Most guitars have six strings, but the number varies by type
A standard acoustic or electric guitar has six strings. Each string is tuned to a different pitch, from the thickest low E string to the thinnest high E string. This six-string setup has been the norm for centuries and is what most people learn on.
However, not every guitar follows this pattern. Some guitars have fewer strings, and others have significantly more. The number of strings you'll encounter depends on the style of music, the guitar's design, and what the player wants to accomplish. Understanding the differences helps you know what to expect when you pick up an unfamiliar instrument.
Key Takeaways
- Standard acoustic and electric guitars have six strings tuned from low E to high E.
- Twelve-string guitars have six pairs of strings and create a fuller, shimmering sound often used in folk and rock music.
- Bass guitars typically have four strings, though five-string and six-string bass models exist for different playing styles.
- Classical guitars have six nylon strings and are tuned the same as standard guitars but sound warmer and softer.
- Seven-string and eight-string guitars are less common but used in metal, jazz, and experimental music for extended range.
The six-string guitar and how it's tuned
The six strings on a standard guitar are tuned, from thickest to thinnest, as E, A, D, G, B, and E. The thickest string (low E) vibrates slowly and produces a deep sound. The thinnest string (high E) vibrates quickly and produces a high sound. This tuning has remained standard for so long because it balances playability with range—you can play most songs written in the past 200 years without changing the tuning.
Each string can be played open (without pressing down) or fretted (by pressing it against the fingerboard). This gives you dozens of possible notes from just six strings. Beginners start with this six-string setup because the spacing between strings is comfortable for most hand sizes, and the learning curve is gentler than it would be with more strings.
Twelve-string guitars create a richer, fuller sound
A twelve-string guitar has six pairs of strings instead of six single strings. Each pair is tuned to the same note or an octave apart, so when you play one string, you're actually playing two notes at once. This creates a shimmering, chorus-like effect that sounds fuller and richer than a six-string guitar.
Twelve-string guitars are popular in folk, rock, and pop music. You've heard them on countless recordings—they're the instrument that gives songs a bright, jangly quality. The trade-off is that twelve-string guitars are harder to play because the strings are closer together and require more finger strength to press down. They're also more expensive than six-string guitars and need more frequent tuning because the extra strings create more tension on the neck.
Bass guitars typically have four strings
A bass guitar is a different instrument from a standard guitar, even though they look similar. Bass guitars usually have four strings tuned to E, A, D, and G—the same as the four thickest strings on a standard guitar, but an octave lower. The strings are thicker and the neck is longer, which makes the instrument heavier and requires a different playing technique.
Some bass players use five-string or six-string bass guitars to extend their range. A five-string bass adds a low B string below the low E. A six-string bass adds both a low B and a high C string. These are less common than four-string basses but are used in jazz, metal, and progressive music where players need more notes available without moving their hand as far up and down the neck.
Seven-string and eight-string guitars for extended range
Seven-string and eight-string guitars are less common but have a dedicated following in metal, jazz, and experimental music. A seven-string guitar adds one extra string below the low E, usually tuned to B. An eight-string guitar adds two extra strings, typically tuned to F# and B below the standard low E.
These instruments give players access to lower notes and a wider range without having to shift their hand position as much. They're particularly popular in modern metal and progressive rock, where the lower tunings create heavier, darker tones. The downside is that the neck is wider, the strings are closer together, and they take time to adjust to if you're used to a six-string guitar. They're also more expensive and harder to find than standard guitars.
Classical guitars and nylon strings
Classical guitars have six strings, just like standard acoustic guitars, but they're made differently. The strings are made of nylon rather than steel, and the neck is wider and the body is larger. Classical guitars are tuned the same way as standard guitars (E, A, D, G, B, E) but produce a warmer, softer tone.
Classical guitars are used in classical music, flamenco, and some folk traditions. The nylon strings are gentler on the fingers than steel strings, which makes them a good choice for beginners, though the wider neck can be harder for people with smaller hands. The sound is fundamentally different from a steel-string acoustic guitar—it's mellower and less bright.
Specialty guitars with unusual string counts
Beyond the common configurations, some guitars have unusual numbers of strings. A resonator guitar typically has six strings but uses a metal cone inside the body to amplify the sound, giving it a distinctive bright, metallic tone. A lap steel guitar is played horizontally and often has eight to ten strings. A harp guitar can have 20 or more strings, with extra strings that run off the side of the neck and are plucked to create harmonic effects.
These specialty instruments are used in specific genres and playing styles. Most people will never encounter them, but they show how flexible the guitar design is. The number of strings is always a choice made by the instrument's designer based on what sound and playing experience they want to create.
Frequently Asked Questions
Why do guitars have six strings and not a different number?
Six strings balance playability with range. Fewer strings limit the notes you can play; more strings make the instrument harder to play and more expensive. Six strings became standard centuries ago and has remained the default because it works well for most music and most hand sizes.
Can I add more strings to my existing guitar?
No. Adding strings to a standard guitar would require a different neck, bridge, and tuning system. The instrument is built for a specific number of strings. If you want more strings, you need to buy a different guitar—a twelve-string, seven-string, or whatever you're looking for.
Are seven-string and eight-string guitars harder to learn on?
Yes. The wider neck and extra strings make them harder for beginners. Most people learn on a six-string guitar first, then move to a seven or eight-string if they want the extended range. Starting on a six-string gives you better hand positioning and faster progress.
Do all acoustic guitars have six strings?
Most do, but not all. Twelve-string acoustic guitars are common in folk and rock music. Some specialty acoustic guitars have different configurations. If you're buying an acoustic guitar, check the listing or ask—the default is six strings, but you should confirm.
What's the difference between a bass guitar and a regular guitar?
A bass guitar has four strings (usually) tuned much lower than a standard guitar. It's a different instrument with a longer neck and thicker strings. Bass guitars are used to play bass lines that support the harmony and rhythm, not lead melodies like a standard guitar.
