Some Liszt pieces (6)
I believe the answer is:
etudes
'some liszt pieces' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for etudes that I've seen before include "Musical compositions (French)" , "Set due in short musical compositions" , "Short pieces for solo instruments to show talent" , "Musical studies" , "Sue Ted over short musical compositions" .)
