Hi yahya and all

You can go to :

http://240edo.tripod.com/id7.html

to see details of my new models.

I am also working on a classification system based on system divisions
in consultation with dr.john chalmers wich these models will be
described with it.

but about your question , firstly these kind of systems and scales have
unequal divisions (with ascending or descending trends or as you can see
in link above lead to EDO in special conditions.

In the scale I proposed as :

1: 0.000

2: 90.000

3: 184.848

4: 284.545

5: 389.091

6: 498.485

7: 612.727

8: 731.818

9: 855.758

10: 984.545

11: 1118.182

12: 1256.667

13: 1400.000

I assumed first division , A1, as 90 cent and common difference as
4.848 cent so the next division , A2 , will be 94.848 cent.

In This non-octavic scale , you can see a tetrachord ( in 0 to 498.485
cent ) but the structure of scale is not tetrachordal.

The repetition of scale makes a heterogeneous intervallic structure that
all the degrees in the next repetition have 200 cent intervallic size
more than the main .(considering octave equivalency). If you start from
284.545 so you can have a pseudo-octave of 1205.455 and fifth of 700
cent.

So my music is based on different 12-tone scales and it is natural for
such systems.

Waiting for your kindly comments.
