Get lost in jazz style (4)
I believe the answer is:
scat
I believe this is a double definition.
'get lost' is the first definition.
(informal imperative meaning 'go away')
'jazz style' is the second definition.
(I've seen this before)
'in' acts as a link.
(Other definitions for scat that I've seen before include "Dropping" , "Jazz singing - animal droppings - silvery fish" , "leave quickly" , "Animal droppings - small silvery fish" , "improvisation in jazz" .)
