With this existing database, and using Tulip for the heavy lifting, Anonymous Prof was able to map the relationships between 444 classical composers starting from Hildegard in 1098 through the present day.

What we see here is a 3D representation of the 444 composers. Each white sphere is a composer and each line represents a connection. For this visualization, a connection represents a point of influence. In other words, every time The Classical Music Navigator indicated that composer A was influenced by composer B, a link was created. The size of the spheres represents the number of direct influences that a composer has had. This resulted in 2,618 direct relationships. The bluer the line the younger the composer (bottom) and the redder the line, the older the composer (top).
