Minimalist composer has change of heart with ordinary musical effect (9)
I believe the answer is:
glissando
'musical effect' is the definition.
(I've seen this before)
'minimalist composer has change of heart with ordinary' is the wordplay.
I cannot quite understand how this works, but
'of' could be 'o' and 'o' is found in the answer.
'with' could be 'and' and 'and' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for glissando that I've seen before include "Re-interpreting this musical direction" , "Slide between two notes" , "Sliding effect in moving from one musical note to another" , "Sliding series of notes (mus.)" , "Musical flourish" .)
