Some Time Alone 17 edo

Some Time Alone for 17 edo guitar. A lost post from 2011

As the title says I spent some time with my 17 et guitar. I purposefully tried doing non-12 sounding stuff with what I think is moderate success. I believe I will have to resort to some “dots” to get some new scales in 17 et down – there just is too much to keep track of when I change strings causing the patterns to be transposed. I apologize for the sloppy classical guitar – ish playing.

Piano Exercise in 17 Notes per Octave (August 2016)

17edo_august

This Piano Exercise in 17 Notes per Octave (August 2016) is another in my series of writing something playable for a piano student that has modest skills in a microtonal tuning. The score is purposely scordatura because I think that notating in various microtonal accidentals is simply a burden when a person with a 12 equal midi controller and microtonal aware sound source set to 17 notes per octave (like a free Xen-Arts VSTi) can simply play the score as if it was written for 12 equal but the sound will be in 17 equal and produce the microtonal music of the score. The composition is somewhat free form with development.

The full score is here. Academic performance in a setting where a fee is charged is allowed. Any other commercial use without my permission is not. Please write me for permission in such a case, I haven’t told anyone no as of yet 🙂

Below is an animate score version

Red Sands Maunsell Forts

Redsandsforts

Red Sands Maunsell Forts is quasi-ambient piece constructed from loops taken from a 17 edo guitar improvisation and the subsequent loops processed and live sequenced using Sonar’s matrix view (the graphic below). While it doesn’t have the flexibility of Albelton Live, I find the the constructs to be interesting despite being laborious to set up.

Aeolian Edit 2 (17 edo)

aeolian_edit_2 Click graphic to see the tuning and “score” in the melodyne screen capture.


Aeolian Edit 2 is an experiment with manipulation of an electric aeolian harp sample which I added counterpoint and retuned to 17 edo (equal division of the octave). Since the electric aeolian harp yields only harmonics what has been manipulated are the pitch values that the melodyne detection routine decided were root pitches and *not* harmonics. By retuning to 17 I have recomposed the original content into something other than a pure harmonic relationship. My apologies for the large volume changes – in this case I’d rather have close to a constant loudness but do not have that worked out yet.
