Heinrich Schenker was a total asshole who lived in Austria. Since he was pissed off at being a music theorist that no one cared about (because music theorists are lame), he decided to invent his own method of analyzing music which is really stupid and only appeals to other music theory dorks who want to appear intelligent and who need to find a way to somehow make money off of that DMA they worked so hard to get.
His legacy carries on to this day, where poor music students are forced to learn his analytical method by cruel music theory teachers, only to promptly forget about it after the final assignment is done because NO ONE IN THE REAL WORLD CARES.
Schenker was known for being extremely dogmatic about his own make believe system, and any piece that didn't fit it was considered poorly constructed (how convenient). This included some works by Brahms, a composer whose awesomeness could have made Schenker's stupid head explode into a million pieces.
When I began typing Heinrich Schenker's name into Google, it thought that I was asking about Heinrich Himmler. COINCIDENCE?!?!!
Seriously though. Fuck this guy.
Theory Dork: Hey, do you know about Heinrich Schenker?
Normal Musician: No I don't.
Theory Dork: Oh, he was great. He came up with this method for analyzing music that involves stripping all of the interesting stuff out of it and just reducing it to tonic and dominant chords.
Normal Musician: That sounds pretty stupid, retarded, idiotic and lame. Why would you do that?
Theory Dork: I had to write my dissertation about something. *cries*
