Music with beat and vitality (5)
I believe the answer is:
tango
'music' is the definition.
(tango is a kind of music)
'beat and vitality' is the wordplay.
'beat' becomes 'tan' (I've seen this before).
'and' means one lot of letters go next to another.
'vitality' becomes 'go' (I've seen this in other clues).
'tan'+'go'='TANGO'
'with' acts as a link.
(Other definitions for tango that I've seen before include "Movement from Argentina" , "one followed by uniform" , "Modern ballroom dance" , "Activity requiring two to" , "Rhythmic movement" .)
