This one has a splendid opening, better than my openings anyway, which are reliably weak.
Double notes can sound nice with that sort of texture too. With a few weeks practice you can get just as fast with them as with single notes, and they offer a wealth of harmonic combinations.
.....By double notes, do you mean thirds with one hand, or both hands playing scales a third (or some other interval) apart ...
It's interesting that the whole tone scale is associated strongly with Debussy. I wonder if there is a way to play the scale without making it sound like Debussy.
