I have a tutorial on modes in Scottish traditional music (though in fact applying to most folk music from Western Europe) which has grown to book-length over several years: http://www.campin.me.uk/Music/Modes.abc It's been getting very unwieldy to edit, so I've split it up into sections: http://www.campin.me.uk/Music/Modes/ Does anybody prefer it the old way, or can I phase that out? At present the content of both versions is the same.
