Welcome to Sheffield Guitar Studio! This week, we’re diving into the world of the 12-bar blues. This timeless chord progression is a cornerstone of numerous music styles, including blues, rock, jazz, soul, funk, and rockabilly. Today, we’ll explore what the 12-bar blues is, how to learn it, and ways to incorporate it into your playing.
What is the 12-Bar Blues?
The 12-bar blues is a simple yet versatile chord progression built around three primary chords. These chords, commonly referred to as chords I, IV, and V, form the backbone of the progression. For today’s example, let’s use the key of A, which gives us the chords A7, D7, and E7. By adding dominant sevenths and other notes, you can create a richer harmonic texture while retaining the structure of the 12-bar pattern.
The Basic Structure
The 12-bar blues progression typically follows this format:
1. Four bars of chord I (A7 in our example)
2. Two bars of chord IV (D7)
3. Two bars of chord I (A7)
4. One bar of chord V (E7)
5. One bar of chord IV (D7)
6. Two bars of chord I (A7)
This sequence creates a repeating 12-bar loop that forms the foundation for improvisation and variation. While this is the standard structure, it’s not set in stone. Many artists incorporate substitutions and alterations to make the progression unique.
Adding Variations
Variations breathe life into the 12-bar blues. Here are a few ideas:
- Chord Substitutions: Replace the second bar of A7 with D7 for a subtle twist.
- Alternative Endings: In bar 10, substitute the V chord (E7) with the IV chord (D7) to create a descending motion.
- Turnarounds: Use chord V (E7) in the final bar to resolve back to chord I (A7), enhancing the loop’s continuity.
These small changes add flavor and keep the progression dynamic and engaging.
Exploring Artistic Interpretations
The 12-bar blues isn’t confined to its basic form. Iconic artists like John Lee Hooker have creatively adapted the progression, sometimes extending or shortening bars to suit their unique style. Jazz musicians, on the other hand, often incorporate complex chords and substitutions to elevate the harmony. The best way to deepen your understanding is by listening to a variety of blues and jazz recordings.
Practical Tips for Mastery
1. Start Simple: Stick to the basic chords and structure until you’re comfortable.
2. Experiment: Try out substitutions and variations to personalize the progression.
3. Improvise: Use the 12-bar blues as a foundation for soloing and improvisation.
4. Listen and Learn: Study recordings by great blues artists to understand different interpretations.
