Highly strung art form? (6)
I believe the answer is:
mobile
This clue might be a double definition.
'highly strung art' is the first definition.
'mobile' can be an answer for 'art' (mobile is a kind of art). I am unsure of the 'highly strung' bit.
'form?' is the second definition.
(mobile is a kind of form)
Can you help me to learn more?
(Other definitions for mobile that I've seen before include "Able to move or be moved easily" , "having transport available" , "Moveable, phone say" , "hoi polloi, as was" , "Portable phone" .)
