Uncle Fred's key (4)
I believe the answer is:
clef
'key' is the definition.
(I have seen 'Musical key' mean 'clef' so perhaps 'key' could also mean 'clef')
'uncle fred's' is the wordplay.
'CLEF' is hidden in amongst the letters.
However, I am unsure how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for clef that I've seen before include "Musical key or stave" , "Symbol on a stave indicating pitch" , "Symbol in musical score showing pitch of the notes" , "Pitch symbol on musical stave" , "symbol used by 6 [VERDI]" .)
