Composer notes the new kiln (9)
I believe the answer is:
beethoven
'composer' is the definition.
(Beethoven is an example)
'notes the new kiln' is the wordplay.
'notes' becomes 'be'.
'new' indicates an anagram.
'kiln' becomes 'oven' (I've seen this before).
'the' anagrammed gives 'eth'.
'be'+'eth'+'oven'='BEETHOVEN'
(Other definitions for beethoven that I've seen before include "Pastoral Symphony composer, d. 1827" , "German barman" , "Composer of Fidelio, d. 1827" , "See 1" , "Ludwig van .. . . . . . . ., great German composer" .)
