What are the Different Guitar Shapes

One day I decided to look into buying an acoustic guitar. The first thing I thought was what shape should I get? Then I thought:

What are the different guitar shapes? After investigating this is what I found. Parlor, Dreadnought, Jumbo, Auditorium, Grand Auditorium, Grand Concert, Grand Symphony, Grand Orchestra, classical guitar, 3/4 size guitars.

Who new there was so many to choose from. If you want to know the differences in there shapes then see what else I found out about them below.

While there are a lot of chooses in the shape of acoustic guitars. There are some fundamentals that all acoustic guitars have. That is a small body shape produces a smaller sound. Where as Big body guitars have a deeper louder tone. The different woods that are used plays a big part when it comes to the Tone. 


The Dreadnought Guitar Shape

dreadnought

The Dreadnought is one of the most traditional acoustic guitar body shapes. It is considered a large acoustic guitar body shape.

CF Martin Manufactured started it’s line of Dreadnought guitars in 1931. Something I never new about the Dreadnought guitar, but learned while I was checking out all the different shapes is: The Dreadnought was named after a World War 1 battleship.

This style of guitar is a big body guitar. You can find the dreadnought a lot in Country, and Bluegrass music. Musicians like playing the dreadnought guitar for its tonal quality’s. It gives off a louder sound that is a deep more bass tone. This is a great guitar for picking, and even a better guitar for strumming. 

This sound is primarily from the body style of the guitar. Also when the guitar is made the type of wood that is used plays a big part. In the depth of the sound. Martin uses Mahogany or a Rosewood which gives the guitar a Rich tonal quality. 

More manufacturers are going to a more cost effective wood. It’s not uncommon to find on modern day guitars “Stika”. Stika Spruce, a tree which is harvested in southern Alaska forests. 

In 1931 the dreadnought had 12 frets now they have since changed. Modern dreadnoughts have added additional frets on the neck of the guitar. 14, 18, 20, frets. The fretboards are made of Rosewood. A Rosewood fretboard gives the guitar a warm sound when played. 

The dreadnought that Martin made in the 30’s has only gone through some minor changes. Like the scallop brace which does affect the tone of the guitar. The earlier models braces in the inside of the guitar allowed for more bass vibration. Which would in tern carry a Bass tone.


Body Size of a Dreadnought:

Though each manufacture varies in the dimensions. Here is an example so you can get an image in your mind of how big the Dreadnought is. This is a full size guitar. Every shape is based off of the full size and goes down from there.

  • Height Full Size 41″
  • Body length 20″
  • Waist 11″
  • Body width 15.5,”
  • Body depth 4.75″
  • Scale Length 25.5

So you can see this is a thicker, wider, body. Which is great for that big sound that it resonates. But if you are a smaller person this may or may not be the guitar for you.

I find that the thickness of the Dreadnought’s body posses some issues when playing. To me it is a little uncomfortable. That’s just my take on it. Though the sound is very well balanced. The dreadnought low end is very robust, and has the ability to articulate bright treble notes. The dreadnought withstands the test of time.


 Orchestra Guitar Shape

The Grand Orchestra Guitar is a non cutaway guitar like the dreadnought. This guitar has a full size body. It is thinner and does not have as big of a sound as other full size guitars. It has more of a controlled sound. Which makes it a good guitar for recording.

Size does matter when your talking about guitar body shapes. It will make the difference in how comfortable it is when your playing the guitar.

Because this is a full size guitar it may feel a little awkward for a smaller person to play. But since it does have a smaller waist it might be doable. The best thing for you to do is to try the different shapes out in the music store prior to making the leap to buying one.

  • Height 40″
  • Body Length 19″
  • Waist 9.75″
  • Body width 15.5″

You can see that a parlor guitar is about 20% smaller than a full size guitar. You still get the full size quality. In my opinion your getting more from the parlor guitar.

The pro’s are it is easy to play. If you are a smaller person this would be a good guitar for you since it is smaller. There is less of a stretch to get the chords you need.

The only con to this guitar is that it is not as loud as a full size guitar. When you are outside the sound is small. But it is still a great guitar size to have.
