Cheerful bit of syncopation (6)
I believe the answer is:
upbeat
This might be a double definition.
'cheerful' is the first definition.
(I know that cheerful can be written as upbeat)
'bit of syncopation' is the second definition.
The answer and definition can be both related to communication as well as being singular nouns.
Perhaps there's a link between them I don't understand?
Can you help me to learn more?
(Other definitions for upbeat that I've seen before include "Relentlessly optimistic" , "Cheerful and sanguine - as in music?" , "Conductor's beginning" , "maestro communicates this to orchestra" , "Optimistic (colloq.)" .)
