Debussy- Les tierces alternées

[thorn]

In a few weeks I am doing a concert of the Debussy Préludes, and I find this one pretty difficult to talk about in terms of keeping audience interest; like they've heard all but one of the others all of which have had something to grab their imagination and then you have this.

The only thing I can think of to say is along the lines of it anticipating the Etudes, but that won't mean much to a non musical audience, who may or may not even understand what a third is.

Help anyone?

There's a great color contrast if you have the faster sections very separated and without pedal and the slower sections more blurred, but what I think really sells it is just raw virtuosity.
