A 22-tone Diaphonic Scale

 This is a rare occurrence of Wilson presenting a Diaphonic Scale in its Harmonic over it Subharmonic form. Other Diaphonics scales are presented in the first section of the Wilson Archives and one can also find a comment of Diaphonic scales. The two pages have been edited placing the two charts together to allow them to be viewed easily at the same size.
A PDF of these pages is available here.

A Double Bosanquet Keyboard or the 2/7 keyboard

I have to thank George Secor for posting this keyboard. It illustrates how one might introduce doubled rows [running bottom left to upper right] to accommodate such tunings as using the half fifth as a generator.
Later Erv would relabel this keyboard the 2/7 keyboard as seen on page 8 of http://anaphoria.com/gralspectrum.pdf . One can see how then the generator lies in the half of 3/2 range.

Nothing can thrill us more than announcing the launch of this web documentary on the work or Erv Wilson.

Hobo Coffee

In a letter from Erv the other day, he found it important that the recipe for Hobo Coffee he learned from Partch be included in the Archive.

Black Coffee
(one) whole Cardamon seed.

Since Hobos could not carry milk the cardamon seed was the replacement

A lucky accident concerning some non octave scales

 I happened upon two different Wilson documents which where quite separated but i had viewed recently enough to remember and realized their relationship which are  presented below.  First a letter which i assume was to Brian McLaren followed by the paper in Novaro referred to. The third is Wilson respelling of the two points in a scale tree type way that shows the relation of novaro's ideas to this series. It was lucky enough to stumble upon some time before and showed Erv how Novaro series can be generated as a Pascal triangle or in a series like this. He ran with it.
It also explains some of his other division of a tetrachord in a like fashion. The method shows a quite way of generating non octave structures.

Hexany Voicings

 

Here are two papers of Erv working with different voicings of the hexanies based on the simplest set of 24 permutations. He often thought of such held chords as sound sculptures and we can see in his notes his subjective responses they invoked as he played through them .

A System of Color Coding.

I quite remember the set of hebdomekontany bars that Erv refers to here but did not realize how he had determined the color coding he used.
