Dance beat with energy (5)
I believe the answer is:
tango
'dance' is the definition.
(tango is a type of dance)
'beat with energy' is the wordplay.
'beat' becomes 'tan' (tan can mean to beat or hit).
'with' says to put letters next to each other.
'energy' becomes 'go' (go can mean energy or enthusiasm).
'tan'+'go'='TANGO'
(Other definitions for tango that I've seen before include "tee" , "musical piece" , "Movement from Argentina" , "One from Argentina" , "reputedly takes two" .)
