Ep0. Why and How should (the history of) jazz be studied in Philosophy of Jazz?
Why the History of Jazz is Important to Philosophy of Jazz
Although the question's answer may seem obvious that the history of jazz would be studied in the philosophy of jazz, it nevertheless behooves philosophers of jazz to justify and explain jazz's history as relevant for doing philosophy of jazz.
What reasons and arguments explain and justify the relevance of the history of jazz for doing philosophy of jazz?
For example, if jazz's history had been different how would this affect the philosophy of jazz?
Although at first it might seem likely me a trivial pseudo problem it quickly turns into a genuine problem. The pseudo answer is from Earth's perspective what twin Earthlings call rock ' n roll is what Earth calls jazz.
But, how is thus known. In the original description it was stated as a fact that Twin Earth rock was really Earth like jazz. But this us cheating. You can't just specify it. Of course, because in the thought experience have specified that the two Earth's have identical histories up to a point, but if they diverge at some point so as to have different features, then it is no longer certain that just because two songs are both called "Honeysuckle Rose" it certainly doesn't follow they are the same song.
How could one tell the Earth version and the Twin Earth version are or are not the same song?
There will be many different answers to this question depending upon your theory of song or musical work identity.
- Sonicism and Nelson Goodman's Perfection Requirement for musical work/song identity both require note for note identical scores. Julian Dodd's sonicism even requires performance identity note for note to count two performances as being of the same song.
- Common sense would begin by saying to listen to the two songs and hear if they sound alike. But here a problem raises its head. No two performances ever sound exactly alike so clarification is needed for what has to be alike in the two performances and how they are alike and justify why these are the relevant factors for determine song or musical work identity.
But we all know common sense can often be wrong. Common sense does not think the Earth is spherical or that there could be a limit to how fast things can be accelerated. Common sense doesn't recognize the limitations that Einstein's theory of relativity forces upon accelerating masses.
For an example of a pseudo problem turning into a real problem, imagine that on Twin Earth they switched labels and what on Twin Earth is called jazz is what on Earth is called rock 'n roll and vice-versa.
How would they determine that this switch of labels is accurate so that Earth's rock is call on Twin Earth jazz?
