A top performer holding one can make music (5)
I believe the answer is:
sitar
'can make music' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
I also know that 'music' relates to this answer.
'a top performer holding one' is the wordplay.
'a top performer' becomes 'star' (I've seen this before).
'holding' is an insertion indicator.
'one' becomes 'i' (Roman numeral).
'star' enclosing 'i' is 'SITAR'.
Can you help me to learn more?
(Other definitions for sitar that I've seen before include "music-maker" , "Plucked instrument" , "Lasting from morning to night" , "Indian stringed instrument" , "Astir with Indian long-necked lute" .)
