Hawaiian Guitar Vs Acoustic Guitar: What’s The Actual Difference?
At first glance, a lap steel and a standard six-string may look similar, but the musical worlds they inhabit are profoundly different. The Hawaiian guitar, played horizontally across the lap, produces a singing, gliding sound defined by sustained notes and intricate slides, while the acoustic guitar provides a percussive, chordal foundation for rhythm and strumming. Understanding the distinction between these instruments reveals unique techniques, histories, and sonic purposes that define their respective roles in music.
The Defining Element: How the Instrument is Played
The most fundamental difference between a Hawaiian guitar and an acoustic guitar lies not in the body shape alone, but in the physical relationship between the player and the instrument.
Laying the Hawaiian Guitar Flat
The Hawaiian guitar, often called a lap steel, is designed to be played horizontally. The musician lays the instrument across their lap, with the strings elevated above the fretboard. This positioning allows the player to use a metal bar or "steel" to press down on the strings, creating a smooth, continuous pitch shift without the need to press the strings all the way down to the fretboard.
Upright Playing of the Acoustic Guitar
Conversely, the acoustic guitar is played in a vertical position. The instrument rests on the player's right leg (for right-handed players) while the left hand frets notes by pressing the strings firmly against the metal frets. This action produces distinct, percussive notes where the pitch is fixed once the string is fretted.
- Playing Position: Horizontal (lap) vs. Vertical (on the leg or strap).
- Finger Interaction: Using a slide (steel) vs. using fingertips.
- String Contact: Pressing the string to the board vs. sliding above the board.
Sound Production: Sustained Notes vs. Percussive Chords
The physical differences in playstyle result in radically different sonic outputs. The Hawaiian guitar is a melody instrument capable of vocal-like expression, while the acoustic guitar is primarily a harmonic and rhythmic tool.
The Sound of the Lap Steel
The Hawaiian guitar is renowned for its gliding, weeping sound. Because the player does not have to stop the string vibration to change notes (as they do with frets), they can bend the pitch up or down, creating a vibrato or a "cry" that mimics the human voice. Notes can be held indefinitely, and multiple notes can be played simultaneously by positioning multiple strings under the steel bar.
"The lap steel allows you to explore that infinite space in between the notes. It’s about the expression of the microtonal bends and the sustain; it’s a very vocal sound."
The Sound of the Acoustic Guitar
The acoustic guitar produces a percussive, rhythmic sound. Because each note is isolated by the fretboard, the instrument excels at chords and strumming patterns. The sound is immediate and staccato; when the string is released, the note stops instantly. While beautiful, it is generally not designed for the long, singing sustain characteristic of the Hawaiian style.
Physical and Structural Differences
While some modern "hybrid" guitars exist, traditional Hawaiian and acoustic guitars have distinct structural features that cater to their specific functions.
Neck and Fretboard Design
Hawaiian guitars typically feature a longer neck and a flat fretboard. There are no raised metal frets to stop the string; the surface is smooth, often just a polished metal bar laid across the strings. This allows the steel to move freely without catching on ridges.
String Height and Action
The "action"—the distance between the strings and the fretboard—is significantly higher on a lap steel compared to an acoustic. This high action is necessary to accommodate the heavy steel bar pressing down on the strings without hitting the fretboard. Acoustic guitars have low action, allowing the player to press the strings down easily with minimal finger pressure.
Resonance and Body Shape
Although both instruments rely on a hollow body to amplify sound, the bracing and resonance differ. Acoustic guitars are built to handle the tension of steel strings and project sound forward for vocal accompaniment. Hawaiian guitars, particularly those designed for the lap, often have a body shape that allows them to rest comfortably on the player's lap while maximizing resonance in a horizontal plane.
Musical Context and Genre
The history of these instruments is tied directly to the music they were born to play.
The Hawaiian Guitar in History
The instrument evolved from the traditional Spanish "guitar de golpe" brought to Hawaii in the 19th century. It was adapted to the musical traditions of the islands, becoming the central voice of Hawaiian music. The style is characterized by slack-key tunings and intricate fingerstyle picking, often telling stories of nature and place.
The Acoustic Guitar in History
The acoustic guitar became a global phenomenon through folk, blues, rock, and pop music. It is the workhorse of popular music, used for strumming accompaniment in a bar setting or intricate fingerpicking in a solo concert. Its versatility makes it one of the most common instruments in the world.
Can the Skills Transfer?
Is it possible to play both? Musicians often find crossover benefits, but the techniques require dedicated practice.
- Fretting Knowledge: A guitarist proficient in standard tuning will understand scales and chord theory, which can aid in composing for lap steel.
- Ear Training: The microtonal bending required for the Hawaiian guitar trains the ear to listen for pitch with extreme precision.
- The Challenge of the Bar: However, the hardest skill to transfer is the concept of replacing the frets with a sliding bar. Learning to control the pressure and position of the steel to achieve a clear pitch is a unique motor skill that does not rely on muscle memory from standard guitar playing.
Ultimately, the choice between the two instruments comes down to the musical goal. The acoustic guitar builds the rhythmic and harmonic landscape, while the Hawaiian guitar paints the melodic colors across it.
