There are a number of things I encountered, including that one of course, that are really not good.fmr wrote: Wikipedia.
Regarding the "Modern" part of the article, I don't subscribe it, and I don't believe it was from the same author of the first part, but since the articles are not signed, I can't really say. However, the first paragraph pretty much sums all I consider wrong in the approach: "The modern Western modes consist of seven scales related to the familiar major and minor keys.". As has being pointed by me and others, the confusioncreated by realting modes with major and minor "keys" makes me believe it was written by someone with much lesser knowledge of music. Besides, it's not more "modern" than any other approach, namely those that create really modal music. It's a "particular" approach, made by a "particular" group.
This is a good example where Wikipedia can be helpful, but one need to be careful about what's in there.
Again, the relationship of ostensibly six other modes to major is just coincidental. 'Major' there is Ionian in the first place. Without sidetracking into where that came from and that history, Ionian is not Major per se.
Touching on the cross-influence of 'non-west' to 'west', in the 19th century 'Bilaval Thaat' arose in Hindustani conception of the raag. Same heptatonic scale as Ionian to a modern westerner. You'll see a raag posted at youtube 'Western mode'. But the raags do not show a particular embrace of 'leading tone to tonic'. The opposite, the ^7 is a plateau or subdominant typically, in fifth relationship to ^3 or third relationship to the P5. The prescribed 'vakra' or break in the line indicates something other than the tonic as its next move. It could really dwell on ^7 and feel quite rested there. It does not sound at all like 'Do, a deer...', or 'Somewhere Over the Rainbow'.
So 'Major' given as mode 1 is dodgy to begin with, it's a coincidence. Ionian is apparently a mode in its own right.
Major has connotations. Yes, we say 'major mode' vs 'minor mode' vis a vis common practice period music, but I don't like Major confounded with Ionian so completely.
So again, Dorian is the second mode of Ionian is the same statement as Ionian is the seventh mode of Dorian as far as it goes to a modern musician. IE., giving weight to one of them like it's the font where the others flowed from is just a mistake out of an incomplete education.
