Put surface material on quiet avenue (4)
I believe the answer is:
pave
'put surface material on' is the definition.
'quiet avenue' is the wordplay.
'quiet' becomes 'p' (music symbol for 'piano').
'avenue' becomes 'ave'.
'p'+'ave'='PAVE'
(Other definitions for pave that I've seen before include "Cover with flat stones" , "Cover with flags" , "Dress with stone etc" , "Surface with stone etc." , "Cover with flagstones" .)
