What Is Bracing On a Guitar

Every acoustic guitar has bracing and this bracing has an effect on the tone and strength of the guitar.

Different types of bracing will give the guitar a unique tonal character and some bracing methods are better than others.

What is Bracing on a Guitar?

Bracing is essentially strips of wood – or more accurately wooden struts – that are attached the underside of the guitar’s soundboard (aka top) and the guitar’s back.

Why Is Bracing Important

The bracing is important as it adds necessary strength to the top and back of the guitar.

However important that bracing is for strength, it is also important for the tone and important that the bracing does not adversely affect the sound – in particular it needs to support and not restrict the vibrations of the soundboard.

A balance needs to be struck between adding enough strength for the guitar to handle the pressure exerted by the strings and so that any distortion is minimized and also allow the top vibrate enough to respond properly and produce the right amount of vibration.

When done well bracing can add to the sound of a guitar – and give the guitar a unique character. When done poorly it can worsen the sound of the guitar.

Common Types of Bracing

Scalloped Bracing

You might of heard of scalloped bracing before but maybe weren’t quite sure what that meant.

Scalloped bracing uses wooden struts that are scooped out in order to reduce weight and allow the guitar to vibrate more.

Scalloped bracing allows guitars to be louder and bassier than they would be without the scalloping.

You might also have heard of X Bracing – so what is this?

X bracing is essentially bracing that makes and X shape on the underside of the top of the guitar. The “X” typically intersects just below the soundhole and the “legs” of the X are typically longer than the arms (see image to the right)

There are other wooden struts too but the X forms the main part of the bracing.

X Bracing is very common, structurally strong and is said to produce a balanced tone.

There are lots of variations on X Bracing as you can imagine. Martin is said to have invented this type of bracing and it’s now widely used by a lot of brands. For example, check out Taylor’s variations on X Bracing.

What Wood is Best for Bracing

Top bracing is most commonly made from spruce, regardless of the tone wood used for the top itself. The wood for bracing needs to be light but strong and spruce fits this bill well. Bracing for the top is the most important bracing in terms of the tone of the guitar.

Back bracing is sometimes also made from Spruce but is made from other woods too. it’s not as important as the top’s bracing so the wood used isn’t as important either. Back bracing’s main function is for strength.

Final Thoughts on Guitar Bracing

Bracing is often regarded as the most important factor that influences the unique sound of an individual guitar.

It can’t be seen from the outside so it hides away as a guitar’s unsung hero in determining its tonal qualities but make no mistake that each guitar brand puts considerable thought and research into bracing techniques to achieve a better, more balanced, more responsive, more dynamic and more unique sound.

FAQs

What does bracing do in a guitar?

Bracing in a guitar is a crucial element that contributes to the instrument’s sound, structural integrity, and playability. Luthiers carefully design and implement bracing patterns to achieve a balance between stability and vibration responsiveness, resulting in a guitar with distinctive tonal qualities and characteristics.

Which guitar bracing is best?

The “best” bracing pattern depends on your musical preferences, the style of music you play, and the specific tonal qualities you’re seeking. It’s a good idea to try guitars with different bracing patterns and play them to determine which one resonates with you the most. If you’re unsure, consulting with experienced guitarists, trying out various guitars, and seeking guidance from professional luthiers can help you find a bracing pattern that aligns with your musical goals.

Nate is just your average (above average) guitar player. He's no Joe Satriani, Jimi Hendrix or Jimmy Page - wait this site is about acoustic guitars (sorry) He's no Django Reinhardt, Chet Atkins, or Michael Hedges, wait? who!? He's no Robert Johnson, Eric Clapton or Ben Harper - more familiar? Anyway you get the point :-)

  1. I run a guitar site as well. I love playing guitar and found your site very informative. Bracing is so important. I will bookmark your site and come back to it to always be learning to better my site. Wish you all the best with your site and hope your guitar playing is going well too!

    1. Hey Blake

      Great to meet a fellow guitar site runner! Thanks for visiting and I’m glad you are able to sixstrinacoustic as a resource for your own site – all the best with your guitar site too. Chuck me your URL – I’d be keen to check it out.

  2. I will never look at a guitar the same way. I have played the instrument since high school but it’s the first time I really notice how it is structured inside, and what types of bracing they use. Great info.

    I have a friend who collect electric guitar pieces everywhere and assemble them together to make his own customized guitar. I wonder if he knows about that stuff.

    1. Hey guy.

      Yeah the bracing is pretty important in determining the tone of an acoustic guitar.

      With electric guitars they don’t have bracing – the body of the guitar is solid wood. This is because it doesn’t need to be hollow inside because it isn’t designed to produce sound without an amp. Since there is no need for acoustic sound, there’s no need for a hollow body and therefore no need for bracing.

  3. I’m actually building an acoustic guitar now, didn’t know about how the wood used for bracing would damage the tone .
