Will need to be composed, as someone could be sleeping on this swing (5,5)
I believe the answer is:
sheet music
This might be a double definition.
'will need' is the first definition.
The definition and answer can be both related to communication as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'composed as someone could be sleeping on this swing' is the second definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'to be' acts as a link.
Can you help me to learn more?
(Other definitions for sheet music that I've seen before include "Printed part for performer" , "score" , "printed notepaper?" , "Leaves with scores" .)
