Tiny thing taking time in musical work (5)
I believe the answer is:
motet
'musical work' is the definition.
(I've seen this in another clue)
'tiny thing taking time' is the wordplay.
'tiny thing' becomes 'mote' (I can't justify this - if you can you should believe this answer much more).
'taking' is a charade indicator (letters next to each other).
'time' becomes 't' (abbreviation).
'mote'+'t'='MOTET'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for motet that I've seen before include "Certain one is morally superior" , "Creating sacred piece" , "Short piece of church choral music" , "Polyphonic choral liturgical piece" , "musical piece" .)
