End section of teeny violin periodically scratched (5)

I believe the answer is:

envoi

I'm a little stuck... Click here to teach me more about this clue!

'end' is the definition.
(I have seen 'End of poem' mean 'envoi' so perhaps 'end' could also mean 'envoi')

I can't explain the rest of the clue.

Can you help me to learn more?

(Other definitions for envoi that I've seen before include "Final stanza in ballad" , "End of poem" , "Conclusion of a poem or book" , "Short concluding stanza" , "Final message" .)

I've seen this clue in The Times.
