The classical guitar has nylon strings, a wide, flat neck, and a warm, mellow sound, while the acoustic guitar (also known as the Western guitar) has metal strings, a narrower neck with a reinforcement bar, and a louder, brighter sound. Both instruments are acoustic in the physical sense—they can be played without an amplifier—but in stores and in everyday speech, "acoustic" refers to a steel-string guitar. These differences in design affect playing comfort, repertoire, and the choice of a first instrument.
To sum it up
- Strings: classic – nylon (bass with metal braiding), acoustic – steel.
- Vulture: wider in the classic version (usually about 52 mm at the threshold), narrower in the acoustic version (usually about 43 mm) and with an adjustment rod.
- Sound: Classical – warm and soft, acoustic – loud, bright and resonant.
- Don't use steel strings on a classical guitar. - it is not designed to tension them.
Classical and acoustic guitar – why the confusion in names?
Strictly speaking, the term "acoustic guitar" refers to any guitar that produces sound through a resonator, without the use of electronics. In this sense, a classical guitar is also acoustic. However, in practice—in music stores, schools, and in conversations— - An acoustic guitar is a guitar with steel strings. , also known as Western guitar or folk guitar. The classical guitar, on the other hand, is a nylon-string instrument originating from the Spanish tradition. In this article, we use this colloquial classification.
Strings - nylon or steel?
This difference determines almost everything. classical guitar Nylon strings: the three treble strings are smooth, while the three bass strings have a synthetic fiber core wrapped with thin metal wire. Nylon is soft, pleasant to the touch, and has low tension.
Acoustic guitar The strings are steel (usually with bronze or phosphorus-bronze wrappings on the thicker strings). They have a much higher tension and produce a louder sound with richer high frequencies, but they can cause finger pain when learning to play, and over time, calluses can form on the fingertips.
The difference in tension is due to the way the strings are attached. In a classical guitar, the strings are strung and tied to the bridge , and then wound onto crossbars through oblong holes in the headstock. In an acoustic guitar, the strings have a metal ball at the end, which is secured in the bridge with a pin, and at the headstock, they are wound onto tuning pegs mounted in the solid wood.
Construction of the neck, shaft and body
Classical guitar neck wider and flatter - Typically around 52 mm at the nut. Wider string spacing facilitates fingerpicking and classical technique. Acoustic guitars typically have necks around 43 mm, which is thinner and more comfortable for playing chords, especially for those with smaller hands.
On a classical guitar, the neck is usually connected to the body at the 12th fret , and on most acoustic guitars - on 14th fret (Although there are also acoustic designs with "12 frets"). This makes it easier to access the upper frets on an acoustic guitar.
Steel strings put a lot of tension on the neck, so acoustic guitars have a truss rod inside. kernel , allowing you to adjust the curvature of the neck. A truss rod is usually unnecessary in a traditional classical guitar, as nylon strings have low tension. Acoustic guitar bodies come in a variety of shapes—for example, dreadnought, jumbo, and auditorium—and often feature a pick guard under the soundhole to protect the body from picking.
Sound and playing style
The classical guitar has warm, rounded and soft sound. It is most often played with the fingers. It is an instrument used in classical music, flamenco (which uses a slightly different construction), bossa nova, and many campfire songs.
The acoustic guitar sounds louder, brighter and more percussive . It's perfect for pick chord accompaniment, folk, country, pop, rock, and original songs, as well as fingerstyle playing. Many models feature a built-in pickup and are available in electro-acoustic versions.

Which guitar should I start with?
- Choose classical strings, If you're starting music school, want to play classical music or flamenco, or need soft strings that reduce finger chafing. Classical strings also come in smaller sizes (e.g., 1/2, 3/4) for children.
- If you dream of accompanying pop, rock or folk songs, playing with a pick and enjoying a strong, bright sound, choose an acoustic guitar . A narrower neck is often more comfortable for chords.
- Be guided by the music you want to play – motivation is more important than which tool is «easier».
- Don't change the type of strings . Steel strings on a classical guitar can damage the neck and bridge, while nylon strings on an acoustic guitar will sound bad and won't hold well in the bridge.
- Before purchasing, it's worth playing the instrument or asking a teacher to check whether the strings are too high and whether the guitar is tuned correctly at the higher frets.
Frequently Asked Questions (FAQ)
How to distinguish a classical guitar from an acoustic one?
The fastest way is through the strings and headstock. A classical guitar has nylon strings (the top strings are clear or cloudy) and a headstock with two oblong holes. An acoustic guitar has metal strings, a solid headstock with tuning pegs, and bridge tuning pegs.
Which guitar is best for a beginner?
There's no single answer. Classical guitars have soft strings that are less likely to abrade your fingers, making them the standard choice in music schools. Acoustic guitars have a narrower neck and are better suited for pop or rock music. It's best to choose an instrument based on the type of music you want to play.
Is it possible to install metal strings on a classical guitar?
No. Classical guitars typically don't have a truss rod and aren't designed for high-tension steel strings. Installing them could cause the neck to warp or the bridge to break.
Is a classical guitar also an acoustic guitar?
Technically, yes—both guitars play without an amplifier thanks to their resonant bodies. However, colloquially, an "acoustic" guitar is one with steel strings, while a "classical" guitar is one with nylon strings.
What is the difference between an acoustic and an acoustic-electric guitar?
An acoustic-electric guitar is an acoustic guitar with a built-in pickup and often a preamplifier. It can usually be played without power, but can also be connected to an amplifier or PA system.
