Global song in parts (5)
I believe the answer is:
round
I believe this is a double definition.
'global' is the first definition.
(similar in meaning)
'song in parts' is the second definition.
(a song with several vocal parts)
(Other definitions for round that I've seen before include "Spherical; song" , "Division of a boxing match - having a curved shape - drinks bought by one person" , "regular shape" , "(Of voice) rich, mellow" , "Like the World" .)
