Experimental Music Consideration

Future Music Room

I introduce Strange music, imaginary music, and experimental music in this section. Some information is from classical music. Why future? I do not know, sorry...

Kepler's Planet Theater	The Kepler's imaginary world is reproduced with JAVA and MIDI.
Mandelbrot Theater	Mandelbrot picture is drawn with music. It needs fast CPU .
Cats Symphony Orchestra	Cats sing with random pitch.

Kepler's Cosmic Harmony
(the music of the spheres)

I saw a planetarium show and I found an exhibition of "Kepler's music scale of the planets." I was interested in it, and I gathered information from mailing-lists and web sites.

Kepler was trying to find common rules between music and planet's movement. His harmony of the spheres is based on the relative maximum and minimum angular velocities of the planet measured from the sun. (It is not a music scale in the strict sense of the word since the sound is continuously changing like choking or sliding.) As the planets move in their orbits their velocity is lowest when farthest from the sun and highest when nearest to it. The increase and decrease of speed correspond to the rise and fall of sound that planets produce. The range of sound that the Venus can produce is very small, since its orbit is almost a perfect circle.
In such a manner,Kepler allotted to the planets the musical intervals.

Saturn	G1 A1 B1 A1 G1	MIDI Data
Jupiter	G2 A2 Bb2 A2 G2	MIDI Data
Mars	F3 G3 A3 Bb3 C4 Bb3 A3 G3 F3	MIDI Data
Earth	G3 Ab3 G3	MIDI Data
Venus	E4 E+4 E4	MIDI Data
Mercury	A3 B3 C4 D4 E4 F4 G4 A4 B4 C5 A4 E4 C4 A3	MIDI Data

The six planets produce six notes and at the most time, they creates disonant. However, they can be consonant at some point within a long time. Kepler called this "music of planets." The music encyclopedia "Grove" says that it may have happend only ones, perhaps at the time of creation. We can listen to this harmony if we make time go faster. The interval between the Earth and the Venus makes a consonant, so Kepler thought these planes were a hasband and a wife.

Hauer's chord generation mechanism

The oldest algorithmic composition which uses random number might be dice music of Morzart. However, this is just a mechanism which changes arrengement of patterns(measures) and has no other composing mechanism. Autrian musician, Hauer deviced a mechanism which generates chord from random numbers and some rules.

Mandelbrot Music

Mandelbrot is the name of French shcolar who used the word "fractal."Fractal is a word that is used to describe characteristics of figures. When a part of Fractal figure is magnified, it appears as the similer figure of original one. Wnen that part of figure is magnified, it also resembles original figure. Although Mandelbrot figure seems very complex, Mandelbrot set was defined by a simple equation. Zn+1 = Zn*Zn+a (Z0 = 0) Z and 'a' are complex numbers, and the set of 'a' where |Z(n)| does not diverge infinity is called"Mandelbrot set"
Mr. Yo. Kubota developed a software tool that generates music tunes from mandelbrot set. His web site provides the tool and source code.

I made a page that displays a mandlbrot figure with mandelbrot music.I modified free source codes that is provided at web site, "Fractal for Java Applet."

Music from the Nature

Things from the nature heals people's mind. Ocean waves, wind sound are example. So, some people tried to extract music seed from data of natural things. I made a program that generates music from Japanese land data.

Links to Experimental Music Site

T's Garbage Factory	The site provides a freeware that reproduces Kepler's imaginary world.
The Sound of Mathematics	This site also has Pi music as well as other music from Mathematics. Information is in English.
Strange Music Archives	This site introduces Mandelbrot Music. Iteration values of Mandelbrot Set are changed to music by a composition rule.
Earth boys	You can listen to strange music with real audio.
Pi is music	The author of this page allocated music notes to the numbers of pi, 3.14... Unfortunately, information is in Japanese. Go to the site and click numbers with red color, you will listen to strange music!
Fractal Tune Smithy home page	There is information about fractal tune.
