Composer joining three short women (7)

I believe the answer is:

vivaldi

I'm a little stuck... Click here to teach me more about this clue!

'composer' is the definition.
(composer Antonio Vivaldi)

I can't explain the rest of the clue.

(Other definitions for vivaldi that I've seen before include "Baroque Venetian composer, d.1741" , "Italian composer of 'The Four Seasons'" , "Italian composer, Antonio (d. 1741)" , "Italian composer (the Red Priest) , d.1741" , "Venetian composer ("The Red Priest"), d. 1741" .)
