Venetian baroque composer, died in Vienna 1741 (7)
I believe the answer is:
vivaldi
(Other definitions for vivaldi that I've seen before include "Venetian composer ("The Red Priest"), d. 1741" , "Italian composer, Antonio (d. 1741)" , "Baroque Venetian composer, d.1741" , "Italian composer of 'The Four Seasons'" , "Italian composer (the Red Priest) , d.1741" .)
