It's noted for being honest and quiet (7,5)
I believe the answer is:
upright piano
'it's noted for' is the definition.
I can't tell whether this definition defines the answer.
'honest and quiet' is the wordplay.
'honest' becomes 'upright' (I've seen this in another clue).
'and' is a charade indicator (letters next to each other).
'quiet' becomes 'piano' (I've seen this before).
'upright'+'piano'='UPRIGHT PIANO'
'being' is the link.
Can you help me to learn more?
(Other definitions for upright piano that I've seen before include "The old joanna" , "Keyboard instrument" , "Musical instrument smaller than a grand" .)
