Chord Construction: Triads 2

This lesson will move quickly through the building of the other triads. The process is the same as for the major triads, the only difference is that the interval structures are different.

Minor Triad

The interval structure of this triad is a minor third above the root, and a perfect fifth above the root. Using interval shapes and starting on the 6th string, 5th fret, we would come up with this:

E---------
B---------
G---------
D----2----
A----3----
E----5----

Notice that this produces the note names A C E, which is correct, becaus they are the note names of a minor triad starting on A. The following is the shapes of minor triads that cross the 2nd and 3rd strings(when the root is on the 4th string, and when the root is on the 3rd string):

E-------3-
B----3--4-
G----3--5-
D----5----
A---------
E---------

Notice how the interval shapes change to accomodate the different tunings between the 2nd and 3rd strings.

The following examples will state the interval structure of the triad, and then give an example of that type of triad, which the root on the 1st, 4th and 3rd strings.

Diminished Triad

The interval structure is a minor third above the root, and a diminished 5th above the root. With a root of A, the spelling will be A C Eb.

E-------2-
B----2--4-
G----3--5-
D-1--5----
A-3-------
E-5-------

Augmented Triad

The interval structure is a major third above the root, and an augmented 5th above the root. With a root of A, the spelling will be A C# E#.

E-------4-
B----4--5-
G----4--5-
D-3--5----
A-4-------
E-5-------

These are all the triads. Now you are able to play any triad, starting on any note, with the root on any string. Not bad, eh? Now that you've built these triads, try to learn some of as complete shapes of their own. This will help in the next lessons that will deal with the building of bigger or more complex chords.

Things to remember from this lesson:

1. You can now build any triad, starting on any note, with the root anywhere on the neck. Don't forget to remember the note names when using these shapes.
2. Memorizing some of these shapes will help you with the construction of bigger or more complex chords, which will be looked at in the next lessons.
