A soft-fruit show (6)
I believe the answer is:
appear
'show' is the definition.
(I've seen this in another clue)
'a soft-fruit' is the wordplay.
'soft' becomes 'p' (musical abbreviation for piano, 'soft').
'fruit' becomes 'pear' (pear is a kind of fruit).
'a'+'p'+'pear'='APPEAR'
(Other definitions for appear that I've seen before include "hove in sight" , "Become visible like ghost" , "Seem - come into view" , "Surface" , "Come on the market" .)
