Theorem, if true, rejigged signature aspect of a waltz (5-4,4)
I believe the answer is:
three-four time
'a waltz' is the definition.
Both the answer and definition are singular nouns.
Perhaps they are linked in a way I don't understand?
'theorem if true rejigged signature aspect' is the wordplay.
'theorem if true' can be anagrammed to 'THREE-FOUR TIME'.
However, I'm not sure how the anagram is indicated.
'of' is the link.
Can you help me to learn more?
(Another definition for three-four time that I've seen is " Waltz tempo".)
