Rock music from Basie? (5)
I believe the answer is:
swing
This clue might be a double definition.
'rock' is the first definition.
(thesaurus)
'music from basie?' is the second definition.
'swing' can be an answer for 'music' (swing music is a kind of music). I am not certain of the 'from basie?' bit.
Can you help me to learn more?
(Other definitions for swing that I've seen before include "Jazz-like dance music" , "Music; hanging seat" , "in the park?" , "Big band jazz" , "Piece of playground equipment" .)
