People have always sought to systematize the music, breaking it down into genres and sub-genres. The main method of this systematization has been and remains the “historical” method, which can be described as follows:
A worker K, which plays music similar to the genre of L, but obviously this genre doesn’t fit. The artist or music. critic, the label come up with that kind of music, a new genre, the genre L – LL. And after R years genre LL becomes canonical. Or not getting, depending on the results of the “test of time”. Thus, all musical genres can be combined into graph in which the genre L closer to the root, and LL – to the leaves.
This method is historical, because the rules always came after the main genres. I.e. this method illustrates the development of music, its evolution. But this graph is not quite correctly illustrates the relationship of genres with each other-see a musical point of view. I.e. from two completely different musical styles, different eras can appear subgenres which are so close that a significant number of musicians as their “brands” to indicate both genres. But in the “historical” graph, they are unlikely to be nearby.
Moreover, due to the high degree of subjectivity and complexity of the historical method, there was no single “tree of genres”. As far as I am aware, there are only separate successful attempts to build a graph on the level of individual groups of close genres.
There is an alternative method of ordering, which does not have these disadvantages. To describe it this way: There are M artists playing music that falls under the canonical 1-4 musical genre. Genres are connected by an edge if both combine genre was found in the creativity of one artist. The more the artists are crossing both genres, the closer their nodes are to each other in the final graph (shorter edges). The more often the genre found in General, the larger will be its node in relation to the others.
Some observations: Kraut Rock, was far enough away from “fatal” constellation, and ended up in the experimental area of the graph, and the father of Post Grunge was Metal, not Grunge. Also no one genre was not in the center, the overall shape of the graph is rather similar to a donut (ring).
I assume that comments will be a lot of criticism. Some of this Earl seem untenable. Take it easy, this graph is only a concept to illustrate one of the variants of the methodology for determining the formal relationships between musical genres.

About the project
Source of data on artists and genres was the Music widget. The principle of the service: the user chooses the performers that are personally interesting to him, and when someone of them will release a album or single — the user will receive a notification via E-mail. No quizzes, advertising, promotions, notification about new releases.
