Monz,

You have probably already corrected the error at the end of the Interval Journal entry, which should read "to find the right article".

Keep up the good work.

Hi Mark,

Are you referring to this page?:

Exactly what error do you mean?

Also, i should have been more clear about
what i meant: while i appreciate being notified
of content errors, that's not what i'm
talking about this time.

As i said, we are making internal changes
to the website, and are at this time unable
to fix any errors of content. What i would
like to know about specifically are broken links,
missing graphics, and in general anything that
obviously should be present and/or working and is not.

When we are finished with the changes, around
the end of the year, then we can once again
repair errors of content.

Monz,

The error I was referring to was below the heading that read "Interval Journal", where you were talking about letting people access the old Interval Journals.

Below those words "Interval Journal", in the final sentence, there was a single word which needed to be deleted where you wrote "to find the right article." (I've forgotten what that single word was, but it was obvious that it needed to be deleted)

Only later did I realize that for now you are only interested in broken links and missing graphics.

Subject: A Piano Study in 17 ET

vaisvil

This is taken from today's blog post at


http://chrisvaisvil.com/?p=15

I'd prefer you'd leave comments at the blog.
(still trying to integrate all of the postings I make...)

A Piano Study in 17 ET

The genesis of this piece was a piano improvisation which was recorded via midi
and used a M-Audio keystation 88es, pianoteq 3.5, and sonar 8.5.

Once recorded the improvisation was heavily edited -  mostly moving notes (not
times) and removing hesitations I judged to be too long. Also the tempo was
increased by two. One of the interesting aspects of this piece is that the voice
leading is starting to work and I stumbled upon a real progression with
resolution that occurs about 1:42. When playing this configuration the main
challenge was remembering the relationships of 17 ET mapped to a 12 ET keyboard
� for instance a minor 7th becomes a 5th. Many of the chord changes are abrupt
since I was moving a pattern of notes in a parallel motion up and down the
keyboard as a main generator of the piece. The piece has some decidedly
xenharmonic passages. The compositional choices lean towards a balance of
consonance and dissonance analogous to 12 ET common practice.

The MP3 is here :  http://micro.soonlabel.com/17-ET/daily20091203-piano-17et.mp3

The OGG is here : http://micro.soonlabel.com/17-ET/daily20091203-piano-17et.ogg

The score (at 8th note resolution) is here :
http://micro.soonlabel.com/17-ET/daily20091203-piano-study-17et.pdf


As a request - it would be great to have a tool that could take a piece like
this in standard midi notation and translate to the tuning actually used in some
xenharmonic notation with the input of the scala file. Does this exist?

Thanks,


Chris

This is one of the most enjoyable 17-ET pieces I've heard in
a long time.  Thanks, Chris.  You're only using a few chords,
but you're using the right ones! and the soft piano timbre
takes care of the rest.  It still has some improvisatory
hesitations to my ear, but hey, nothing's perfect.

Thanks for the listen and comment Carl.

I agree that there are some hesitations left. Corrections can only go so far
honestly. A better performance is the goal eventually.

Subject: Scala sequence file note frequency in hertz?

mdevelde

I'm bussy writing an algorithm that automatically generates Just Intonation chord progressions.
I've just finished the most simple form of my algorithm, it outputs a scala sequence file with notes specified in frequency between parentheses.
Like this for instance:
5280� note (505.679012)� 480
5760� note (568.888889)� 480

Now I thought when one specifies note (xx.xx) that one is giving the frequency in hertz to be played.
Yet Scala renders nonsense pitches in the output when I do "transform sequence to midi file", and I can't figure out why.
Am I wrong in thinking "note (xx.xx)" is for note pitches in hertz?
Or did I do something else wrong?
Or is this a bug in Scala?

Any help would be greatly apreciated as this one is driving me crazy.
I really want to hear the output of my algorithm.

Many thanks!
Marcel

Yes you are right.
Thank you!

I wanted to write the frequency in Hertz, but it seems that this can't be done in the "note" statement.
I've come up with the following solution by using the frequency statement:
0� frequency 300.000000
0� note c� 480
480� frequency 166.666667
480� note c� 480
960� frequency 250.000000
960� note c� 1440
2400� frequency 187.500000
2400� note c� 480
2880� frequency 266.666667
2880� note c� 480
3360� frequency 250.000000
3360� note c� 960

Works perfectly now :)
Will post the first algorithm and a few mp3 files soon.

The most messy code ever written (I'm not a programmer) but it's working :)
Here the first output of my algorithm for those interested.

http://www.develde.net/

It's completely random only following certain basic harmonic and modulation rules comming from my harmonic permuation JI theory.
The 5limit output is most interesting for now.
The 6limit output I still have to limit the permutations a bit in certain ways as right now it gives ugly chromatic voices making the melodies too hard to follow through all this random movement.
Will write more interesting and musical algorithms soon.

Why should absolute frequencies be better than frequency ratios?

