Instrument chosen with right pitch, occasionally by ear? (8,5)

I believe the answer is:

electric organ

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

'instrument' is the definition.
(I know that electric organ is a type of organ)

'chosen with right pitch occasionally by ear?' is the wordplay.
'chosen' becomes 'elect' ('elect' as an adjective can mean chosen).
'with' is a charade indicator (letters next to each other).
'right' becomes 'r' (common abbreviation).
'occasionally' means one should take alternating letters.
'by ear?' becomes 'organ' (ear is a kind of organ. I am not sure about the 'by' bit.).
The alternate letters of 'pitch' are 'ic'.
'elect'+'r'+'ic'+'organ'='ELECTRIC ORGAN'

Can you help me to learn more?

(Other definitions for electric organ that I've seen before include "Synthesiser" , "Keyboard instrument" .)
