No protection of musical styles, musical theories, etc.

In the same way as the idea or the thought itself do not enjoy any independent copyright protection, rather only when these are cast in a form which is perceptible to the senses, a special musical style (e.g. blues, classical music, jazz, techno, etc.) or a musical theory alone is also not a legitimate work in itself. That means that a newly created musical style can also be used by others and further developed, for example, without requiring any consent (cf. a rather old but extremely good decision of the Federal Supreme Court: BGE 70 II 57 et seq. for further information).
