Crossword Genius

Duet for piano melody (4)

Ross

I believe the answer is:

pair

'duet' is the definition.
(I know that duet can be written as pair)

'piano melody' is the wordplay.
'piano' becomes 'p' (musical abbreviation).
'melody' becomes 'air' (air can mean a tune or melody).
'p'+'air'='PAIR'

'for' acts as a link.

(Other definitions for pair that I've seen before include "E.g. two aces; mate" , "Put together - two of a kind" , "Duo" , "item" , "Husband and wife" .)

I've seen this clue in The Globe and Mail.
