obligato

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

'address to musicians' is the definition.
I can't tell whether this defines the answer.

'a too glib order' is the wordplay.
'order' indicates an anagram.
'a'+'too'+'glib'='atooglib'
'atooglib' with letters rearranged gives 'OBLIGATO'.

Can you help me to learn more?

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