Thanks for sharing, it is interesting to hear. The tuning system is
quite unfamiliar for me, but would it be correct to say that with this
many subdivisions it approaches a continuous pitch field?
In the section starting at 9:20 is sounds as if there is a pitch bend,
but perhaps it is just a result of the density of the tuning system
and the way that chords are clustered, releasing some notes will let
the whole chord (perceptually) "slide" in pitch?

Very nice!

Both the intervals and structure of different densities. How did you construct the scale?

Dear community,

during the last weeks I've made experiments with 53 pitches per octave.

On https://soundcloud.com/stefan-thomas-6 You can listen to an improvisation I've made at home.

I use a piano-like sound, made with FM synthesis, created with csound.

With the help of a midi foot controller I was able to change the register.

At the end I use multitap-delay extensively.

Hope You find it interesting.

As I mentioned, it is an improvisation, with an concept, but mostly intuitive.

I'm going to make an exactly written composition out of my ideas and this material.

Any suggestions,annotations and comments are very welcome, no matter if they are critical or encouraging.

It has quite a history. This page discusses the maths of the whole sorry 
business of e.t. tunings, and via a brief detour via the Golden Section 
eventually celebrates the insufficiently sung hero of 53-note e.t., King 
Fang, ca 40 BC:

He says he will be talking about tuning of pianos and I thought he was going to mention the inharmonicity of piano strings, but he didn't.

Yes indeed, I assume he is writing primarily about the maths, and the 
problem of stretched octaves etc would add inconvenient complications 
which would obscure the core mathematical issues of temperament.

For stretch tuning the canonical reference is the proposition of Serge 
Cordier to tune the piano using an e.t. division of (pure) perfect 
fifths, giving a systematic stretching of all octaves. A modern web 
reference is here:

http://www.pykett.org.uk/impureoctaves.htm

I have somewhere the original typescript document produced by Cordier, 
who presented it a long time ago at the Menuhin school, including a 
performance demonstration with a string quartet (strings tuned in 
perfect fifths, giving a particularly clean blend with the piano). I 
have no idea how widely this method is adopted by working piano tuners, 
however.
