I believe the answer is:

coordinates

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

'harmonises' is the definition.
I can't tell whether this definition defines the answer.

'different decorations' is the wordplay.
'different' is an anagram indicator (letters placed in a different order).
'decorations' is an anagram of 'COORDINATES'.

Can you help me to learn more?

I've seen this clue in The Times.
