I believe the answer is:

minim

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

'a note' is the definition.
(type of musical note)

I can't explain the remainder of the clue.

(Other definitions for minim that I've seen before include "Short note" , "Two crotchets in one" , "A note in music, half as long as a semi-breve- it's a palindrome" , "Feature of a score" , "Beat" .)

I've seen this clue in the Evening Standard.
