Bore EU chum adjusted mouthpiece (10)

I believe the answer is:

embouchure

'mouthpiece' is the definition.
(I know that mouthpiece can be written as embouchure)

'bore eu chum adjusted' is the wordplay.
'adjusted' indicates anagramming the letters.
'bore'+'eu'+'chum'='boreeuchum'
'boreeuchum' is an anagram of 'EMBOUCHURE'.

(Another definition for embouchure that I've seen is " mouth".)

I've seen this clue in The Daily Mail.
