This isn’t your usual guitar. The Guitar Phím Lõm may have come from the West, but Vietnam made it its own. With deep, sliding notes that almost sound like a voice crying, this instrument tells stories no regular guitar could ever tell.

- Where it came from and how it evolved
- How it’s played, and what other Vietnamese string instruments share the stage

What Makes the Vietnamese Guitar Phím Lõm Unique?
At first glance, the Vietnamese guitar, Guitar Phím Lõm looks like a regular six-string guitar. But look closer at the neck, and you’ll see something strange. The wood between the frets is scooped out, curved like a shallow bowl. That curve is what gives the Guitar Phím Lõm its voice.


Why the Frets of Vietnamese Guitars Are Scalloped
When a luthier carves out the fingerboard wood between frets, it lets your fingertip press the string deeper, not flatter. This means you can bend notes up or down microtonally, by tiny steps creating weeping slides and vibratos you won’t hear on a Western guitar.
Unlike a standard guitar, where frets act like strict borders, the scalloped spaces in a Vietnamese guitar let you glide across emotional terrain. It’s almost like combining a guitar with a fretless violin or even a theremin.
Comparison Table: Standard Guitar vs. Guitar Phím Lõm
Feature | Standard Guitar | Guitar Phím Lõm |
---|---|---|
Fretboard | Flat | Scalloped between frets |
String Bending | Limited to 1–2 semitones | Up to 3+ semitones, microtones |
Playing Style | Press frets | Pull into scallops, vibrato-heavy |
Sound Character | Clean, precise | Wavy, expressive, crying-like |
Primary Use | Western genres | Cải lương, Vietnamese opera |
How Did It Emerge in Southern Vietnam?
In the late 1800s, French colonizers brought classical guitars to Vietnam. But local musicians didn’t just copy what they saw, they changed it.
They took the six-string instrument and modified the fretboard to serve vọng cổ (nostalgia songs). These were deeply emotional tunes full of sliding and bending melodies. Standard frets couldn’t capture that raw emotion. So Vietnamese players carved out the fretboard, letting them dip into notes the French never imagined.
Over time, this evolved into the modern Guitar Phím Lõm, rooted in the folk theater known as cải lương. In these live performances, the guitar isn’t just background music, it acts like a singing partner to the actor.
Cải lương translates to “renovated theater,” but it’s more than that. It’s a blend of traditional Vietnamese drama and Western harmony, and the guitar sits right in the middle of that blend.
Cultural Insight
In Southern Vietnam, this guitar became more than a novelty, it became the sound of heartbreak, love, longing, and rural storytelling.
What Techniques Do Players Use?
You can’t play a Vietnamese guitar (Guitar Phím Lõm) the same way you play your steel-string at home. Here’s why:


Microtonal Bending
Instead of just pressing down on a fret, you pull or push the string deeper into the scallop. This stretches the pitch gradually. Think of it like singing a note and sliding into another, it’s smooth, fluid, and emotional.
Vibrato
With those deep scallops, vibrato becomes wavy and wild. You can mimic the human voice or even the Vietnamese đàn bầu (a one-string instrument famous for its tremolo).
Playing Tip
Want to try the feel? On your Vietnamese guitar, very lightly place a finger between two frets. Slide it while plucking the string. Now imagine being able to bend that note while keeping the string in one spot, that’s what scallops let you do.
Listen to It in Action
You can hear this technique best in recordings of vọng cổ ballads. The guitar doesn’t just follow the singer, it answers them, echoes them, and sometimes mourns alongside them.

Frequently Asked Questions about the Vietnamese Guitar (Guitar Phím Lõm)
1. What does “Guitar Phím Lõm” mean in English?
It means “guitar with sunken frets.” The word phím means fret, and lõm means sunken or indented. It refers to the scalloped shape carved into the fretboard, allowing deep bends and expressive slides you won’t get on a regular guitar.
2. Is the Guitar Phím Lõm used only in Vietnam?
Yes, it’s mostly played in Southern Vietnam, especially in cải lương (renovated theater). However, some modern musicians in the Vietnamese diaspora and experimental artists globally are starting to explore it, too, especially for its microtonal bending ability.
3. Can I modify my own guitar to be like a Guitar Phím Lõm?
Yes, but it’s not for beginners. You’d need to scallop the fretboard carefully, which is a permanent change. It’s best to try this on a low-cost guitar or have it done by a professional luthier who understands Vietnamese-style modifications.
4. What music styles use this Vietnamese guitar?
Vietnamese guitars mainly used in vọng cổ, a traditional Southern Vietnamese song style, and in cải lương, a mix of spoken drama, folk opera, and music. Some experimental artists blend it with jazz, fusion, and ambient genres.
5. What’s the difference between a scalloped fretboard and a fretless guitar?
A scalloped fretboard still has frets, you’re just removing the wood between them. A fretless guitar has no frets at all. The scalloped design lets you press deeper, bend more, and glide across pitches while still using frets for note positions. It gives you control without losing precision.
6. Is it hard to learn to play a Vietnamese guitar?
It depends. If you’re used to standard guitar playing, it might take time to adjust your touch. You need lighter pressure, strong ear training, and control over micro-bends. But once you get the feel, it opens a whole new world of expression.
