Elevate Yoru Blues Solos: The Art of Dominant 7 Arpeggios
To break free from the conventional sound of blues solos that frequently enough rely on pentatonic scales, consider weaving dominant 7 arpeggios into your improvisational lines. As the term suggests, a dominant 7 arpeggio is created by playing the individual notes of a dominant 7 chord, such as G7, C7, or D7, in succession.
Understanding the G7 Chord
Let’s take the key of G as our reference point. In Figure 1, you’ll find a G7 chord illustrated in the 3rd position, followed by the G minor pentatonic scale (G, Bb, C, D, F) played in the same position.
To craft more captivating solo lines, I often blend the notes from the minor pentatonic scale with those from a dominant 7 arpeggio. Notably, these two share three common notes: the root, the 5th, and the minor or “flat” 7th.
Exploring the G7 Arpeggio
Figure 2 depicts a G7 arpeggio constructed from the notes G, B, D, and F. The first three notes form a G major triad, while F serves as the minor or “flatted” 7th, giving it that distinctive dominant 7 sound. Figure 3 illustrates these notes played in a descending pattern across the lower strings.
Incorporating Articulation Techniques
Utilizing articulation techniques such as finger slides and string bends can effectively integrate the dominant 7 pitches into your phrases. As a notable example,Figure 4 starts with a series of slides into the notes G,B,D,and F,each approached from a half step below,concluding the phrase with customary blues lines based on the G blues scale (G,Bb,C,Db,D,F).
Practicing with Rhythm Loops
A productive way to practice improvising with dominant 7 arpeggios is to loop a rhythm section and solo over it.Figure 5 presents a straightforward shuffle rhythm that revolves around a G7 chord.
Figure 6 demonstrates the notes of a G7 arpeggio played over the loop, first in an ascending pattern and than descending.This approach frequently enough evokes a “jazzy” feel, as it emphasizes chord tones, a common practice in jazz. The inclusion of B, the major 3rd, alongside F, the minor or “flatted” 7th, strengthens the connection to the G7 chord’s harmony.
Combining scales and Arpeggios
Figure 7 provides a more extended example of how to merge phrases derived from the G minor pentatonic and G blues scales with G7 arpeggio shapes. The first two bars focus on the G blues scale, followed by bars 3 and 4, which highlight the major 3rd, B, thus introducing the dominant 7 arpeggio sound.
In bars 5-8, I alternate between straightforward G minor pentatonic and blues scale phrases while incorporating the major 3rd, B, to bring the arpeggio sound back into focus. Throughout the remainder of the example, I fluidly transition between these two methods, aiming for musicality in how the different elements interact.
As you explore this dual approach, think of it as a continuous exchange between scales and arpeggios. Trust your ears to recognize the distinct musical effects produced and let them guide your note selections.
