Article turning mute on points identifying song (5,4)
I believe the answer is:
theme tune
'song' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.
'article turning mute on points' is the wordplay.
'article' becomes 'the' (the definite article in English).
'turning' is an anagram indicator.
'on' is an insertion indicator (as in clothing 'on' a person).
'points' becomes 'ne' (North and East).
'mute' anagrammed gives 'metu'.
'the' put within 'metu' is 'themetu'.
'themetu'+'ne'='THEME TUNE'
'identifying' is the link.
Can you help me to learn more?
(Other definitions for theme tune that I've seen before include "Identifying melody" , "Characteristic melody" .)
