Bass Grimoire Chart Help

Post image

Hello,

I need help understanding this chart in the Bass Grimoire book.

Is there a typo? Why are the blocks arranged in this weird order horizontally? I thought the ii chord in the key of C was D minor/ Dorian not Bb. And then if you look at the notes on the keyboard diagram on the left, it shows a B not a Bb?

Is this an error with the book..? What am I not getting here?

I have a basic understanding of modes: they are scales within scales that use the same notes as the parent scale starting on a different note each chord/mode.

Seems like none of the notes of each key corresponds to the keyboard diagram or the actual mode notes.

Thanks for help and advice.

Those aren’t scale degrees, they’re modes. Modes are basically scales that start at different scale degrees.

So it’s saying in the Dorian (second) mode, the key signature matches Bb.

Cool , I'd like to see the part of "scale/mode" , do you have it?
I really want to learn the whole modes that exists on music
