Twangy part for musician, as always (5)
I believe the answer is:
nasal
'twangy' is the definition.
(I've seen this before)
'part for musician as always' is the wordplay.
'part' says the answer is hidden in the clue.
'NASAL' can be found hidden inside 'for musician as always'.
(Other definitions for nasal that I've seen before include "Of sound, as if it came through the nose" , "pinched" , "To do with nose, say sound" , "Relating to a facial organ" , "Like some spray" .)
