A spirited harp player? (5)

I believe the answer is:

angel

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

'harp player?' is the definition.
(I've seen this in another clue)

'a spirited' is the wordplay.
'a' becomes 'an'.
'spirited' becomes 'gel' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'an'+'gel'='ANGEL'

Can you help me to learn more?

(Other definitions for angel that I've seen before include "lady (very kind)" , "somewhere in Islington" , "One backing theatre production" , "Glean (anag.)" , "Theatrical backer" .)

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