Item following piano piece (8)
I believe the answer is:
particle
'item following piano piece' is the definition.
'particle' can be an answer for 'piece' (I have seen 'Tiny piece ' mean 'particle' so perhaps 'piece' could also mean 'particle'). I'm unsure of the 'item following piano' bit.
'piano piece' is the wordplay.
'piano' becomes 'p'.
'piece' becomes 'article' (I've seen this before).
'p'+'article'='PARTICLE'
Can you help me to learn more?
(Other definitions for particle that I've seen before include "Small amount" , "Prelatic (anag.)" , "One word" , "Scrap" , "Grain, tiny piece" .)
