Dance requiring two wind instruments (8)
I believe the answer is:
hornpipe
'dance' is the definition.
(hornpipe is a kind of dance)
'two wind instruments' is the wordplay.
'two wind instruments' means two substitutions for 'wind instrument'.
'wind instrument' becomes 'horn' (horn is a kind of wind instrument).
'wind instrument' becomes 'pipe' (pipe is a kind of wind instrument).
'horn'+'pipe'='HORNPIPE'
'requiring' is the link.
(Other definitions for hornpipe that I've seen before include "Lively jig" , "piece of music for an > old dance" , "Lively old sailors' dance" , "Lively solo dance associated with sailors" , "Obsolete instrument: naval dance" .)
