Bill — depressed, we hear — making a scene (7)
I believe the answer is:
tableau
'a scene' is the definition.
(I know that tableau is a type of scene)
'bill depressed we hear' is the wordplay.
'bill' becomes 'tab' (a tab is a bill at a bar).
'depressed' becomes 'low' (synonyms).
'we hear' shows a homophone (sound like).
'low' is a homophone of 'leau'.
'tab'+'leau'='TABLEAU'
'making' acts as a link.
(Other definitions for tableau that I've seen before include "A scene with silent motionless group of people" , "pictorial presentation" , "Depiction of a scene by people in costume" , "Figures making a scene" , "'Frozen' theatrical scene" .)
