New genres simply start with either some musician mixing the features of some other genres or a group of musicians. Then, musicians combine them with specific themes. However, to be called a new genre, it should have a certain number of listeners. Until magazines or music historians give it new fancy names. To spread the new trend of music, the music industry needs to have a name. So, music comes from everywhere, anywhere and so do the names we call it by. It has been shown for many examples that pre-existing knowledge bases shape the direction of innovations. It appears to be more likely for a new industry or technology to emerge in a region, when the region is specialized in industries that are related to this industry. For example, rock and roll came out of the US, which had the biggest industries and technologies. It came out with mixing "black music": blues, rhythm and gospel music. Then it had it’s golden time in the 60’s and early 70’s in England which also had one of the biggest industries of its time and naturally it was one of the most innovative times of creating new genres.
Briefly, new genres of music are always made with the help of other musicians. Musicians gather musical ideas from the day they start to listen to music and they make new kinds of music that reflects themselves better. Furthermore, this is valid for all kinds of art. Because everyone is different and art is the way to express human emotions. Every expression is a little bit different from others which creates new ideas, art movements and genres. Authenticity is invaluable; originality is non-existent. Film director Jean-Luc Godard once said
“It’s not where you take things from, it’s where you take them to."
