Guitar Extended Chords

extended chords. Extended chords will add a whole new dimension to your playing. As beautiful as they sound they constructed and used according to certain rules. Some extended chords are named by the intervals contained in the chord. For example we use our key of C and C extended chords. For starters the C maj Triad consist of 1 3 5 tones or C E G, of the C Maj scale.

Our first extended chord to use is the C Major 7th. To produce a Major 7th chord we add a Major 3rd above upper note of the C triad G, which yields B. Resulting in;

1 3 5 7, C E G B.

To produce a minor 7th chord we add a minor 3rd above upper note of the triad G, which yields Bb. And also we lower the 3rd degree tone E to Eb. Resulting in:

1 3b 5 7b, C Eb G Bb.

To produce a Dominant 7th chord we add a minor 3rd above upper note of the triad G, which yields Bb. Resulting in; 1 3 5 7b C E G Bb. The next extended chord to use is the C Half-Diminished 7th.

To produce a Half-Diminished 7th chord we lower the 3rd, the 5th, and add a minor 3rd interval above upper note of the triad Gb, which yields Bb. Resulting in;

1 3b 5b 7b,

C Eb Gb Bb. Guitar Extended Chords
