We recently established a successful Useful Concepts Repository. It got me thinking about all the useless or actively harmful concepts I had carried around for in some cases most of my life before seeing them for what they were. Then it occurred to me that I probably still have some poisonous concepts lurking in my mind, and I thought creating this thread might be one way to discover what they are.
I'll start us off with one simple example: The Bohr model of the atom as it is taught in school is a dangerous thing to keep in your head for too long. I graduated from high school believing that it was basically a correct physical representation of atoms. (And I went to a *good* high school.) Some may say that the Bohr model serves a useful role as a lie-to-children to bridge understanding to the true physics, but if so, why do so many adults still think atoms look like concentric circular orbits of electrons around a nucleus?
There's one hallmark of truly bad concepts: they actively work against correct induction. Thinking in terms of the Bohr model actively prevents you from understanding molecular bonding and, really, everything about how an atom can serve as a functional piece of a real thing like a protein or a diamond.
Bad concepts don't have to be scientific. Religion is held to be a pretty harmful concept around here. There are certain political theories which might qualify, except I expect that one man's harmful political concept is another man's core value system, so as usual we should probably stay away from politics. But I welcome input as fuzzy as common folk advice you receive that turned out to be really costly.
I don't share this impression at all. How much piano music do you know? There's probably a lot more of it than there is of organ music. This is certainly the case in the nineteenth century, which was probably the heyday of the diminished seventh (while being the low point of the organ repertory).
Eh? Among a combined total of 70-80 examples on this page and this one, I count about 7-8 Baroque examples, so about 10%. I'm not going to count through all the other 24 pages for comparison, but I don't think this supports the thesis that the diminished seventh is particularly characteristic of the Baroque as opposed to the Classical or Romantic; indeed, it is the Romantic which dominates the examples, as I predicted above. (And note by the way that not one of the Baroque examples that I could find was specifically an organ piece!)
What data is this based on? And for what definition of "weird"? Did you see the Mozart example I cited in my other comment? Do you have any reason to think that example is particularly uncharacteristic (in a way that your Bach example isn't)?
This a piece with plenty of diminished sevenths! (And what do you mean by "juxtaposed in unusual ways"?)
Phil, in all seriousness, you really ought to look at the Westergaard book. You would like it, and it would really help clarify your thinking about music. (I believe I have already directed you to an electronic copy via e-mail.)
