Your chart is the same as my references.
Here is the algorithm - All Chords are Stacked thirds from the scale
Dan: thanks for sharing your chart; it has a lot more info than mine and I'll add it to my reference binder and grow into it as the needs arise. I went down the list and our charts do agree except for some enharmonic differences. I notice your chart contains E# and B# I'm sure for good reasons I don't yet understand but that's ok. My main usage for this is to help build better bass arpeggios. A distant 2nd usage is to work out how to play minor chords on my Korg.
Mario: thanks to you too. You explain things well. A "meta-lesson" for me here is to always hitch my wagon to the established lexicon of music theory. I will never understand it all but it is incredibly well thought out and has probably been refined over the centuries to where it is today. Even though I'm "nearly blind" thanks for not telling me the sky is green
swingbabymix: I apologize if I hi-jacked your thread but you appeared to have disengaged at the start of this discussion and I saw an opportunity to plug a hole in my theory knowledge. Hopefully you learned something here, I know I did.
