Great opera. Puccini's last (he died composing it -- the final duet was completed by Franco Alfano, a colleague). Though Turandot is supposed to be a teenager, the intense demands of "In Questa Reggia" and the final duet dictate that a strong dramatic soprano has to play it and those voices tend to be attached to rather "large" women. While it's only 25 minutes of singing (Birgit Nilsson the great Wagnerian soprano use to call it her "party role"), it's quite a formidable challenge for most singers.
Did you see it at the Met? The Zefferelli production is eye-popping.
