THE DOWSING POLES- New instrument member of the Meta-Slendro Ensemble

The Dowsing Poles This instrument grew out of a desire to have something like Tubular Bells to add to my ensemble of Meta-Slendro instruments. This tuning is anything but a conventional Slendro encompassing instruments using 12, 17 and 22 unequally spaced pitches in the octave informed by both traditional sources and recurrent sequence mathematics. 

In order to realize such a Tubular Bell instrument and after much experimentation, I decided to explore the possibilities of suspending the tubes in the middle instead of the conventional nodes used on all my other instruments. This produces a somewhat similar sound to the desired orchestral instrument but with even more pitch, making the use of small distances between some pitches in the tuning much more practical and realistic.

Mounting the bars in this fashion was extremely difficult as it a point of balance, but wanted the tubes to be vertical in order to take up less space and easier to play. The present method of tying elastic cord seems to work well but am still not cutting the cords quite yet in order to see how it works after at least a few weeks. Hence why they can still be seen for the time being. This instrument is also quite modular being usable in any or all of the three sections and it allows the tubes to be placed in any order of which is shown here. The sections themselves are also flexible in being placed in a chain of any configuration here conforming to the only flat section on the Anaphorian Embassy grounds. This instrument will get it premiere at the Now Now Festival this Thursday night at 107 Projects

Speaking on Erv Wilson.

Here is an excerpt of what i had to say on reflection on the work of Erv Wilson. This is an extract from Stephen Taylors' Sonic Sky

A family of 9 tone Scales with some 14 ones on the side.

We have to thank John Chalmers for his Tritriadic Scales. It causes us to keep focus on the material generated by the combination of tonic, dominant and subdominant and how wide those parameters can be extended. It seems to be an idea that has been in the air recently. Warren Burt used in an installation, which you can listen to a bit here 3 11-limit harmonic series fifths apart. Such a structure while embedded in a Partch diamond (harmonic hexads on 1/1, 3/2, and 9/8) seems to stand on its own with it own life. The piece I am working on now for solo vibraphone that I will be playing in Brisbane and in Helenburgh explores these relationships within 7 tone scales much in the way Indonesians will use pentatonic within their 7 tone pelog. I mention some ideas about this here in relation to the idea of tempering to accommodate these three scales.
It appears it a similar idea caught the interest of Steve Grainger who took a classic 7-limit Pentatonic and extended it likewise up and down. This he mailed to me.
I made a mistake right off and assumed it was not a “constant structure”, that is a scale that where each occurrence of a ratio is always subtended by the same number of steps. It is a quality that gives a good melodic flow that otherwise only has harmonic relationships holding it together. Having both is worthwhile to pursue.
But I moved ahead and found 2 solutions right off for 14 tone scales. It is an unusual number to have as a scale and I seem to have come up with quite a few over the years. I am not sure why. These are illustrated and one could pick out of either set of alternatives depending on what one might like.

There is an important feature here though of Grainger’s 9-tone scale that as far as I know has been overlooked. It appears that there is a whole family of pentatonic based on 3 fifths plus 2 notes in between the fourths that will all produce 9 tone constant structures. These tones have to be larger than a 9/8 but smaller than a 32/27, most of your smaller minor thirds.

This scale would have been of interest to Rod Poole and note sure if La Monte Young has toyed with the idea, since it develops in the direction of 3 and 7s. It is in that territory

Prelude to a Whirlpool

Thanks to Mike Cooper for putting this up who work can be found linked to this video. A very early show of Chris Abrahams and I and early in the set. Perhaps turn down the volume a bit if it distorts. It is not easy to record such thing off the cuff. It has evolved quite a bit since here and even the instruments have changed color:)
