Huh, I watch that and chuckle at how dated it is, and totally missing the point. Should we all point and laugh at how "Why So Serious?" from The Dark Knight soundtrack isn't something you can sing in the shower?
And 12-tone music isn't the result of an especially "mathematical approach" to music. It's the result of the attempt to break the boundaries of the traditional tonal systems using the musical language that existed at the time. It's the primary endgame of atonality within equal temperament system. Traditional western music is all tonal. It's all in "keys." 12-tone music is an attempt to create meaningful, coherent music that avoids relying on tonality. It's an attempt to create music that can't be identified as being in "C Major" or any other key.
