Stravinsky perhaps has one work beginning in “Rite” (4)
I believe the answer is:
igor
'stravinsky perhaps' is the definition.
(as in the composer Igor Stravinsky)
'one work beginning in rite' is the wordplay.
'one' becomes 'i' (Roman numeral).
'work' becomes 'go' (synonyms).
'beginning in' says to take the initial letters.
The initial letter of 'rite' is 'r'.
'i'+'go'+'r'='IGOR'
'has' acts as a link.
(Other definitions for igor that I've seen before include "Card game" , "Prince of Russian opera" , "Prince in Borodin's opera" , "Prince of grand opera" , "Hero of Borodin" .)
