The guitar is a string instrument in the chordophone family
The guitar belongs to the chordophone family, which is the broad category for any instrument that makes sound by vibrating strings. Within that family, the guitar sits in a smaller group called lutes — instruments with a neck, a body that amplifies sound, and strings that run the length of the neck. The strings vibrate when plucked or strummed, and the hollow body resonates to project that sound into the room.
This classification system comes from musicology, the study of music and instruments. It helps musicians and builders understand how different instruments work and relate to each other. The chordophone family includes everything from harps and pianos to violins and banjos — any instrument where strings are the sound source.
Key Takeaways
- The guitar is classified as a chordophone, the family name for all string instruments that produce sound through vibrating strings.
- Within the chordophone family, the guitar is a lute — an instrument with a neck, a resonating body, and strings stretched across both.
- The guitar's design allows the player to change pitch by pressing strings against frets on the neck, unlike harps where each string has one pitch.
- Acoustic and electric guitars are both lutes; the difference is how the vibration is amplified, not the fundamental instrument family.
How the lute group differs from other string instruments
The lute family — which includes guitars, mandolins, banjos, and ukuleles — shares a specific design: a neck attached to a resonating body. This design lets a player change the pitch of a single string by pressing it against frets or the fingerboard, shortening the vibrating length. A harp, by contrast, has no neck and no frets; each string is tuned to one pitch and cannot be changed by the player's hand position.
Pianos are also chordophones, but they work differently. A piano player strikes strings with hammers rather than plucking or strumming them. Violins and cellos are bowed string instruments — the player draws a bow across the strings to make them vibrate continuously. The guitar's method — plucking or strumming with fingers or a pick — is what defines its place within the lute group.
Why classification matters for understanding how a guitar works
Knowing the guitar is a lute explains why it has a neck with frets. The frets are markers that show where to press the string to hit a specific note. A harp has no frets because the player cannot shorten the strings — each one is already tuned to its own pitch. A violin has no frets either, but for a different reason: the player's ear and hand position determine the pitch, and the bow keeps the string vibrating continuously.
The chordophone classification also explains why the guitar's body shape matters. The hollow space inside an acoustic guitar acts as a resonator — it amplifies the vibration of the strings so the sound carries across a room. An electric guitar has a solid body because the vibration is picked up by a magnetic pickup and sent to an amplifier instead. Both are still lutes, still chordophones, because the sound originates from vibrating strings.
How the guitar compares to other lutes
The mandolin is a lute with a shorter neck and fewer strings than a guitar, and it produces a higher pitch. The banjo is a lute with a drum-like head stretched over a circular frame instead of a wooden body — the head vibrates along with the strings to create a brighter sound. The ukulele is a small lute with four strings, originally from Hawaii. All of them share the core design: a neck, frets, and a body that resonates.
The classical guitar, the steel-string acoustic guitar, and the electric guitar are all the same instrument family — they are all lutes, all chordophones. The differences are in materials, string type, and how the sound is amplified, but the fundamental design and how the player produces sound remain the same.
Where the guitar sits in the larger musical world
Musicologists divide all instruments into families based on how they make sound. The five main families are chordophones (strings), aerophones (wind), membranophones (drums and percussion with a stretched membrane), idiophones (percussion that vibrates as a whole, like bells or xylophones), and electrophones (instruments that use electricity to generate sound). The guitar is firmly in the chordophone group because its sound comes entirely from vibrating strings.
Within Western classical music, the guitar is sometimes called a plucked string instrument to distinguish it from bowed strings like the violin. In world music traditions, the guitar's lute family includes instruments from many cultures — the oud from the Middle East, the sitar from India, and the pipa from China are all lutes, even though they look and sound quite different from a Western guitar.
Acoustic versus electric: same family, different amplification
An acoustic guitar and an electric guitar are both lutes and both chordophones. The acoustic guitar uses its hollow wooden body to amplify the string vibration naturally — the sound bounces inside the body and exits through the sound hole. An electric guitar uses a solid body and a magnetic pickup that converts the string vibration into an electrical signal, which then travels to an amplifier.
The amplification method is different, but the core instrument is the same. Both have a neck with frets, both are played by plucking or strumming strings, and both produce their sound from vibrating strings. This is why a guitarist can pick up either type and play it using the same techniques — the family relationship is real and functional, not just a label.
Frequently Asked Questions
Is a guitar the same family as a violin?
Both are chordophones, so they are in the same broad family. But a violin is a bowed string instrument, while a guitar is a plucked lute. The violin has no frets and no neck in the guitar sense — the player's hand position on the fingerboard determines the pitch. They work very differently even though both use vibrating strings.
Why does the guitar have frets and a harp doesn't?
A harp's strings are each tuned to one pitch and cannot be shortened. A guitar's frets let the player press a string against the fingerboard to shorten it and raise the pitch. The fret design is part of what makes a guitar a lute — it allows one string to play many different notes.
Is a bass guitar in the same family as a regular guitar?
Yes. A bass guitar is a lute and a chordophone, just like a standard guitar. The main difference is size and string thickness — a bass guitar has thicker strings tuned lower, and a longer neck to accommodate them. The design and how it produces sound are the same.
What makes something a chordophone instead of another instrument family?
A chordophone is any instrument where vibrating strings are the primary sound source. If the sound comes from a vibrating membrane (like a drum), a column of air (like a flute), or the instrument body itself (like a bell), it belongs to a different family. The guitar qualifies as a chordophone because the strings do all the work.
