Japes disheartened graduate meeting church organist and composer (6)

I believe the answer is:

jsbach

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

'organist and composer' is the definition.
I know nothing about this answer so I can't judge whether this works.

'japes disheartened graduate meeting church' is the wordplay.
'disheartened' means to remove the middle letters (the middle or heart is removed).
'graduate' becomes 'BA' (someone with a Bachelor of Arts degree).
'meeting' says to put letters next to each other.
'church' becomes 'ch' (common abbreviation).
'japes' with its middle removed is 'js'.
'js'+'ba'+'ch'='JSBACH'

Can you help me to learn more?

I've seen this clue in The Irish Times.
