Intermediate Guitar Lesson 19

Dominant 7 Triads

By Brian Turner

Occasionally a chord such as the Dominant 7 and especially the Major 7 will have a 5 fret span. These chords present a challenge to finger. I recomend that beginners skip them for now and go to the next chord.

The Dominant 7 chord (C7) omitting the 5 and adding the b7.
The Dominant 7 actually has four notes: the 1st, 3rd, 5th, and b7. However, the 5th can be omitted leaving the 1st, 3rd, and b7th. The b7 interval is 1/2 tone (1 fret) higher in pitch than the 6th interval. In the exercise below the majoris shown first to illustrate how the 5th of each major triad is raised 1 1/2 tones (3 frets) to the b7 creating the Dominant 7.
