Soft music (5)
I believe the answer is:
piano
This could be a double definition.
'soft' is the first definition.
(similar in meaning)
'music' is the second definition.
I know that 'music' relates to this answer. I also know that both the answer and definition are singular nouns
Can you help me to learn more?
(Other definitions for piano that I've seen before include "entertain with this softly" , "Musical instrument - softly, please" , "Softly (mus.)" , "Keyboard instrument" , "In musical notation, this means softly" .)