Why should absolute frequencies be better than frequency ratios?

It was easyer for me to write the algorithm this way.
It modulates randomly all over the place and the ratios could get really big.
This way I don't have to do a lot of math for the ratios but simply use the previous chord to calculate the frequencies of the current chord.

Hehe yeah it looks weird indeed :)
Looks like Scala's sequence format wasn't ment for this. But the great thing about Scala is that even if it wasn't ment for something in advance there's usually a way to still do it! Love Scala!

I put an mp3 up on my site www.develde.net of the algorithm output which I optimised a bit just now.
It sounds like real music to me :)

Hmmm, .. I don�t know; I sttill think ratios allow much greater versatility than absolute frequencies do. For example, if we decide for a starting frequency of 90Hz and we want to use 166.6667Hz in the piece, then the first thing which comes to my mind is the fact that the frequency in question could be multiplied by 3 and therefore the entire ratio could be multiplied by 3, which would result in 500/270, and it�s just upon your own choice if you decide to write 500/270 or 50/27. Similarly, if the fractional part of an absolute frequency value ends with something like �142857142857..� or �857142857142�, then the first thing which comes to my mind (I mean, without any great thinking, it just pops up in my head) is that I can multiply the ratio by 7.

Yes you're right.
It doesn't much matter in the end.
Except, for ratios i'd have to use 2 variables to store it and work with it. For frequencies only one.
I have to work with a seperate permutation array anyway because of how the algorithm works.

Btw I'm making a php page where one can control many aspects of the algorithm, and hope to make many outputs available in several formats, also direct midi tuned by pitchbends.
In time hope to make a sourceforge project out of it where several people can collaborate on working on the algorithm.
Perhaps you'd be interested too? :)
I'll let know when I've gotten a bit further with it.

I am certainly interested. I wrote a javascript MIDI library a while ago actually that operates on data URIs and might be suited for this purpose, unless a free and easy PHP MIDI library is already available.

But seriously man, what are you doing here? I'd love to see this algorithm. It sounds great and I'd love to see if it can be extended to 7-limit just or tempered tunings as well. It seems like you have a predefined list of chords, and that you just move from each chord to a random adjacent one with a common tone, but with some rules (V always goes to I, etc) while figuring out the voice leading on the spot. It would be neat to extend that to some of the more interesting chords I like to use in plain old simple 12-tet.

The truly remarkable thing about this is that you have created a very clever algorithm for a computer to generate fluid-sounding and natural chord progressions, microtonal or not -- it would be nice to hear an explanation of how your algorithm works at least.

Hi Mike,

I am certainly interested. I wrote a javascript MIDI library a while ago actually that operates on data URIs and might be suited for this purpose, unless a free and easy PHP MIDI library is already available.

Ok great! :)
It's my greatest wish to work together with people on this.
I just did it in php now because i did a few things in it many years ago so was atleast a bit familiar, and php.net is a great help in figuring out how to write something.
But javascript is fine too.
I do belief that php also has a midi output 3rd party script, i one ran across it but haven't looked for it again yet.

But seriously man, what are you doing here? I'd love to see this algorithm. It sounds great and I'd love to see if it can be extended to 7-limit just or tempered tunings as well.

In time I think it can be extended to 7-limit, it's all about permutation rules.
For tempered tunings, it seems possible but the basis of the algorithm is JI. Take away the JI and there is no algorithm as it's all about the pure harmonic series and it's permutations.
But one can offcourse temper the output of the algorithm after it has generated the music.
�

It seems like you have a predefined list of chords, and that you just move from each chord to a random adjacent one with a common tone, but with some rules (V always goes to I, etc) while figuring out the voice leading on the spot.

Yes right now there's a sort of predefined list of chords, as there are only a limited number of permutations possible.
But no functional hamonic rules yet whatsoever :) These can easily come later though.
Also right now there's no use of octave equivalence, and it's not using all the permutations possible yet (will write more permutation possibilities soon), it's ony the first attempt to write some of my theory in an algorithm, and a rushed attempt.
Also right now it only does "pure" permutations but no combinations of permutations (which will expand the possible number of chords to almost infinite), as I don't yet know exactly how this works and how to make sense of it. I do know that the individual voices are very important and can think of some rules to allow infinite chords and octave equivalence while keep voices pure diatonic etc but it gets very difficult here, something for later.

�

It would be neat to extend that to some of the more interesting chords I like to use in plain old simple 12-tet.

It can do it :) But later.

The truly remarkable thing about this is that you have created a very clever algorithm for a computer to generate fluid-sounding and natural chord progressions, microtonal or not -- it would be nice to hear an explanation of how your algorithm works at least.

