Upright or grand
I believe the answer is:
piano
I believe this is a double definition.
'upright' is the first definition.
(I've seen this in another clue)
'grand' is the second definition.
(thesaurus)
(Other definitions for piano that I've seen before include "Musical instrument - play quietly" , "key holder" , "Clavier" , "Instrument with ivories" , "Upright type?" .)
