22 ET slow grunge

Ok... I'm trying to put into practice some of the things I've been thinking and talking about. I'm not too happy with this piece though what I did with using my guitar as a controller I think holds promise for many-note tunings, and in this case 22 EDO.

Specifics:

I used my Fender Mustang and the Roland GR 20 as a controller to drive pianoteq, z3ta+ and albino - all of them in 22 edo. Pianoteq was run through native instruments guitar rig which gives the piano an almost grunge guitar sound. Session Drummer 3 provides the beats.

To get the piano into the proper register I made pianoteq transpose down 24 steps. This made it difficult to go back and add melodies because I couldn't transpose (live) the other two synths and as a result the mapping of the frets to notes changed.

So... this is a bit rough - perhaps should be more up tempo. But it is my most recent attempt to put my music where my mouth has been.

This piece is really interesting Chris;

My myopic view is that you are using a limited set of LucyTuned intervals.

In this case you are demonstrating both the consonant and the "less pleasant" intervals to generate novel and interesting sounds.

The question that immediately crosses my mind is:

"Why don't you just go for 88edo, and allow yourself even more variety?"

I have tended to use what I consider to be "consonant intervals" so I really appreciate hearing the "outer limits" that you are exploring.

This page gives my "myopic" view of how 22edo works harmonically.

Neat Chris, I think this has potential. The floaties sometimes
sounded out of tune to the rest, though I realize that may have
been intentional. Anyway... cool. -Carl

Christopher, this piece is grindy, gunky and groggy! Still I found it
rather pleasant to listen to. It's good to see such a garage-crunch
production from a microtonalist.

Hi Charles, thanks for the listen and comment.

I think 88 EDO would totally swamp my guitar - I doubt I could have a full
octave.

Since I'm playing by ear - and pattern - I am picking out the intervals and
sonorities that appeal to me - however, I'm moving the block chord pattern
with 22 edo steps. One of the scales I found in this piece went 3 - 2- 2 -
2- 1- 2 steps of 22 edo (if I remember correctly)

Quite honestly the PDF is hard to decipher. I saw a graphical representation
of 12, 17, 19, and 22 EDO (as I remember) that was easy for me to grasp.
I'll see if I can dig that up.

Hi Carl,

Thanks for the listen and comment. Since I transposed the piano part it made
it hard to relate the next layered parts to the chord pattern - so yes some
seem.... iffy I agree.

I didn't think too much of this piece to be honest so the positive comments
are totally unexpected. The intent was to:

1. further use my guitar as a controller via the Roland GR 20
2. test if indeed my other midi interface cable was better (it is. trust
Roland products!!)
3. and play with micro with a beat as per the continuing discussion on the
Xenharmonic Alliance.

I actually started out the night practicing Black Sabbath's cornucopia from
Volume IV on the Roland GR20 using a string orchestra patch. That actually
worked out rather well. (I should try Sabbath in Lucy tuning :-) ) I'm
probably going to take a stab at the 18 EDO piece with my guitar.

You know, Chris, this does bring to mind some of the experimental tunings of punk guitarists like Greg Ginn of Black Flag or Thurston Moore or Lee Ranaldo of Sonic Youth. They're all famous for using weird tunings and even prepared guitars, in part since they had to use cheap, out-of-tune instruments so much in their lean years.

Hi Chris;

To put 88 frets per octave could make things pretty crowded.
I have used mandolin fretwire for close frets in the past, although I have yet to have tried so many per octave.

If you print out the pdf, it should be easy to see how it works.

The image on the screen is sorta large, yet it will print smaller on A4 paper perfectly, and then should be easy to line up and decipher.

I am assuming that you have placed 22 equal frets per octave on a guitar.

In meantone terms, as I understand what you are saying, from A 3-2-2-2-1-2 steps should (from A) (fifth guitar string) give you:

frets on 22 edo guitar = Notes from A would be called
0 A
3 D5b (i.e. D followed by 5 flats)
5 C#
7 Ax (i.e. A double sharp
9 Ebbb (i.e. E triple flat)
10 Fbbbb (i.e. F followed by 4 flats)
12 Cxx# (i.e. C followed by 5 sharps)

So the fifth fret will play the third against the open string, although the other intervals will be more dissonant.

I just played your track to my teenage (critic) who is always tuned into what the musical kids are into.

His comment was "That's very Cool!". "It's not that grungy"

Charles - I haven't re-fretted my guitar - I am using a guitar synthesizer,
called the Roland GR-20
http://www.roland.com/products/en/GR-20/

that lets me convert my playing into MIDI - and from there I used the
traditional VSTi's that support retuning.

So then every fret on my 12-tet guitar translates into a step in 22 EDO.

though I'm trying to find a way to get a 22 EDO fretted neck for my strat
copy. Am I missing the link to the PDF or are you referring to the previous
one?

Please tell your son I think its great he thinks its cool.

I love the guitar chords! Do I hear them right as 7-limit tetrads?
This is another demonstration for the suitability of 22ET for bluesy/rock-related music. I really gotta find some time to to some 22ET blues stuff...

Hi Hans,

Thanks for the listen and comment. I'm still pretty ignorant of the finer
points of tuning and wouldn't know a 7-limit chord if it hit me. But perhaps
you (or someone else) can help in this respect.

The main chord pattern is based off of this construct (from bottom to top)

Bb, Eb, G, D in 12 TET so that translates to

5 steps, 4 steps, and 7 steps in 22 EDO as intervals or

as the "scale steps" 0, 5, 9, 16 stacked vertically in 22 EDO.

I was using terminology from Paul Erlich's paper on 22EDO (http://lumma.org/tuning/erlich/erlich-decatonic.pdf). A 7-limit major tetrad is, in just intonation, a 4-element chord with the interval ratios 7:6:5:4, sounding roughly like a dominant seventh chord (that's why it has a good use in bluesy music). In 22EDO, this is a chord with the pattern 7 steps, 6 steps and 5 steps, or stacked 0-7-13-18. The point is that in 22EDO, the minor-seventh-like interval formed by 18 steps is a quite good approximation for the interval ratio 7/4, making the chord distinctly more consonant than in 12EDO.

Hmm - aren't these numbers the numbers of steps in 12EDO? I think Bb-Eb-G-D in 22EDO steps is 9 steps, 7 steps and 13 steps, isn't it?

So it seems my guess was quite wrong. Strange, I was sure I heard a minor seventh in the first chord of your piece.
Gotta try out this chord myself...

Hi Hans,

The way I'm doing this is playing a 12 TET guitar that has a midi pickup.
The midi then goes to pianoteq which is running with a 22 EDO tuning. So...
then a semitone in 12 TET equals a 1/22 step in 22 EDO. So... if I have a
major 3rd in my 12 TET score it sounds as a 22 EDO interval of 4 1/22 steps.

Does that make any sense?

I would like to point out that I believe the chord to be an "inversion" if
you believe in such things.

Chris

Got it clear now. Yes, the pattern 0, 5, 9, 16 in 22EDO is indeed an "inversion" of a 7-limit major tetrad (with the fifth in the bass).
Glad my ear did not deceive me so much...
