History of Slide Guitar

Slide guitar has deep roots that you can trace back to both the Mississippi Delta and Hawaii. In the late 1800s, African American musicians in the Mississippi Delta developed their own distinctive style, creating the bluesy sound that’s associated with the slide guitar. They typically used whatever was at hand for a slide, like a knife or a bottleneck, which refers to the neck of a glass bottle.

Interestingly, around the same time, Hawaiian musicians, separated by thousands of miles, were developing a similar technique. In Hawaii, Joseph Kekuku is often credited with inventing the Hawaiian slide guitar. Hawaiian slide guitar was introduced to the mainland U.S. during the late 19th and early 20th centuries, particularly through live performances and tours.

• Key Influences and Instruments:
  • Africa: The roots of the slide guitar can be linked to African musical traditions.
  • Mississippi Delta: The style was heavily shaped by the blues musicians of this region, with the Delta blues style characterizing the early slide sound.
  • Hawaii: Joseph Kekuku played a significant role in the development of the Hawaiian slide guitar.
  • Instruments: Besides the guitar, related instruments like the diddley bow and dobro also used slide techniques.

Early slide guitar recordings from blues artists like Sylvester Weaver in 1923 brought the style to a wider audience. Over time, artists like Robert Johnson, Elmore James, and Blind Willie Johnson were instrumental in further popularizing and refining the style.

Notable Artists:

• Robert Johnson: Known for his haunting and emotive playing style.
• Elmore James: Created a distinctive, electrified slide sound.
• Blind Willie Johnson: Combined slide guitar with gospel music.

These musicians laid the foundation for how you hear and play slide guitar across various genres today.

Fundamentals of Slide Guitar

In this section, you’ll learn the core elements of playing slide guitar, from understanding its unique approach to choosing the right materials that best suit your sound.

Slide Guitar Basics

Slide guitar involves a distinct method where you’ll use a guitar slide—a solid, smooth cylinder—over the strings rather than pressing them against the fretboard. This creates a continuous, fluid sound with a gliding pitch and prolonged sustain. To start, place the slide on your ring or pinky finger of your fretting hand. This allows your other fingers to remain free for conventional fretting. Ensure the slide is parallel to the frets and lightly touch the strings; pressure is key here. Too much and you’ll dampen the sustain; too little and the tone may be faint.

Choosing a Slide

When selecting a slide, consider the size and fit for your finger. It should be snug but comfortable—neither too tight to restrict movement nor too loose that it might fall off. While any finger can be used, many players prefer the ring or pinky for intuitive control.

• Ring Finger: More control, heavier slides possible.
• Pinky Finger: Easier chord playing with other fingers, good for lighter slides.

Slide Material and Tone

The material of the slide has a significant impact on the tone produced. Each one brings a characteristic sound:

1. Glass Slide: Produces a warm, smooth tone with less sustain.
2. Brass Slide: Louder and brasher, a brass slide offers a bright tone with more sustain.
3. Ceramic Slide: Yields a rich, full tone, blending warmth and clarity.
4. Steel Bar: Used mainly for lap steel or pedal steel guitar, it gives a sharp, pronounced sound ideal for country and Hawaiian music.
5. Bottleneck Slide: Often made from the neck of a bottle, its thickness provides a sustainful and bluesy tone.

Experiment with different materials to find the one that produces the sound you’re looking for. Remember, your playing technique will also affect sustain and tone, so practice is essential to master the nuances of slide guitar.

Playing Techniques

Mastering slide guitar requires a delicate balance of pressure and control. The following techniques are essential for crisp, soulful playing and effective sound management.

Holding the Slide

Choose your slide based on comfort and the sound you prefer. It can be made from glass, metal, or ceramic. Wear the slide on your ring or little finger for the most control; this allows your other fingers to unfretted strings or fingerpick. Ensure it’s snug but not too tight.

Slide Placement

Your slide should float just above the fretboard, making slight contact with the strings. Avoid pressing down too hard; excessive pressure can create unwanted noise and hinder smooth movement along the strings:

• Correct Placement: Directly over the fret, not in between.
• Vibrato: To achieve vibrato, move the slide slightly back and forth over the fret while maintaining light pressure.

Muting Techniques

Muting is crucial in slide guitar to prevent unwanted overtones and string noise. You’ll use both hands for this:

• Picking Hand: Use your palm or the side of your thumb to mute the strings behind the slide.
• Fretting Hand: Let your remaining fingers lightly rest on the strings behind the slide—this is known as left-hand muting.

Implementing these specific techniques will increase your finesse and overall control while playing slide guitar.

Tuning and Setup

When you’re diving into slide guitar, the tuning and setup of your guitar are crucial for getting that sweet, bluesy sound. Properly adjusted action and intonation, along with the right choice of open tuning, will set the foundation for your slide playing.

Open Tunings

Open tunings are essential for slide guitar because they allow you to play full chords by strumming the open strings. Here are three common open tunings you might try:

• Open G Tuning (DGDGBD): This tuning lowers the sixth, fifth, and first strings down a whole step, giving you a G major chord when strumming the open strings. It’s a versatile option often used in Delta blues and rock.
• Open D Tuning (DADF#AD): By tuning the strings to form a D major chord when played open, Open D provides a rich, resonant sound that’s great for a wide range of styles.
• Open E Tuning (EBEG#BE): Open E is similar in structure to Open D but tuned a whole step higher. Some players prefer it for its slightly brighter tone.

