Can be sung when taking in air, possibly (5)

Ross

I believe the answer is:

arias

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

'can be sung' is the definition.
I can't judge whether this definition defines the answer.

'when taking in air possibly' is the wordplay.
'when' becomes 'as' (eg 'when I walked' means 'as I walked').
'taking in' means one lot of letters goes inside another.
'possibly' indicates anagramming the letters.
'air' anagrammed gives 'ria'.
'as' enclosing 'ria' is 'ARIAS'.
