Hamburg Music Notation
Hamburg Music Notation is an Alternative Notation based on numbers. We started this blog to inform you about this notation system, discuss new developments and stimulate interest in the software that we developed as Partner of Arpege Music. http://www.arpegemusic.com/alternative-music-notation.htm. Please feel free to comment and to ask questions. Our booklet “Numbers are Music” by Robert Elisabeth Key published with kindle contains more detailed information on this subject.

Your site is very interesting. I thought by myself before, there must be better ways to write down music, and here I found an example for this. You use numbers 1,2,3…A,B,0. Is it difficult to learn and think in a dozenal system of numbers?
It is not difficult to learn but to get the knowledge to a subconscious level takes a lot of practice.
Most of us are only familiar with decimal counting.
How can I get help in the internet with the dozenal system? Is there a community for dozenal counting?
There are two dozenal societies that I know of:
1. DSA – Dozenal Society of America http://www.dozenal.org/drupal
Section Articles and books gives a link to
Music, Scales, and Dozens by Dr. John Impagliazzo
summarized there: Dr. I. methodically examines the Pythagorean, Just Intonation, and Well-Tempered (dozenal) music scales and illustrates their differences.

The very interesting list on dozenal applications http://www.dozenalsociety.org.uk/apps/appslist.html
contains an article

What can one do to promote Alternative Music Notation Systems Based on Numbers?
We can see in this web http://musicnotation.org/tutorials/numerical-notation-systems/ that there are around 10 other music notation systems based in numbers (12 numbers), Your system is a slighly variation of them, being 2 or 3 almost identical to your system, (Carrillo and Kuncze). Can you tell me what part of your system can not be used for “comercial” means? and what do you mean with “comecial”?
This is an interesting page about alternative music notation. It seems to be an easy way to write down notes and melodies.
