidden within the letters.
But, I'm unsure how this is indicated.
Can you help me to learn more?
(Other definitions for art that I've seen before include "-- Garfunkel, singer" , "Beautiful or significant products of human creativity" , "Creative works; knack" , "crafty conduct" , "Trickery" .)
