panpipes

I'm a little stuck... Click here to teach me more about this clue!

'get a collection of reeds' is the definition.
I can't judge whether this defines the answer.

'quietly change nappies' is the wordplay.
'quietly' becomes 'p' (p for piano and quiet).
'change' indicates an anagram.
'nappies' is an anagram of 'anpipes'.
'p'+'anpipes'='PANPIPES'

'and' acts as a link.

Can you help me to learn more?

(Other definitions for panpipes that I've seen before include "Musical instrument made of reeds of different lengths" , "Crude wind instrument" , "Folk instrument" , "Simple wind instrument" , "Primitive wind instrument" .)

I've seen this clue in the Sydney Morning Herald.
