Confusion w/ minor scales

[wise]

Initially I thought I understood how to form many of the chords for minor scales, but I'm somewhat confused now.

First check out the chart at bottom of this tutorial, from what I understand, these are all of the formable chord types based on any given scale...

But then now check out the chord chart on this page:

http://www.personal.psu.edu/users/f/p/fpm108/glw/lessons/lesson36.htm

Isn't the patter for all chords formed from scales Major, minor, minor, major, major, minor, diminished? Assuming that is correct, how does the chart from the second link have degree 1 containing a minor, degree 2 containing a diminished etc...? Shouldnt it be abiding by the major, minor, minor, major, major, minor, dim rule? Could someone please clear up this confusion with some examples? Thanks.

ok, I didn't check the thing you said, hehe, but...
you are right about the chords within the major scale being those chords. When it comes to modes or other scales, then its certainly not going to be the same. But as long as you know how to form chords, then it will be easy. Go get a pen and paper. To make a chord within the scale start with any note on the scale (write it down) skip one and write the next down, skip one and write the next down. The intervals between each notes will be 3rds, but depending on whether theyr are minor or major makes the chord.
2 minor thirds means a diminished chord. 1st minor 3rd then major third means a minor chord. 1st major third then minor third means a major chord. 2 major thirds means an augmented chord.
That pattern will give you the basic major, minor, dim, aug chords

My lord, that was an entire chunk of theory I overstepped. Glad someone got me confused, made me review a bit.

Ok, the topic relates to Diatonic Triads. Now I finally understand.

So now I see why each of these are as they are:
Major: maj, min, min, maj, maj, min, dim
Natural Minor: min, dim, maj, min, min, maj, maj
Harmonic Minor: min, dim, aug, min, maj, maj, dim
Melodic Minor: min, min, aug, maj, maj, dim, dim

So that leads me now to finally realize that each mode has their own entire pattern...So I have an interesting question then related to chord progressions.

Some of these scales won't be able to follow the generic I, IV, V or II, III, VI progression patterns such as the Harmonic and Melodic Minor Scales. The Natural Minor and Major scales seem to work great for those progressions, but correct me if I am wrong, if you wanted to have a nice progression for say the Harmonic, you'd have to make up your own such as V, VI for a 2 chord major progression which just wouldnt sound good in a normal Major Scale. All comments are welcomed.

Well if you're going for mere opinions, then... what I seem to hear from alot of musicians now adays is they want to break out of the rules, and try and make music their own. So I think the thought on HAVING to come up with a generic chord progression for modes is null. People will do it, there is probably already a generic prog for all the modes, but as a whole after hundreds of years, people are looking to break out of it all.

And if that wasn't what you wanted... then stiff bikkies, coz I cbf writing heaps of other stuff, lol =]
