>>17473471House is a genre of dance music with a focus on repetitive beats that harken back to disco and soul music. Trance is similar, but usually has a faster BPM with a focus on atmospheric sounds that builds into a big drop. DnB has a focus on layered drum patterns and samples that contrast the underlying deep bass. Basically, it just has a crazy amount of percussion to make up the song. I can't really tell you much about techno and electro.
