Jaco Modern Electric Bass question

Hi. I going to work my way through this again and am already stuck. I have a good working knowledge of chord theory and major scale modes. Page 4 shows Melodic Minor Scale Modes. C Melodic Minor is the minor maj.7 chord. (sort of an aside but, doesn't the associated scale change when descending?) Looking at the next mode, C Dorian b2, why does it say "Bb Melodic" next to it, and why does each mode have a "__ Melodic" next to it? I don't see how the C Dorian b2 is Bb Melodic as seems to be implied here, or the others for that matter. :-(

I suspect that it's the second mode of Bb Melodic Minor, which will have C as Final, and Db as Supertonic (2nd).

On a related note, the melodic minor scale does differ* ascending from descending. Ascending it has a major 6th and a leading tone (or ^7). Descending there is a subtonic (minor 7th or b7) and a minor 6th.

* but only in the minds of the classically trained. The 'Jazz' version is the same in both directions - major 6th and 7th.

Thanks. I'll look at it from that viewpoint and maybe stop thinking about it so much. I do tend to want to analyze. Carol Kaye reminds me not to :-)

On the related note, I started thinking maybe I was confusing melodic with harmonic minor. Can of worms for me.

Harmonic minor has a minor 6th and leading tone (major 7th), with an augmented 2nd between them. It's what makes the dominant chord major in the minor key ('V' not 'v'), and is the same ascending and descending.

The example I believe demonstrate the modes starting always on the same root and therefore give you the relative scale.

Just like we can do with the modes from the major scale by starting each scale from C instead of going up the scale.

Here is an example:
C Ionian is from C major scale
C Dorian is from Bb major scale
C Phrygian is from the Ab major scale and so on...

As a reminder, in jazz harmony the melodic minor scale stays the same when going down because scales and modes can be played over specific chords.
In classical music I don't believe that scale was been used for its modes rather then the first degree. May be someone can prove me wrong on that ;-)

Analysis is good! The ultimate goal is to do it so much that you don't even have to think about it while playing.

For the record, I can't do that :)
 
I think this is not specifically related to the Jaco video. It’s just some appendix that someone else wrote. It’s not even there in all the video booklets. I have an old copy of the original booklet I think. But there are a lot of mistakes in it. Not sure if they got corrected in later versions?

This. It's filler to pad the page count.

Jaco would advise you to learn the melody.
