The contrast between these terrifying notes and the wailing of the flutes is especially curious.

We find nothing analogous to this anywhere else.
The delightful _Purgatoire_, where the author sees a chorus of souls in Purgatory, is much better.

His Purgatory has no punishments nor any griefs save the awaiting, the long and painful awaiting, of eternal happiness.

There is a processional in which the fugue and melody alternate in the most felicitous manner.

There are sighs and plaints, all haunting in their extreme expressiveness, a great variety beneath an appearance of monotony, and from time to time two wailing notes.
