Drop a note (5)

I believe the answer is:

minim

This clue is a double definition.

'drop' is the first definition.
(thesaurus)

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

(Other definitions for minim that I've seen before include "Two crotchets in one" , "Quarter of a breve" , "Palindromic note" , "Double crotchet" , "Note with value of half a semibreve" .)

I've seen this clue in the Evening Standard and The Globe and Mail.
