Too many flourishes form a tenor? (6)

I believe the answer is:

ornate

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

'too many flourishes form a tenor?' is the definition.
I can't tell whether this definition defines the answer.

'form a tenor?' is the wordplay.
'form' is an anagram indicator (another form of the letters).
'a'+'tenor'='atenor'
'atenor' is an anagram of 'ORNATE'.

Can you help me to learn more?

(Other definitions for ornate that I've seen before include "Florid" , "Highly decorative" , "Baroque" , "Fancy" , "Decorated with tan ore" .)

I've seen this clue in The Irish News.
