Noted art form piercing low area - add sparkle down there? (8)
I believe the answer is:
vajazzle
'add sparkle down there?' is the definition.
I know nothing about this answer so I can't judge whether this works.
'noted art form piercing low area' is the wordplay.
'noted art form' becomes 'jazz' (I can't justify this - if you can you should give a lot more credence to this answer).
'piercing' means one lot of letters goes inside another (some letters pierce a hole in others).
'low area' becomes 'vale' (I've seen this in another clue).
'jazz' inserted into 'vale' is 'VAJAZZLE'.
Can you help me to learn more?
(Another definition for vajazzle that I've seen is " sparkling array 21A 20 [DOWN THERE]".)
