Where some players sit and read their notes (5)
I believe the answer is:
desks
'where some players' is the definition.
Although both the answer and definition are plural nouns, I can't see how they can define each other.
'sit and read their notes' is the wordplay.
I cannot really understand how this works, but
'notes' could be 'de' (two musical notes) and 'de' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for desks that I've seen before include "Office tables" , "Office furniture" , "School furniture" , "Workstations" , "Office equipment" .)
