Major chords and tritone

This canon is composed on a scale that is built on two major chords a tritone apart:

E and Bb.

The tritone divides the octave exactly in half and therefore gives a great resource for symmetry.

I start by arpeggiating the chords -- one in each part, right at the beginning to kind of stake out the territory.

It's really quite straightforward.
