Notes dances having time brought forward (7)
I believe the answer is:
minutes
'notes dances' is the definition.
'minutes' can be an answer for 'notes' (I've seen this before). I'm not sure about the 'dances' bit.
'time brought forward' is the wordplay.
'time' becomes 'minute' (unit of time).
'brought forward' becomes 's' (I am not sure about this - if you are sure you should believe this answer much more).
'minute'+'s'='MINUTES'
'having' acts as a link.
Can you help me to learn more?
(Other definitions for minutes that I've seen before include "Written account of a meeting" , "Record of a meeting's decisions" , "summary" , "Recorded notes of a meeting" , "Records" .)
