Soprano with plenty of taste (6)
I believe the answer is:
sample
'taste' is the definition.
(sample can mean to taste or try)
'soprano with plenty' is the wordplay.
'soprano' becomes 's' (musical abbreviation).
'with' means one lot of letters go next to another.
'plenty' becomes 'ample' (ample means enough or plenty).
's'+'ample'='SAMPLE'
'of' acts as a link.
(Other definitions for sample that I've seen before include "Small representative piece" , "instance" , "Take" , "Taste(r)" , "Small part representative of the whole" .)
