Chord formations

OK, so I know my basic 5 scales. Major, Minor Pentatonic, Blues Scale, Major Pentatonic and Minor. I've been reading through some of the thread on the MB and I now know about chord formations in the major scale: Maj, Min, Min, Maj, Maj, Min, Dim. Does anybody know what the chord formations are in the other scales or is there a logical way to work them out. Also, when your trying to learn a song by ear, what do you listen for. Is it the first chord, for example G, to tell you what key your in, are you listening for the scale and how do you identify what scale your in if the key is G. Can anybody help?

Well If your in the Key of G any G major Scales will work. As will most scales with the note G. You also have relative scales. In G major the relative minor would be I believe Em. To find the relative minor just go three frets down from the root note in the major scale. Theory isn't really my strong point but I know enough to get by.

The above is absolutely right - but I'm a little confused about you question "Does anybody know what the chord formations are in the other scales or is there a logical way to work them out." The chord formations stay pretty much the same in any key, in that a minor key chord structure is much the same as the major. If you understand how a minor key is formed it's just a matter of placing the relevant chords in the I, II, III, IV, etc. positions.

For example, in Dm the notes go "D, E, F, G, A, Bb, C", where the I, III, and V are minors, but the rest are either Major's or Dominant chords...The same princible can be applied to most other scales, although there is a little more theory behind them - perhaps you should check out some of the lessons on GT to get a better understanding?...

Don`t assume that those are the only chords you can get from the major scale.
If you harmonize the scale with triads, then, yes you get the chords you mentioned.
And if you harmonize the scale with seventh chords you get:
Maj7, Min7, Min7, Maj7, Dominant7, Min7, dim7.
And the logical way of building chords is taking a note and then stacking thirds above that note.

Em Scale=[ E,F#,G,A,B,C,D,E]
Let`s make a chord on the fourth note(A)
You are gonna need the "A" as the root and then go every other note.
[A,C,E] and this is an A minor chord.

Another example?
Let`s make a chord on the third note(G)
Take "G" and then stack intervals of third above it(every other note)
{G,B,D} or a G major chord.

There you go buddy, that is the most basic way of making chords.
