Art form making total return, in charge (5)
I believe the answer is:
music
'art form' is the definition.
(I know that music is a art form)
'total return in charge' is the wordplay.
'total' becomes 'sum' (synonyms).
'return' is a reversal indicator.
'in charge' becomes 'ic' (abbreviation for 'in charge').
'sum' written backwards gives 'mus'.
'mus'+'ic'='MUSIC'
'making' acts as a link.
(Other definitions for music that I've seen before include "Organised sound" , "Staff will support this" , "Audible art form ..." , "(Pleasant) sequence of sounds" , "Composer's product" .)
