A melodic manner? (3)

I believe the answer is:

air

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

'manner?' is the definition.
(air can mean someone's manner or character)

'a melodic' is the wordplay.
'melodic' becomes 'ir' (I can't justify this - if you can you should believe this answer much more).
'a'+'ir'='AIR'

Can you help me to learn more?

(Other definitions for air that I've seen before include "Broadcast; tune" , "Atmosphere (of a melody?)" , "Musical composition" , "Region above the ground" , "voice giving > impression" .)

I've seen this clue in the Evening Standard.
