Set out and set about finding six performers (6)
I believe the answer is:
sestet
'set' is the definition.
(I know that sestet is a type of set)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for sestet that I've seen before include "Set of six performers" , "musical ensemble" , "Group of six" , "Tsetse (anag.)" , "Six together" .)
