Major and minor in September Guitar Chord Extensions
At their core, the major and minor chords are built from triads which consist root, third and fifth (1 3 5) intervals. These intervals are derived from the major scale and named according to their degree of scale. On other notes, or extensions, since the scale can be added to chords such as seconds, fourths, sixths and sevenths (2 4 6 7). Adding extensions creates more complex chords with richer sounds. This free guitar lesson will give you a quick introduction to this subject and how to apply this theory to music for the main fretboard and popular songs.
Major Scale Patterns and Chord Progressions
Before you begin to study extensions you should first learn to build major and minor chords (triads) from the major scale. It would including chord progressions and guitar playing by numbers (aka the "Nashville Number System"). You may even need to take a step back and see the scale models. Remember, each about music theory relies on the one before. Drawings major scale and construction agreements are two topics that are essential to understand and implement extensions of agreements.
Chord construction theory
If you've already gone through the process of construction agreements for the entire major scale, then you're ready to start adding extensions agreements. All you have to do is to repeat the whole process, but this time add an additional interval to the triad. For example, a seventh interval (or 7). Beginning on a note G in the key of G, 1 3 5 7 are GBDF #. The note F # is an interval of seven large and is just one note shy of an octave. Each time you add an F # to a G major chord you create a G major seven chord (or Gmaj7). This can be done with any form of agreements in G major at any position, and any F # note regardless of the octave. You have to rearrange your fingers to accommodate this extra note.
Then, add an interval of seven to rope II in the treble clef, A minor. To do this, count the notes of the G major scale STARTING ON A. If you do properly the seventh grade of A is close to G. This interval is called a flat seven because it's a box under seven major (or two boxes a shy octave). When you add a G note to a chord am creating a minor seven chords (or Am7). This can be done with any form of agreements Am in any position, and any G note regardless of the octave. You have to rearrange your fingers in order to take account of this extra note.
Now that you've identified the interval seventh for the first two chords in the key of G you can continue the process with the rest of the scale. If you do this correctly the following sequence must occur:
Harmonized Major Scale With sevenths
I Gmaj7
ii Am7
iii Bm7
IV Cmaj7
V D7 (which means "dominant" seven)
vi Em7
vii F # m7b5 (whoa, it's a mouthful!)
Dominant seven strings
The V chord, D7, is unique in that it is a major chord but it has an interval of seven courses as minor chords. Because of this, he has a particular name which is "dominant" seven years. For some strange reason, it is the agreement of the dominant seventh is written simply as "7." The major seventh chord should always include "major".
As with any subject of music theory you heard, you must apply for extensions to the key the guitar playing songs. The following lists will help you start naming some well known tunes that use seventh chords.

It is simply an introduction to adding intervals seventh string. Because So many ways to make minor and major chord shapes on the guitar fretboard, there are many ways to construct chords with sevenths too. In fact, the whole CAGED chord system may have seventh intervals added. Once you get a handle on the extension agreements with the seventh, you can try adding a few seconds, fourths and sixths. From there you can get into chords with multiple intervals added but do not get ahead of yourself. At least now you can begin to understand what the numbers next to the chord names are for! It is the beauty of the theory of learning guitar
