Singular performances, whichever way seen (5)
I believe the answer is:
solos
'singular performances' is the definition.
The definition and answer can be both acts as well as being plural nouns.
Maybe they are linked in a way I don't understand?
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for solos that I've seen before include "Unaccompanied parts" , "Pieces of music for one voice or instrument" , "Musical passages for one instrument" , "Numbers" , "Passages for one player" .)
