Rushes to get some instrument parts (5)
I believe the answer is:
reeds
'rushes' is the definition.
(I've seen this in another clue)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for reeds that I've seen before include "Music-makers" , "Thatching stalks" , "Woodwind instruments" , "Tall water grasses on lake shore" , "Tall stiff marsh grasses" .)