I'm making the website that explain the theory and the algorithm etc soon. (but first next few days I wish to impement a few more things in the algorithm and make a few more songs)

This is the one that generated the mp3.
Again, it's messy, incomplete and written fast just to give an output that I can hear soon. It's not a good representation of my theory yet.
Ohyeah and don't mind the variable names, i was feeling a bit silly :p
But I think it'd be better to wait a few weeks till i have the site ready that will explain everything in an easy to understand way.
And I'll have thought of good ways to work together with people on this.
Though if you allready have ideas and suggestions be free to share! :)

Subject: Justharm scale

piaguiscale

To tuning yahoogroup,

I already have the 12 Justharm major triad graph responses which are derived from Piagui scale parameters. They are great; eight of them (A), show the same appearance: periodic and ordained chord wave peaks.

The second group (B) shows 4 identical responses which differs from (A), they are periodic and ordained chord wave peaks.

(A) C maj, C# maj, Eb maj, E maj, F# maj, G maj, A maj, Bb maj.

(B) D maj, F maj, Ab maj, B maj.

I believe that the three Justharm scale variants will produce fine chords. Soon, several Justharm chord SOUNDS (triads, sevenths, augmented, diminished.....etc) would be given in a website, this way you could discuss this production.

I would like to send you the three Scala formats of Justharm I, II, III.

The response given below and D major, Ab major, B major responses are identical.

They show periodic and ordained chord wave peaks.

Soon: Triads, sevenths, diminished, augmented, etc chord sounds would be placed in a website to let you to listen them.

The following response and C maj, C# maj, Eb maj, E maj, F# maj, G maj, A maj,

Bb maj show periodic and ordained chord wave peaks.

Thank you

SORRY, THE CHORD WAVE PEAK RESPONSE OF F maj WAS PLACED HERE BUT WAS DELETED. IT
IS A GOOD SIGN OF HARMONY TO SEE FOUR IDENTICAL GRAPHS FOR THE ABOVE MENTIONED
TRIADS. BESIDES, THEY SHOW ORDAINED AND PERIODIC DATA ALONG 4 SECONDS.

The following response shape correspond to C maj, C# maj, Eb maj,
E maj, F# maj, G maj, A maj, Bb maj; it is made of periodic and ordained chord
wave peaks.

SORRY, A SECOND INTERESTING GRAPH THAT WAS PLACED HERE WAS ALSO DELETED. IT IS A
PERIODIC AND ORDAINED INFORMATION ALONG 4 SECONDS. THE 8 MAJOR TRIADS MENTIONED
ABOVE SHOW THE SAME KIND OF RESPONSE SO IT IS VERY PROBABLE THAT JUSTHARM SCALE
IS BETTER THAN PIAGUI SCALE.

I THINK THAT I CANNOT SEND DIAGRAMS.

This study entailed learning how to simultaneously play six instances of z3ta+
in 19-ET tuning with my Fender Mustang using a Roland GR-20 as the guitar to
midi interface.

Shouldn't the array be sorted at this point?

Anyway, for whatever it's worth, I re-wrote the script in
Python:

I don't know if it's working right but it outputs something
that looks valid.

Hi Graham,

Shouldn't the array be sorted at this point?

This part only checks wether the lowest voice isn't lower than the given $low_freq and then if the highest voice isn't higher than the given $high_freq
If one of the voices in this chord is indeed too low or too high it simply does $i-- and starts building a random chord again, this loop continues till the chord "behaves" and isn't either too low or too high anymore.
I set the $low_freq to 73 hertz and the $high_freq to 940 hertz because the choir sound I used doesn't go any lower or higher.
I have no idea what sorting an array means :) I'm not really a programmer as you can see hehe.

Ok wow thanks, and congratulations you could convert it.
I'll go figure out how to run a python script later today.
To check the output simply copy paste it to a scala sequence file and use scala to convert it to a midi file.
(btw if you're running the php version in a browser you need to look at the generated page source and copy paste this)
The .scl file only needs a head. I used this one:

0�� exclude�� 10
0�� tempo�� 120 pm
0�� velocity� 96
0�� frequency 261.626
0�� notation� E12
0�� text "Harmonic Permutation JI Algorithm Output, Marcel de Velde, Zwolle, 8 dec 2009"
!

Below this paste the output of the algorithm and it should give random music.

btw I'm curious what the sorting of the array does in your script.
And why did you think it was needed?

Marcel

It makes sure the first note in the chord is the lowest,
and the last note is the highest.  I don't see how else
this is done.

I'll look at other things tomorrow.

and the last note is the highest. I don't see how else
this is done.

It is allready the automatic result, no sorting needed for this.
There are several ways to write the permutations I wanted, but I wrote it the way that first the permutated chord is built, and then the whole chord is pitched to the correct frequency.
The php script I posted works perfectly (as long as one doesn't set an impossible low or high_freq or voice1 start frequency)
It is the exact code that generated the output I made the mp3 of that I posted.

I believe I've seen this before.

Hey Carl,

Either I'm just now aware or you are certainly right about the convergence
around microtonal instruments.

Micro IS the future - but I'm preaching to the choir.

Good day,
