Break charm with tune conducted from home (8)

I believe the answer is:

armchair

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

'conducted from home' is the definition.
I can't judge whether this defines the answer.

'break charm with tune' is the wordplay.
'break' indicates an anagram.
'with' means one lot of letters go next to another.
'tune' becomes 'air' (air can mean a piece of music).
'charm' is an anagram of 'armch'.
'armch'+'air'='ARMCHAIR'

Can you help me to learn more?

(Other definitions for armchair that I've seen before include "Roomy seat" , "Amateur" , "Seat with side supports" , "Seat to relax in" , "Piece of furniture" .)

I've seen this clue in the Sydney Morning Herald.
