Musician to do a bit better than Queen (5)
I believe the answer is:
piper
'musician' is the definition.
(someone playing the bagpipes)
'do a bit better than queen' is the wordplay.
'do a bit better than' becomes 'pip' (I am not sure about this - if you are sure you should believe this answer much more).
'queen' becomes 'ER' (abbreviation for Elizabeth Regina).
'pip'+'er'='PIPER'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for piper that I've seen before include "Military musician" , "'Liam O'Flynn or Seamus Ennis, say (5)'" , "If you pay him, call the tune" , "Instrumentalist, solo or military" , "He who pays him, calls the tune" .)
