Note girl’s agreement to stay (7)

I believe the answer is:

tenancy

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

'agreement to stay' is the definition.
I can't judge whether this definition defines the answer.

'note girl's' is the wordplay.
'note' becomes 'te' (musical note).
'girl' becomes 'nancy' ().
'te'+'nancy'='TENANCY'

Can you help me to learn more?

(Other definitions for tenancy that I've seen before include "Let" , "Temporary occupation of land" , "Renting arrangement" , "Rental arrangement" , "Temporary occupation of property" .)

I've seen this clue in The Times.
