Distant cardinal, out of tune (3-3)
I believe the answer is:
off-key
'out of tune' is the definition.
(I've seen this before)
'distant cardinal' is the wordplay.
'distant' becomes 'off' (far off).
'cardinal' becomes 'key' (synonyms).
'off'+'key'='OFF-KEY'
(Other definitions for off-key that I've seen before include "Out of tune" , "Inaccurate in pitch" .)
