lehar

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

'composer' is the definition.
(Austro-Hungarian composer Franz Lehar)

'in subtle harmonies' is the wordplay.
'in' indicates the answer is hidden within the clue.
'LEHAR' can be found hidden inside 'subtle harmonies'.

'discernible' acts as a link.
This may not be right. It may be part of another bit of the clue.

Can you help me to learn more?

(Other definitions for lehar that I've seen before include "Operettist" , "Operetta composer" , "Hungarian who composed" , "Musician" , "He scored" .)

I've seen this clue in The Times.
