"Globosa"is based on what i call 7-tone augmented scale in 19TET.There
are some transpositions,and other notes in the end.

The generator is a major third,and the structure is LsLssLs,with L
being 5 steps and s being 1 step.The scale contains only 2 fifths and
isn't particularly suited for use as a basis of entire
melodies(although that is exactly what i've done here).

Rather the purpose of scales like this and the diminished scale i used
for"Skopnytt"is to provide an alternative tonality,in the same way the
augmented,diminished and whole-tone scales are used in some 12TET
music.

So here i will attempt a rundown of the different scales available in
19TET.

Diatonic(L=3 s=2)-Fifth is generator
LLsLLLs

Pentaenharmonic(L=3 s=1)-Half-fourth is generator
sLsLLsLsL

Diminished(L=4 s=1)-Minor third is generator
LsLsLsL

Augmented(L=5 s=1)-Major third is generator
LsLssLs

Also there is an 8-tone scale i haven't figured out yet what it should
be called,L=3 s=2 and using the supermajor third as a generator:
ssLssLsL
It contains only one fifth.

There are also a bunch of"borderline MOS"scales that has all but one
interval of the same size,such as the"whole tone scale",but these i do
not count.

Also all of the generators mentioned above have higher-number MOSes
that can be used as a source for Meta-MOSes,or more complex chromatic
composition.There are also smaller MOSes within each of them,but those
can easily be discovered when playing.(such as the pentatonic within
the diatonic)

Also there are the various altered and Meta-MOS modes of the scales in
here, that i may go through another time. I'd like to know if anyone
finds this useful, as i have similar info on other ETs.

Hi Mats.

Might I suggest raising this as a subject of discussion at

tuning-math@yahoogroups.com

Some people might think these should count the most.

This is very close to the stuff we're discussing at tuning-math.

Could you make a webpage?
