64 notes for Piano minor scaled opus 1 released

Here is the first release of a series that will be created and performed created and performed with the use of the cannon maker project concept software.

"64 Note for Piano Minor scaled opus n1"



This is the first page of this compositions sheet music.




Also I have included the sheet music to this composition So other have the chance to perform it with there own ideas and style..

More on theory of creating canons in computer generated music


After posting on the concept of creating the same forms you find when scoring a canon but in computer generated music system. I revised a email on the subject. I thought it was a interesting view on the subject. So I thought I share it with the readers of the blog.

The response was sent by “Bohgosity BumaskiL

Changing quarter notes to eighth notes, and the rest of the notes in the
same proportion is the same as changing tempo. Similarly, scaling pitches up
or down (multiplying all pitches in hertz by the same frequency) will yield
an identical tune (in a different key). Augmentation is something you can do
to fifths and fourths without offending terminology purists. A perfect fifth
is 3:2. A classic augmented fifth is 25:16 (24:16 would be perfect). Your
use of "Diminution" is also about tempo. I am glad you are defining
inversion for me, because that is what I thot it means, and it provides
validation for a just intonation (tuning on the harmonic series) I promoted
in June (inverting it and scaling it by an octave work out to the same
thing, except on one key).

I've used fractint to get algorithmic music. Some of the best of what I've
heard comes from a "hopalong" fractal. It was called "the wizard".
Unfortunately, fractint works best under DOS, and I hav not even tested
whether winfract does sound. It does not handle skew, among other things.

One of my criticisms of fractint is that it adheres to 12TET, and I do not
know what to do about that. The alternative is perhaps as simple as scaling,
adding, and rounding. Perhaps I can add a third way for fractint to quantize
pitches. The first way is NO quantization, and I will hav you note that "The
Wizard" is quantized -- in a weird way, though: All of the quantizations are
powers of two.

The connection between Musical Scales and Modular Arithmetic



Pythagoras' musical scale is based on a geometric sequence and can be viewed as a type of modular arithmetic. Whenever we get out of the ratio interval 1 to 2, we divide by a power of two to find out the corresponding number within the interval.

In Pythagoras' scale the ratio of 3:2 corresponds to the fifth note (V) in the scale.

Looking in terms of the scale numbers,since note VIII is like the first note I, we can view the numbering of these scale notes has a modular system with modulo number 7 just like how a clock is a modular system with a of modulo 12.

Understanding that we can identify the first tone I with 0,II with 1 …, VII is 6.
Therefore the tone ( V ) is adding 4 and modulo 7. Understanding the way modular arithmetic works and it's direct connection in the way scales are shaped. Can lead to better computer based scale creation systems.
