Tell me if you have information about fibonacci number with

[tony]

Hai guys I need information about music and number especialy fibonacci. I need information because Iam interest with proposition for duration in a composition . thanks

I've been looking at Prime Numbers myself, and I've been even more interested ever since I learned about Ulam Spirals: http://yoyo.cc.monash.edu.au/~bunyip/primes/primeSpiral.htm. And since I was never great at math but always interested in patterns, I've been doing really simple things like summing digits, looking at the number 9:

1+2+3+4+5+6+7+8+9=45, 4+5=9
1*2*3*4*5*6*7*8*9=362880, 3+6+2+8+8+0=27, 2+7=9

I'm going to take the prime numbers and sum the digits down to numbers 1 thru 12 and then play the notes and see if anything interesting shows up.

i've been playing around with these kind of things too:
example: create new integer array..
and each iteration, new value of each cell can be calculated from adding some values from the array.

for example: new x[n] = old x[n] + x[n-1] .. (the index can wrap around the size of the array)

This was quite fun. Here's what I did:

First I used a cellular automaton program to generate a 2D pattern (time evolving down the screen), using the maximum number of evolutions. I copied each batch of evolutions and pasted them all into paint so they formed a very long continuous image. Then I rotated it onto it's side and ran it through a bitmap to sound converter.

I tried that with a few different types of 2D automata and one of them (which kinda makes continuously branching and wrapping triangles) has a nice rhythmic pulse to it which I want to use in a song soon.

Of course, I've tried it with fractals but it's pretty lame that way. Unless you never tire of hearing "sppluuuurrgeeeweeemp"

i am interested to here more about your composition idea. when playing with numbers it seems how you employ the numbers is most interesting to me. generating an array is one thing, but exploiting it is another . . .

i.e.--absurdist lover's method which is awesome!!!

turning the numbers generated into graphical form
rotating the graphical form to make it parseable
parsing not the numbers but their graphical representations
only taking in what sounds good to the artist, in this instance absurdist

i think john cage used the i ching and chance operations to determine duration in some of his pieces, well worth a look, or a listen if yur lucky
