The finale of the opera is absolutely amazing. Don Giovanni
finally gets his come-uppance, when a stone statue of the
Commedatore comes to life and drags Don Giovanni off to Hell.
Actually, the statue first gives Don Giovanni a chance to
repent and mend his ways, but characteristically he refuses.
The drama of the music here is quite outstanding. The menace
of the statue and the accompanying threat of Hell is
brilliantly conveyed. Incidentally, there are definite
similarities between the style of this and the introduction to
the 38th symphony.
(This final scene is featured in the film
Amadeus, and was my first exposure to Don
Giovanni.)