Action and Intonation

To play slide guitar effectively, you’ll need to adjust your guitar’s action and intonation:

• Action: For smoother sliding and to avoid fret buzz, raise your action slightly higher than normal. The strings need enough clearance so they don’t make contact with the frets when you slide. You’re looking for a balance where the action is high enough for clean slides but low enough for finger fretting if needed. String Regular Action Slide Action E (6th) Low Medium A (5th) Low Medium D (4th) Low Medium G (3rd) Low Medium B (2nd) Low Medium E (1st) Low Medium
• Intonation: Correct intonation ensures that your guitar is in tune with itself up and down the fretboard. For slide playing, it’s especially important to have accurate intonation since you’re playing over the frets and not pressing down. Poor intonation may become more noticeable when using a slide. Fine-tune each string until the open note and the note at the 12th fret harmonic match perfectly.

Slide Guitar Styles

When you explore the realm of slide guitar, you’re diving into a rich tapestry of musical traditions. Each style showcases distinctive techniques and tunings, offering you a unique avenue of expression on the guitar.

Delta Blues

In the Delta Blues style, slide guitar is characterized by emotive vibratos and slide techniques that mimic the human voice. You’ll find this style deeply rooted in the music of blues legends like Robert Johnson, who originally conjured its haunting sound. Tunings like open D and open G are your go-to choices, facilitating that classic wailing blues sound that captured Duane Allman’s and Bonnie Raitt’s performances. When you play Delta Blues, use a glass or metal slide to fret notes for that authentic raw and expressive tone.

Hawaiian Style

Moving to the Hawaiian Style, you’re looking at a mellower, smoother sound that evokes the islands’ serene vibes. This approach often employs slack-key tunings, where the strings are tuned lower than standard, giving a loose, relaxed sound. Open tunings are prevalent here, just like in Delta Blues, but with more emphasis on major keys. Pioneers of this style like Joseph Kekuku are credited with popularizing the slide guitar, which then influenced musicians in other genres, including rock and country.

Rock and Roll

When slide guitar entered the landscape of Rock and Roll, it brought with it a gritty and forceful tonality. Artists like Joe Walsh, Ry Cooder, and bands such as The Rolling Stones and The Allman Brothers infused slide guitar into rock, creating iconic sounds. While Eric Clapton played with slide techniques in a more blues-influenced rock context, Duane Allman showcased how slide guitar could be as complex and vocal as lead lines in a rock song. Listen closely to tracks like “Statesboro Blues” or “Can’t You Hear Me Knocking” where the slide guitar riffs and solos are as much the signature of the song as the lyrics.

Advanced Slide Guitar Concepts

When you’re looking to elevate your slide guitar skills, mastering advanced techniques is crucial for nuanced playing. These concepts will help you diversify your sound and add depth to your music.

Fretting Techniques

Your fretting hand plays a significant role in controlling pitch and adding expressiveness to your slide guitar play. Unlike standard fretting, where you press the strings to the fretboard, slide guitar requires you to hover the slide directly over the frets without pressing down.

• Vibrato: By oscillating the slide slightly above the fret you’re targeting, you create vibrato. The closer to the fret you stay, the more controlled the pitch will be.
• Chords: To play chords, angle your slide to cover several strings simultaneously, ensuring it is parallel to the frets for clarity.

Combining Slide with Standard Playing

You can add texture to your music by mixing slide techniques with conventional fretting.

• Fretting Hand Comfort: For ease in transitioning between slide and standard playing, keep the slide on your ring or pinky finger. This allows your other fingers to access the fretboard freely.
• Gain Settings: Manage the gain on your amplifier or pedal to maintain a balance between clean and driven tones, enhancing the distinctiveness of the slide against standard notes.

Personalization and Expression

Slide guitar playing is not just about technique; it’s a form of personal expression that allows you to add your unique touch to music. By developing your own style and embracing improvisation, you create a signature sound that can set you apart.

Developing Your Own Style

Your journey in slide guitar playing starts with understanding the basics, but quickly moves to developing a style that’s all yours. Duane Allman and Derek Trucks are prime examples of artists who crafted distinctive sounds that are immediately recognizable. Here’s how you can start:

1. Personal Preference: Begin by identifying the slide materials and guitar setups that feel comfortable and sound right to you. From glass to metal slides, each offers a different tone.
2. Different Tone: Experiment with various tunings and strings to find the tone that resonates with your musical taste. Thicker strings may be more challenging to play, but they produce a richer, fuller sound, often preferred in slide guitar.

By exploring these aspects, you’ll discover a style that aligns with your personal preference and sets the stage for your unique expression.

Improvisation and Emotional Expression

The heart of slide guitar is the ability to convey emotion through your instrument. Improvisation is the key to unlocking this emotional connection; it allows you to translate feelings into sound spontaneously.

• Feel the Music: As you play, focus on the emotional content of the song. Let your feelings guide the dynamics and intensity of your playing.
• Style Emulation: Listen and attempt to emulate the styles of slide guitar masters like Duane Allman and Derek Trucks. Notice how they incorporate their personality into their playing, then blend these influences with your creative voice.

Improvisation isn’t just about playing random notes; it’s a thoughtful process where you make purposeful musical decisions in real-time, adding depth to your playing style.
