Classical piece penned by composer on document (5)
I believe the answer is:
rondo
'classical' is the definition.
(I know that rondo is a type of classical)
'penned by composer on document' is the wordplay.
'penned by' indicates the answer is hidden within the clue.
'RONDO' can be found hidden inside 'composer on document'.
'piece' acts as a link.
I am not very happy about this link. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for rondo that I've seen before include "Donor (anag) - piece of music" , "noted work" , "Music form with repeating theme" , "Repetitive musical form" , "Music form with recurring theme" .)
