Move after beat in dance (5)
I believe the answer is:
tango
'dance' is the definition.
(tango is a kind of dance)
'move after beat' is the wordplay.
'move' becomes 'go' (synonyms).
'after' says to put letters next to each other.
'beat' becomes 'tan' (tan can mean to beat or hit).
'go' after 'tan' is 'TANGO'.
'in' is the link.
(Other definitions for tango that I've seen before include "Activity requiring two to" , "uniform to follow" , "Dramatic dance form Argentina" , "Dance originating in Argentina" , "Letter T in radio comms" .)
