16-tone Super-Aeolian pentatonic guitar scale chart
« on: February 21, 2012, 11:33:54 AM »



Superaeolian pentatonic:
This is an awesome higher harmony pentatonic scale that has 4:7:9:11:13 in it's inversions. 2*4/3 = maj7 and its really xenharmonic and weird as typically they'd lead to a min7.

For these diagrams, what are the intervals between the open notes?

@Ron: I suppose that should be 525 Cents (7 steps), not 450 (6 steps), am I correct?

For these diagrams, what are the intervals between the open notes?
If I didn't make a mistake, this should be 7 7 7 4 7 - so it's basically E A D G B E, except the 4ths are 525 Cents, and the step between "G" and "B" is 300 Cents.

An easy method to determine these intervals is to search for the unique 2 step interval, and count the number of steps it moves from string to string. On the A-string, it's between 14 and 16, on the D-string it's 7 steps to the left (between 7 and 9), and so on. ;)

hey youre right! that 450 should be 525.

although when i made the scale I wanted it to be 450...weird haha... ill fix it.....
basically, I just made a mistake and used 525 nstead of 450. but the 525 ended up being a pentatonic from mavila [9]

Thanks, I wondered how you built the scale, since I couldn't find a single generator for it. So you basically took mavila [9] (0 1 3 5 7 8 10 12 14 16), and removed every other note (0 3 7 10 14 16).

And I'm glad you wrote 450 Cents, because that made me wonder what would happen if you used a generator of that size (a subfourth or supermajor third). Seems the result is just 8-EDO, but I find it interesting how 3 successive notes in that chain of subfourths can be seen as a minor chord with a superfifth, or a major chord with a "subprime" (the root is lowered by 50 Cents), depending on the root.

i thought ireplied to this -
450 cent generator = sensi temperament .. basically bohlen pierce with octaves. 2.3.5.7 subgroup... no 2 and youre in BP land.

Yeah, this is a dead link to an image on Ron's old page that doesn't exist anymore.

Judging from the previous posts, the scale should look like following:

0 3 7 10 14 16 (in 16-EDO steps)
0 225 525 750 1050 1200 (in cents)

...and the scale diagram would be:

E|--1---5---7--10--14-----
B|--1---5---8--12--14-----
G|--0---2---5---9--12--16-
D|--0---3---7---9--12--16-
A|--0---3---7--10--14--16-
E|--1---5---7--10--14-----

As mentioned before in this thread, the string tuning is +7 +7 +7 +4 +7 from bottom to top in the diagram, so the "fourths" are 525 cents, and the "major third" between G and B is 300 cents.

Glad to see you here again, twistedblues! :)
