Lure tenor with type of music (4)
I believe the answer is:
trap
'lure' is the definition.
(thesaurus)
'tenor with type of music' is the wordplay.
'tenor' becomes 't'.
'with' means one lot of letters go next to another.
'type of music' becomes 'rap' (music genre).
't'+'rap'='TRAP'
(Other definitions for trap that I've seen before include "that may be sprung?" , "Rock; carriage; gin" , "Part of a snare" , "Trick" , "that may catch a speeding motorist" .)
