How to Play an 8-Bar Blues on the Guitar

Starting with an 8-bar blues on the guitar can be a rewarding way to explore the blues genre. It’s shorter than the more common 12-bar blues, making it a great choice for beginners or those looking to try something new. This article will take you through the essentials of playing an 8-bar blues, from understanding its structure to adding your own personal flair.

Getting to Know the 8-Bar Blues Structure

Before we grab our guitars, it's helpful to get a sense of what makes the 8-bar blues tick. Unlike the 12-bar format, which is more prevalent in blues music, the 8-bar blues is like its succinct cousin. It tends to have a more straightforward and repetitive structure, which can make it easier to remember. The typical chord progression for an 8-bar blues can look something like this:

• Bar 1: I chord
• Bar 2: IV chord
• Bar 3: I chord
• Bar 4: I chord
• Bar 5: V chord
• Bar 6: IV chord
• Bar 7: I chord
• Bar 8: V chord (or I chord for a turnaround)

In the key of C, for instance, this would translate to C, F, C, C, G, F, C, G. Notice how the progression tends to resolve back to the I chord, giving it that familiar bluesy feel.

Getting Your Fingers Ready: Chord Shapes and Transitions

Now that we have the structure, it's time to talk about the chords themselves. The beauty of blues lies in its simplicity and the opportunity it gives for expression through subtle variations and embellishments. If you’re just starting, focus on mastering these basic chord shapes:

• C Major: Place your ring finger on the 3rd fret of the 5th string, middle finger on the 2nd fret of the 4th string, and index finger on the 1st fret of the 2nd string.
• F Major: Use the barre chord shape. Barre all strings at the 1st fret with your index finger, then place your ring and pinky fingers on the 3rd fret of the 5th and 4th strings, respectively, and your middle finger on the 2nd fret of the 3rd string.
• G Major: Place your middle finger on the 3rd fret of the 6th string, index finger on the 2nd fret of the 5th string, and ring finger on the 3rd fret of the 1st string.

Practice transitioning smoothly between these chords. Start slowly, ensuring each note rings clearly, and gradually increase the tempo as you gain confidence. If barre chords are tough at first, consider using partial chords or power chords, especially if you're coming from a metal background where power chords are more prevalent. Riffhard offers some fantastic resources that can help you nail these transitions, taught by some of the best metal guitarists around.

Adding Rhythm to Your Blues

Rhythm is the backbone of blues music. It's what makes the genre feel so alive and human. When playing an 8-bar blues, you can use a shuffle rhythm to add swing to your playing. This involves playing the first note of a pair longer than the second, creating a "long-short" feel.

An example of a basic shuffle rhythm in 4/4 time would be:

• 1 (long) - and (short) - 2 (long) - and (short) - 3 (long) - and (short) - 4 (long) - and (short)

Try applying this rhythm to your chord progression. Start with a downstroke on the longer beats and a lighter upstroke on the shorter beats. As you get more comfortable, experiment with adding accents or variations to make the rhythm your own.

The Role of the Dominant 7th Chord

One of the defining features of blues music is the use of dominant 7th chords. These chords add a bit of tension and character to your playing. To add these to your 8-bar blues, you can modify your chord shapes as follows:

• C7: Take your C major chord and add your pinky to the 3rd fret of the 3rd string.
• F7: From your F major barre chord, lift your pinky off the 4th string to let the 1st fret ring out.
• G7: From your G major chord, add your index finger to the 1st fret of the 1st string.

These chords will give your blues a more authentic and soulful sound, introducing a slight dissonance that resolves beautifully as you move through the progression. The use of dominant 7ths can also make you feel like you’re playing with the big blues bands, even if you're just jamming by yourself.

Exploring the Blues Scale

The blues scale is a cornerstone of soloing and improvisation in blues guitar. It’s essentially a pentatonic scale with an added flat fifth, sometimes referred to as the "blue note." Here’s a quick look at the C blues scale:

• C - Eb - F - Gb - G - Bb - C

Practice playing this scale up and down the fretboard. Try starting with the root note on the 8th fret of the 6th string. Once you're comfortable, begin experimenting with bends, slides, and vibrato to add expression to each note. The beauty of the blues scale is its simplicity—it’s easy to learn but offers endless possibilities for creative expression.

Integrating Licks and Riffs

Blues licks and riffs are short, memorable musical phrases that you can weave into your playing to add flair and personality. Here’s a simple blues lick you can try out in the key of C:

e|-------------------------
B|------8-10-8------------
G|--9b----------9-8-------
D|-------------------10---
A|------------------------
E|------------------------

Start slowly, focusing on the bends and making sure each note is clear. As you get comfortable, try incorporating this lick into your 8-bar blues progression. You can play it between chord changes or use it to begin or end your solo sections. Feel free to tweak it to suit your style—add slides, hammer-ons, or pull-offs to make it your own.

Improvisation: Making It Your Own

One of the joys of playing blues is the freedom it gives you to improvise. Once you have the basic structure and chord changes down, try improvising over the progression using the blues scale and any licks you’ve learned. Don't worry about making mistakes; improvisation is about experimenting and finding your voice on the guitar.

Start by playing along with a backing track or a metronome, which can help you keep time and stay anchored to the progression. As you experiment, listen to how your notes interact with the chords. Try playing a phrase, then repeating it with slight variations. This call-and-response technique adds depth and interest to your improvisation.

Bringing Dynamics and Expression

Blues is not just about the notes you play but how you play them. Dynamics and expression breathe life into your music, allowing you to communicate emotion through your instrument. Here are some techniques to try:

• Bending: Bend notes to add tension and release.
• Vibrato: Use subtle or wide vibrato to give notes a singing quality.
• Slides: Slide into or out of notes to create smooth transitions.
• Hammer-ons and pull-offs: Use these to add fluidity and speed to your playing.

Pay attention to the dynamics of your picking hand as well. Varying your picking attack—playing some notes louder or softer—can add contrast and interest to your performance. Blues is all about feeling, so let your emotions guide your playing.

Final Thoughts
