Blues Guitar Theory

Simplifying Blues Guitar Theory

Blues guitar is often shrouded in a lot of discussion and misunderstanding, but the theory behind it is relatively straightforward. Let's start by examining blues in the key of E. Many guitarists assume that the E minor pentatonic scale with a flattened fifth is the go-to scale for this key. Your primary chords would be E, A, and B, or I, IV, and V. However, most blues guitarists blend various scales when soloing.

The Mixolydian Scale

The Mixolydian scale is similar to the major scale but features a flattened seventh. The root note of the Mixolydian scale is the fifth note of the key you're playing in. For instance, if you're playing in the key of E, the Mixolydian scale starts at B.

To use the Mixolydian scale in blues improvisation, play the major scale a perfect fifth below the chord you're playing. For example, to use the Mixolydian over an A chord, play the D major scale but start with the note A.

Practical Application

It's more beneficial to approach blues through playing rather than theorizing. Once you can play a basic twelve-bar blues using the minor pentatonic scale, you should learn some turnarounds. The turnaround is the segment at the end of the twelve bars that sets you up for the next verse. Start by imitating what you hear on records. Even if your solos don't sound great initially, mastering a few turnarounds will significantly improve your playing.

The Importance of Listening

Listening is crucial when learning blues guitar. Spend at least half an hour listening to great blues guitarists as part of your practice routine. This will have a noticeable impact on your playing.

Improvisation Techniques

When learning improvisation, you can play single notes or chords. As a solo guitarist, you have the option to play an improvised solo over a chord progression or a single-note melody accompanied by bass notes on open strings. Playing a single-note tune with bass notes on one or two open strings helps train your ear and, with regular practice, allows you to guide the notes naturally.

The Role of Live Performance

Performing with other musicians in front of an audience can be intense and often diminishes the ability to listen and respond to the music being created by the singer, bass player, drummer, and rhythm guitarist. Developing this skill is essential for any improvising guitarist.

Conclusion

Blues guitar theory doesn't have to be daunting. By focusing on practical application, listening, and improvisation, you can master the basics and develop your unique style. Remember, the key to great blues playing is not just in the notes you play but in how you play them. Keep practicing, keep listening, and most importantly, keep playing.
