Duets orchestrated always in common time (7)
I believe the answer is:
tuesday
'common time' is the definition.
The answer and definition can be both related to time as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'duets orchestrated always' is the wordplay.
'orchestrated' indicates an anagram (arranged, as music).
'always' becomes 'ay' (archaic term for 'always').
'duets' anagrammed gives 'tuesd'.
'tuesd'+'ay'='TUESDAY'
'in' is the link.
Can you help me to learn more?
(Other definitions for tuesday that I've seen before include "When Grundy was christened" , "forty eight hours before Chesterton's man" , "early in the week" , "24-hour period" , "24 hour" .)
