Acoustic vs. Classical Guitar: What are the major differences?

While a classical and an acoustic guitar both visually look similar — with a construction including six-strings tuned EADGBE, a soundhole, and tuning pegs — many of these similarities function differently. Before you dive into playing or purchasing a classical guitar, let’s go through a few key differences you should keep in mind.

Shape

Most acoustic guitars come in a dreadnought shape in a standard parlor size. Parlor size guitars are typically smaller than a classical guitar, but some are larger depending on the type of acoustic guitar manufacturer.

Neck

Typically, a standard classical guitar has a wider neck than an acoustic guitar. Remember that an acoustic guitar is meant for strumming or fingerpicking; therefore, the smaller neck widths and shorter string spacing make these techniques easier for players. It’s also best to keep in mind that classical guitars tend to not have fret markers, which may or may not pose a challenge to players.

Bridge

A classic wrap-around bridge is used on a standard classical guitar. On this type of guitar, the strings are tied in a knot around the bridge to secure them in place, similar to a ukulele. But classical bridges also accept ball-end classical strings, which is the preferred string method for these types of rigs. In contrast, the bridge on an acoustic guitar has pegs that securely hold the strings in place.

Strings

The ultimate difference between an acoustic and a classical guitar is the strings. Classical guitars use nylon strings as opposed to steel strings on an acoustic guitar.

This is where the major differences in sound come from. Nylon strings are a lot thicker and produce a more mellow, softer sound than steel strings. The treble strings (G, B, high E) are made with nylon monofilament while the bass strings (E, A, D) feature a silver-plated copper wrapped around a nylon multifilament core. Nylon strings are softer to the touch and have a plastic feel, which makes them ideal for beginners.

While the nylon strings might be easier to play for uncalloused hands, the sound is not as common in modern music. If you like Spanish, Flamenco, or classical music, this type of sound can be achieved with a classical guitar. But most modern rock, folk, blues, and country performers use an acoustic guitar.

The steel strings on an acoustic guitar produce a bright, crisp, even twangy sound that resonates more than a classical guitar. Acoustic guitar strings are manufactured in a variety of metals and materials, including nickel and bronze. These strings are thinner, making them extremely similar to electric guitar strings while also being somewhat sharper on the fingers.
