A clever solo for piano shows craft (5)
I believe the answer is:
sloop
'craft' is the definition.
(sloop is a kind of craft)
'a clever solo for piano' is the wordplay.
'a clever' indicates anagramming the letters.
'for' is a charade indicator (letters next to each other).
'piano' becomes 'p' (musical abbreviation).
'solo' anagrammed gives 'sloo'.
'sloo'+'p'='SLOOP'
'shows' is the link.
(Other definitions for sloop that I've seen before include "Sailboat" , "One-masted sailing ship" , "something that's rigged" , "Single-masted sailing boat" , "Sailing vessel with one mast" .)
