What is the Steel Guitar?

The term steel guitar doesn’t refer to a specific brand or body shape, but rather to a family of guitars played using a steel bar or slide rather than by pressing the strings directly with the fingers. These instruments are known for producing a smooth, gliding sound often associated with country, Hawaiian, blues, and western swing music.

Unlike traditional acoustic or electric guitars that are typically played with fretting fingers pressing strings against the fretboard, a steel guitar is played horizontally, with the strings facing upward. The musician uses a steel bar (also called a tone bar or slide) to glide across the strings, creating continuous pitch changes that are difficult to achieve on conventional guitars.

Historical Origins of the Steel Guitar

The steel guitar’s origin story begins in Hawaii in the late 19th century. It is widely believed that the technique of playing with a steel bar originated with Joseph Kekuku, a Hawaiian teenager who, around 1889, discovered the unique sound produced when sliding a metal object along guitar strings.

Kekuku’s innovation quickly became popular in Hawaiian music, contributing to the distinct “slack key” guitar style. Hawaiian musicians began traveling the mainland United States and abroad, showcasing their music and steel guitar playing techniques, which captivated audiences and inspired the development of new instruments and styles.

By the early 20th century, the steel guitar had made its way into country and western music in the continental U.S., eventually evolving into multiple formats such as lap steel, pedal steel, and console steel guitars.

Basic Anatomy and Playing Technique

Steel guitars can look quite different from standard guitars, but they share several core components:

1. Body Configuration

Steel guitars come in both acoustic and electric forms. Lap steels often have a solid or hollow body similar to a guitar but are played while resting on the player’s lap or on a stand. Pedal steels typically have legs, pedals, and knee levers for controlling pitch changes, making them more complex.

2. Strings

Most steel guitars have six to ten strings, though some pedal steels may have up to twelve or more. The string spacing is wider than on standard guitars to accommodate the steel bar.

3. Tunings

Unlike the standard EADGBE tuning on a typical guitar, steel guitars use open tunings. Common tunings include C6, E9, and A6, depending on the music style and instrument type.

4. Steel Bar (Tone Bar)

The most defining feature is the steel bar or slide used to press against the strings. It is usually made of metal or glass and held in the non-picking hand.

5. Picking Technique

Steel guitar players often use fingerpicks and thumb picks for a crisp, articulate attack. Mastery of blocking techniques—such as palm blocking and pick blocking—is essential to clean playing.

Types of Steel Guitars

1. Lap Steel Guitar

The lap steel is one of the most accessible types of steel guitar. As the name implies, it is played on the musician’s lap or on a tabletop. It typically has six to eight strings and is tuned to an open chord.

Key Features:

  • No pedals or levers
  • Easy to transport
  • Used in Hawaiian, country, and blues music

2. Console Steel Guitar

A console steel guitar is similar to a lap steel but mounted on legs or a stand, allowing the player to stand or sit. It may have multiple necks, each with different tunings.

Key Features:

  • Heavier and less portable
  • Allows fast switching between tunings
  • Popular in western swing and jazz

3. Pedal Steel Guitar

The pedal steel guitar is the most advanced and versatile type. It includes foot pedals and knee levers that change the pitch of individual strings, enabling smooth chord modulations and intricate harmonies.

Key Features:

  • Complex mechanical system
  • Commonly uses E9 and C6 tunings
  • Essential in modern country music
  • Requires significant practice to master

4. Resonator Steel Guitars (Dobros)

Though not always classified as steel guitars, resonator guitars—especially those played lap-style with a slide—can be considered part of the steel guitar family.

Key Features:

  • Metal resonator cone for volume and tone
  • Often played with a slide
  • Used in bluegrass and blues

Steel Guitar Tunings and Their Importance

One of the most distinctive aspects of the steel guitar is its use of multiple tunings, each offering different chord voicings and melodic possibilities.

Common Tunings:

Open G (D-G-D-G-B-D) – Popular for blues and rock

Open D (D-A-D-F#-A-D) – Full, rich sound; good for slide

C6 (C-E-G-A-C-E) – Common in Western Swing

E9 (B-D-E-F#-G#-B-E-G#-D#-F#) – Standard for pedal steel in country music

Each tuning is tailored to different genres and player preferences. The choice of tuning significantly affects the player’s ability to form chords, harmonize melodies, and execute expressive bends.

Musical Genres and the Steel Guitar

Steel guitars have made a profound impact across a wide range of genres:

1. Hawaiian Music

The birthplace of the steel guitar, Hawaiian music features prominent use of the lap steel. Its smooth, melodic phrasing evokes the island’s relaxed and soulful ambiance.

2. Country and Western

Perhaps the most recognized use of the steel guitar today is in country music, especially through the pedal steel guitar. Its iconic bends and lush chords are signature sounds in artists like George Jones, Loretta Lynn, and Alan Jackson.

3. Western Swing

Artists like Bob Wills and His Texas Playboys brought the steel guitar to prominence in Western Swing, combining jazz elements with country.

4. Blues

In the Delta blues tradition, many slide guitarists adopted techniques similar to steel guitar playing. Though most blues slide players use standard guitars, resonators and lap steels are also common.

5. Rock and Americana

Rock artists like David Gilmour (Pink Floyd) and Jerry Garcia (Grateful Dead) have used lap and pedal steel guitars to add texture to their recordings. The steel guitar has also found a home in Americana, folk, and indie music, where it adds emotional depth and atmosphere.

Technique and Expression in Steel Guitar Playing

What truly sets the steel guitar apart is its potential for emotive expression. The glissando (sliding between notes), vibrato, and harmonic overtones create a soundscape rich in feeling and nuance.

Key Techniques:

Sliding: Smooth transitions between pitches

Bar slants: Angling the bar to play chords or harmonics

Palm blocking: Muting unwanted string noise

Harmonics (chimes): Lightly touching the string at nodes

Volume pedal swells: Adding dynamics for expressive phrasing

Mastering these techniques requires a blend of musical ear, dexterity, and fine control, especially with pedal steel guitars, where coordinating pedals, knee levers, bar, and picks simultaneously can be daunting.

Famous Steel Guitar Players

The steel guitar has been shaped and defined by numerous legendary musicians. Some of the most influential include:

Buddy Emmons – Known as the “Big E,” he revolutionized pedal steel playing with technical brilliance and jazz-infused style.

Speedy West – A pioneer in country and Western Swing steel playing.

David Lindley – Worked with Jackson Browne and others, blending lap steel into folk-rock.

Jerry Byrd – A Hawaiian steel master who taught generations of players.

Paul Franklin – One of Nashville’s top session pedal steel players, heard on countless hit records.

These artists pushed the boundaries of the instrument and brought the steel guitar to audiences worldwide.

Conclusion

The steel guitar is more than a novelty or a regional curiosity—it is a powerful musical tool with emotional depth and technical versatility. From its humble Hawaiian origins to its central role in country and Western music, the steel guitar has carved out a place in global music culture.

For players willing to embrace its unique approach, the steel guitar offers endless opportunities for creative expression. Whether used for mournful ballads, joyful swing tunes, or ambient soundscapes, the steel guitar continues to captivate audiences with its unmatched voice.
