<!------------------------------------------------------------------------
This piece consists of an actual composition, which may include a Csound
orchestra, WebGL, a GLSL shader, JavaScript for generating scores (perhaps
using the CsoundAC library), controls for the user to adjust the settings
of the piece or to control it in real time, license information, and
program notes. These are the parts that need to be written to create a new
piece.
There is also much "infrastructure" code that sets up the user interface,
compiles the Csound orchestra, compiles any GLSL shaders, and handles
all events from the user interface. Most of this code requires little or
no change when writing a new piece.
Non-infrastructure code, the code that makes a piece, can be found between
the lines marked >>>>>>>> and <<<<<<<<< below.

<p>This is an online piece of electroacoustic music, rendered in your Web
browser using high-resolution audio. It will play indefinitely, never ending,
always changing.
<p>This piece is generated as a sort of musical dynamical system operating in
chord space. Generated notes are sent to Csound for rendering in real time.
The synthesized audio is then sampled (using a WebAudio Analyzer) to generate
a sine-wave visualization of the music, using code adapted from <a
href="https://www.shadertoy.com/view/4ljGD1"><b><i>Sound Sinus Wave</i></b></a>
by <a href="https://www.shadertoy.com/user/Eitraz">Eitraz</a>.
<p>The notes are played by a Csound orchestra that is embedded in this Web
page using my <a href="https://github.com/gogins/csound-wasm">WebAssembly
build of Csound</a>. This in turn includes my
<a href="https://github.com/gogins/csound-ac">CsoundAC</a> library for
algorithmic composition.
<p>Feel free to use this piece as a template for creating new pieces of this
type... as long as it doesn't sound too much like this one!
<p>Please report any problems you have playing this piece, or any ideas for
enhancements, at <a href="https://github.com/gogins/cloud-music/issues">

<h2>Credits</h2>
<p>The StrangeAttractor class in CsoundAC, which computes the 4-dimensional
orbit of a system of 4 coupled ordinary differential equations, uses code
inspired by Julien C. Sprott's book <a
href="https://sprott.physics.wisc.edu/fractals/booktext/SABOOK.PDF"><b><i>
Strange Attractors</i></b></a>. The state of the system is mapped to indices
of set-type, inversion, pitch-class transposition, and octavewise revoicing.
In short, the chaotic orbit of this system becomes an unceasing flow of chord
progressions.
<p>My code in CsoundAC for working with chords, scales, and voice-leading
implements basic ideas from <a href="http://dmitri.tymoczko.com/">Dmitri
Tymoczko's work in music theory</a>.
<p>Code for compiling and controlling shaders is adapted from <a
href="https://www.shadertoy.com">ShaderToy.com</a>.
<p>The algorithm for downsampling the video canvas is from <a
href="https://skemman.is/bitstream/1946/15343/3/SS_MSthesis.pdf">Sveinn
Steinarsson's MS thesis</a> with code from <a
href="https://github.com/pingec/downsample-lttb">
https://github.com/pingec/downsample-lttb</a>.
<p>Csound instruments are directly copied with minor alterations from <a
href="https://github.com/csound/examples/blob/master/csd/xanadu-high-resolution.csd">
Joseph T. Kung's Csound piece <i><b>Xanadu</b></i></a>.
