So i've been trying to figure this out for a while and still can't seem to so hopefully someone here can help me tongue.gif
I've been trying to understand something i read which says" if you build a triad from each note of the G major scale you'll get the following diatonic chords G,Am,Bm,C,D,Em and F#dim"

so my main question was understanding how do you know if the triad/arpeggio will be minor or not because i know that in the G major scale the notes are g,a,b,c,d,e,f#... so lets say you're playing those arpeggios diatonicly down the neck how would you know which ones to make minor as in the A would be minor according to what i read and the f# would be diminished... how do you figure that out?? HELP! ohmy.gif

A triad is 1,3,5 so whichever note you start on becomes 1 you then move up the scale to find 3 & 5 you will end up with the chord pattern within that scale. Eg A-C-E gives you Am and E-G-B gives you Em. Hope that helps.

A minor triad consists of the root, minor 3rd and (perfect) 5th, while a major triad has the major 3rd instead of the minor.

Building triads using 1 3 5 from a certain scale, using various notes as root notes, results sometimes in major triads and sometimes in minor triads. In some exceptional cases we get other options as well (such as the black sheep F#dim in your example).

Now, from the major scale, in this case G major - if we use the A as the root note, the other two notes in the triad are C - which is a minor 3rd from the A - and E - which is a 5th from the A; together they make a minor triad (because of the minor 3rd).

I hope this makes sense.

I've just started creating a big Triads lesson project for the Wiki.

1 - major
2 - minor
3 - minor
4 - major
5 - major
6 - minor
7 - diminished

In a major scale it'll always follow the pattern, if that's what you're looking for?

Wait until you start superimposing triads on top of the existing harmony in order to get all the upper structure tensions!

Then on to triad pairs and hexatonic scales!!!

Triads are where it is at..... You can really spice up your playing by learning to use them to compliment scales and arps.

I'm eventually going to film some lessons on these topics.

I'm creating it as I wanted some core fundamental things to practice and drill into my brain, fingers and ears, when I feel uninspired, but want to use my time well.
So this isn't something I'm a master of, rather something I know I need to master.

I'm using Neck Diagrams to create lots of useful visual aids.

Topics I'm thinking of so far are

What are triads and how to build them from the diatonic scales
Triads on String Sets 654, 543, 432, 321
Wide Voiced Triad Ideas (Eric Johnson, Neil Zaza)
Superimposing Triads


And Scott, yes I will be taking most of the ideas from all of Tomo's triad threads in TGP!

If we take the Chromatic scale (the entire 12 notes of western music)

C, C#/ Db, D, D#/Eb, E, F, F#/Gb, G, G#/Ab, A, A#/Bb, B, C

Each note is a Semitone or Half Tone away from the next (there is no E#/Fb or B#/Cb)

The Major Scale is created using the intervals T, T, H, T, T, T, H

So if we start with C
C, D, E, F, G, A , B, C
Start with G
G, A, B, C, D, E, F#, G


To get the triads we take the 1, 3, 5 intervals from each note of the major scale

1, 3, 5
C, E, G
D, F, A
E, G, B
F, A, C
G, B, D
A, C, E
B, D, F#

If you look at the 1 and 3 notes on the Chromatic Scale

C to E is 2 whole tones away so a 3rd interval
Whereas D to F is a whole half tone away, so we call that a flatted 3rd or MINOR 3rd

The 5th in these triads are all

This is what makes the difference with the major and minor triads

The diminished is weird because it has a flat 3rd interval and a flat 5th interval too

Crap I didn't edit that correct, Ignore the incomplete sentence about the 5th, it's just a 5th!

The easiest way to look at this - in my opinion - is to think of these arpeggios or chords as being made up ONLY of notes belonging to THAT scale you are in. In our case G major:

If we pick a random chord/ arpeggio, obtained by harmonizing the G major scale, we will get a chord being made up only of notes belonging to the G major scale. So for instance, the A chord will be minor because it is made up from the A C E notes which all belong to the G major scale. It could not have been a major chord, as we would need C# and C# DOES NOT belong to the G major scale.

Hope this one helps as well biggrin.gif

Just using the 1 3 5 triad method like everyone else in the thread has.

If you're asking WHY it's like that, then I dunno. It just is. (But, I think it has something to do with frequency ratios and pythagorus? Screw maths.)

ok so after reading all of this, it all makes sense now, just use the 1,3,5 formula on the next note of the scale you're working with following the notes of that scale.. smile.gif

Major - (I) Major, (II) Minor, (III) Minor, (IV) Major, (V) Major, (VI) Minor, (VII) Dim - (I) Major

Minor - (VI) Minor, (VII) Dim, (I) Major, (II) Minor, (III) Minor, (IV) Major, (V) Major - (VI) Minor.


Think it works like that. Your thinkin is correct but you skipped a degree.

If you want to use 7th chords, it goes like this:

Major - (I) Major 7th, (II) Minor 7th, (III) Minor 7th, (IV) Major 7th, (V) Dominant 7th, (VI) Minor 7th, (VII) Minor 7th Flat 5 - (I) Major 7th

Minor - (VI) Minor 7th, (VII) Minor 7th Flat 5, (I) Major 7th, (II) Minor 7th, (III) Minor 7th, (IV) Major 7th, (V) Dominant 7th - (VI) Minor 7th.
