According to my major key, tonic chorus theory, the first semi-final of Eurovision 2011 should have eliminated Albania, Turkey, Russia, Portugal and Serbia (non-tonic choruses).
The contest is in a rut of minor key choruses at the moment (the last five winners), so Poland, Georgia, Malta and Hungary (minor choruses, started on the tonic) should have been in with a chance. Greece had a chorus starting on the tonic minor, and with a big fat key change towards the end, so that’s good odds.
The countries that ought to have done even better, according to the theory, are Lithuania, Armenia, (minor key, but major key tonic chorus), Azerbaijan, Iceland, San Marino, Finland, Switzerland, and Norway (major key, major chorus starting on the tonic), with Croatia doing particularly well (major key, major chorus starting on the tonic and a big fat Eurokey change).
In reality, the eliminated countries were Poland, Norway, Albania, Armenia, Turkey, Malta, San Marino, Croatia and Portugal.
So my theory predicted three out of five eliminees purely on the basis of a non-tonic chorus. And I was really, really wrong about Croatia.
Of course, if one actually listens to the songs, and sees the performances, Serbia’s non-tonic chorus is overidden by its Bacharach-esque charm. It’ll do well.
Also, I think the songs are getting shorter (no data, just a hunch), and that makes the big Euro key change harder to pull off. A grand institution is under threat, folks.
Maybe the songs are all STARTING at the key change?
