Most people and musicians do not know that more than 90% of what they learn in music theory is useless.

Music theory and its notation system are the result of a long construction process over the centuries, to which composers and musicians have contributed a wealth of concepts.
This slow progression has unfortunately not made it possible to question the foundations that were laid down in Antiquity. Indeed, all conventional music theory is built so as to give preference to notes and musical intervals that are pleasing to the ear.
In this way, without realizing it, musicians arbitrarily selected seven out of the twelve notes that exist in music. After that, in order to indicate the five “lost” notes, it was necessary to create an extremely complex system of corrections- using sharps and flats.
On top of this, there is a more serious problem. The notes that were chosen in the C-major scale have irregular intervals.
The structure that they make up is just one possible variant. The fact that this particular scale has been used as a reference has led the entire concept of music theory to be constructed on just one sample of music!

It is this sample of music that is seen through five lines on music scores or piano keyboards. This absurd situation can be compared to an author being forced to write his books using the same sentence structure throughout. So, without even knowing it, musicians and composers continue to annotate and correct this imposed sample of music to create and play their work. The immense complexity of this notation is nearly infinite and makes it necessary to gain, year after year, an enormous amount of knowledge that is, frankly, totally useless!
However, this is not inevitable. Dodeka is the proof that a language made up from the “alphabet” of music can make it clear and accessible to everyone.
This return to the real base of music gives proper emphasis to all twelve notes and makes it possible to freely create the various structures that make up the scales and chords.
Not only does the awareness of musical architecture make it much easier to learn music, but it also makes it possible to understand how music interacts so delightfully with human emotions.
