strange tones

[Dusk]

I'm arranging at the moment this song: https://www.youtube.com/watch?v=aOQbOwUPDy4
In the first 12 measures, I hear a melody (right hand) and a broken cord (left hand). But then some different tones appear. Anyone can hear them?

Thanks.

If your talking about those trilled chords they were in the song all the time.

And what are the tones, the cords consist of?

Just a little offtopic but still kinda ontopic: Wonderful use the of whole tone scale in that piece (I assume it's mostly in the whole tone scale or completely).

Bump.

And what are the tones, the cords consist of?

To me it sounds like said chords go: 3rd, 2nd, 3rd, 3rd, repeat. The top note of said chords is the same for the first three but going down a third on the fourth and eighth. I could be off, but that's what it sounds like to me.
