Musical king revamped scales beyond blemish (9)
I believe the answer is:
wenceslas
'musical king' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'revamped scales beyond blemish' is the wordplay.
'revamped' is an anagram indicator.
'beyond' is a charade indicator (letters next to each other).
'blemish' becomes 'wen' (wen is a kind of blemish).
'scales' is an anagram of 'ceslas'.
'ceslas' put after 'wen' is 'WENCESLAS'.
Can you help me to learn more?
(Other definitions for wenceslas that I've seen before include "Bohemian" , "Carol's good king" , "King in a Christmas carol" .)
