Dear Prof. Dr. Jason Yust:

You might enjoy https://81018.com/grok-3/ as a follow-up of my two earlier emails.

Remember how you said, “Each Fourier component measures an independent musical quality: (1).chromaticism, (2).quartal harmony, (3).triadic harmony, (4).octatonicism, (5).diatonicism, (6).whole-tone balance.” Grok-3 is a start. I believe in time we will have a geometry and further applications of Fourier for all six components of musical quality.

Thank you.
Warmly,
Bruce

Dear Prof. Dr. Jason Yust:

Your work on the Discrete Fourier Transform within music theory came to my attention and pulled me in deeper and deeper. Nicely done. Inspiring. Also, “Congrats” on your Brown start. I wonder if you ever took a class with Phil Davis in applied mathematics. Phil was my go-to person on spheres!

Also, roots of mine go back to BU. First, with Robert Cohen and Marx Wartofsky in the physics department, and then Harry Oliver and J. Robert Nelson in the School of Theology.

I am developing a resource page of links to your work and it will be here when its done: https://81018.com/yust/ (this page)

My orientation has been called idiosyncratic, notwithstanding, here are very different orientations that you may appreciate:

  1. There are 202 base-2 notations from the first moment of time (assumed to be defined by Planck’s units of time and length).
  2. All notations necessarily appear to be active refining space and time, and the finite-infinite relation.
  3. If so, the first 64 notations are below all possibilities of measurement.
  4. I am in the process of introducing a “geometry of the gap.” It’s the place where quantum fluctuations are measurable. Here are a few more references: https://81018.com/icosahedron/

    https://81018.com/15-2/ and http://81018.com/gap/

Thanks again for all that you do.

Warm regards,

Bruce
