I would like to thank my friend Larry for the loan of the guitar. I always wanted to know a semi-hollow was good for feedback. I can answer with an emphatic yes.

### Tesseract – Adaptive JI Acoustic Guitars

Saturday, February 13th, 2016

The copyright holder of this (graphic) file, Robert Webb, allows anyone to use it for any purpose, provided that the copyright holder is properly attributed.

Tesseract is a recomposed piece that started life as an steel string 12 equal acoustic guitar improvisation trapped in an unpublished video. I extracted the audio track and then brought it into Melodyne 4 Multitrack. Once there I duplicated the track and transposed the duplicate up a fifth creating a lot of lush harmonies. Then to polish the harmonies I selected both tracks and applied Melody 4’s adaptive JI algorithm. Applying adaptive just intonation to the combined tracks is crucial to allow the programming to operate on the newly created fifth relationships. Lastly I panned the two tracks left and right.

### Being Califlower (12 equal – ImprovFriday mash)

Sunday, February 7th, 2016

Being Cauliflower (feat. Shane Cadman, Chris Vaisvil, Jude Cowan and mashed by Steve Layton) – Nearly every musician has had the experience where they join in a free-form unplanned improvisation and magic happens in the room as everyone seem to pull their parts from the air and make a cohesive whole. As one who has experienced that I have to say it is an awesome feeling of being “plugged in”. What is even more incredible is when this happens when the respective musicians can’t hear each other and separated by hundreds or thousands of miles across the internet. Steve Layton in 2012 took a number of separately recorded tracks for the then ImprovFriday (now sound-in.org) and put them together with little editing and the result is one of my favorite collaborative tracks “Being Califlower”. I hope you enjoy it as well.

### Nail the Jelly to The Wall (12 edo)

Saturday, January 23rd, 2016

Singing and original melody by Christiane Offenbar
Words by RichardLeach, Jan 4, 2016
Arrangement by me – in 12 edo

The calendar says Monday but it doesn’t say what for.
You hear a nearby ticking and you hear a distant roar.
You get up when you hear the bugle call.
You have to nail the jelly to the wall.

The galaxy is spinning but it doesn’t fly away.
Dark matter holds it all in place, at least that’s what they say.
You hear the running in the upstairs hall.
You have to nail the jelly to the wall.

You try to play your tenor but you have a broken reed.
The overtones are hidden and the undertones are freed.
Sometimes a tower leans and will not fall.
You have to nail the jelly to the wall.

### Farewell 2015 – Just Intonation and12 Equal pieces

Click picture for scala file

Nordic Influence is a classical guitar piece recomposed from 12 equal to Scott Dakota’s Nordic Folk Music Just Intonation derivation

2015 fades into history is a pairing of many synthesizer pads with a plaintive acoustic guitar strummed into the past, 12 equal tuning.

### Quantum Mechanics (poly-tuned)

Friday, February 6th, 2015

Fig. 1: Probability densities corresponding to the wavefunctions of an electron in a hydrogen atom possessing definite energy levels (increasing from the top of the image to the bottom: n = 1, 2, 3, …) and angular momenta (increasing across from left to right: s, p, d, …). Brighter areas correspond to higher probability density in a position measurement. Such wavefunctions are directly comparable to Chladni’s figures of acoustic modes of vibration in classical physics, and are modes of oscillation as well, possessing a sharp energy and, thus, a definite frequency. The angular momentum and energy are quantized, and take only discrete values like those shown (as is the case for resonant frequencies in acoustics)
