How to Build Dominant 7th Arpeggios
As you may have noticed, Dominant 7th chords are found everywhere in modern music. From blues to jazz to rock to country, you can see these chords all over the progressions of your favorite songs.
But, while we may recognize these chords, know some shapes to play them on the guitar, and maybe have checked out the Mixolydian Mode, often we forget about the chord tones themselves, the Dominant 7th Arpeggio.
This arpeggio is built one of two ways. The first is to take a major triad, as you can see below, and add a b7th on top of those 3 notes, the b7 is found 1 whole-step below the root of the chord you are on.
Here is how that looks like on paper.
As you can see, this means that any Dominant 7th Arpeggio is built with the intervals 1-3-5-b7 above the root of the chord that you are on.
The second way that you can build Dominant 7th Arpeggios is to look at the 1-3-5-b7 of the Mixolydian Mode.
You can see this here, where there is a C Mixolydian Mode in the first bar, and the first, 3rd, 5th and b7th notes of that scale have been taken out and pushed to the second bar, where they create a C7 Arpeggio.
