Steinway product (5)
I believe the answer is:
piano
'steinway product' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for piano that I've seen before include "Franz Liszt's instrument" , "Musical instrument - softly, please" , "Stringed instrument - to be played quietly" , "quiet passage" , "Soft, softly (music)" .)
