Hold note and pass girl a drink (4,6)
I believe the answer is:
pina colada
'a drink' is the definition.
(I've seen this before)
'hold note and pass girl' is the wordplay.
'hold note' becomes 'pina' (I can't explain this - if you can you should give a lot more credence to this answer).
'and' is a charade indicator (letters next to each other).
'pass' becomes 'col' (col is a term for a mountain pass).
'girl' becomes 'Ada' (girl's name).
'pina'+'col'+'ada'='PINA COLADA'
Can you help me to learn more?
(Other definitions for pina colada that I've seen before include "Cocktail of rum, pineapple juice and coconut" , "alcoholic one" , "Perhaps contents of cocktail glass" , "Drink made of pineapple juice, coconut cream and rum" , "rum-based potation" .)
