Austrian composer of waltzes (7)
I believe the answer is:
strauss
'austrian composer of waltzes' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for strauss that I've seen before include "Composer of Salome and Elektra" , "scorer" , "US stars made the composer" , "Austrian composer of waltzes" , "34 [CRICKETER]" .)
