Pushing this scale a bit farther

So, I'm still using the same scale and trying to wrestle more from it.

To recap -- it is made of two major triads a tritone apart. C and F# for example.

Today I wrote a canon at the fifth. One scale (the lower) is C and F#, the other is G and C#.

A simple canon that wears its tritone on its sleeve--starting in C major and ending in F#.
