Hello David

I was looking for an easier way to play the Blues with the common three chords (C, F and G7 in the key of C). After playing around for some time I found a continuous scale for diatonic instruments. This means that the notes do always have the same steps. This allows to play 5 different major and 5 minor scales, which are related/similar to the circle of 4ths (and 5ths).

Now the nice thing about this is if you blow(push) or draw(pull) any three notes right next to then it will always result in a chord (triad in root position), major or minor depending where you are.
This makes it very easy if you want to use the instrument to accompany someone.

Its good for Blues and Jazz (Bluenotes)
