I arranged this more then 50 years ago, at about the age of 18. Somehow I kept it all these years, written in my handwriting. Of course there were no music notation programs so long ago. I’ve never performed it. It should sound effortless, but it’s actually very difficult to play.
I assigned a color scheme to Dorian.
I am continuing with my idea of associating colors for modes and scales that are associated with major and minor. My idea is to assign to the color dark blue all the minor type scales that start off with the same first five notes. But I needed to differentiate between Aeolian, also known as natural minor, and Dorian. The two modes are almost the same, but Dorian has the higher 6th degree.
That one morph changes the mood a bit to something more exotic and a bit brighter. So for Dorian I chose blue for the main color but always with gold to accentuate the difference.
Many years ago I had in my mind the very beautiful version by SIMON AND GARFUNKEL, which by the way has almost 30 million views and almost 10 thousand comments – plus numerous likes. This famous version is in E Dorian. Mine starts in Bb Dorian then morphs to D Dorian. I did exit Dorian for Aeolian, for just one chord, using b6 instead of regular 6. The only other thing of importance is my modulation from Bb Dorian to D Dorian using the Trinity of chords idea. But at the time I did this I had no idea what that movement was, or that other composers use it. I did not come up with a name for this modulation until about five decades later.
