The Brilliance of the Guitar
Used around the world, the guitar is one of the most popular musical instruments of all time. Although there are various types of guitars, they nearly branch out to two categories. For the most part, a guitar can either be electric or acoustic. What’s interesting is the guitar was not always called a huge commodity. During its early years, the guitar used to be called a simple tavern instrument. Now a days, we have two kinds of guitars, and they both are huge commodities. Since electric and acoustic guitars make such broad topics, it’s imperative to understand a little bit about them before comparing and contrasting them.
The earliest documented guitar was in the 14th century but it had three pairs of strings and a fourth single one instead of the modern guitars today. It can be deducted that this first guitar was acoustic for an obvious reason: the history of electronics began in the 19th century, therefore electric guitars are out of the question. It is also theorized that the guitar originated in Spain with its counterpart, the vihuela. A vihuela is an acoustic guitar with twelve strings instead of two. The acoustic guitar started to spread and became very popular amongst European countries in the 16th and 17th centuries. By the late 17th century, a fifth pair of strings had been added below the other four. In the 18th century, the acoustic guitar attained its modern form. Instead of having strings come in pairs, they came in singles. So unlike the vihuela, which had twelve strings, the acoustic guitar ended up only having six with the final sixth string added in the 18th century. Anything beyond the 18th century only improved the construction and the model, which will be mentioned later.
One of the only similarities in acoustic and electric guitars is that they are played almost the same way. The electric guitar is very new in terms of musical instruments. Although the first one was introduced in 1931, it is a young ling compared to the acoustic guitar. This was an early prototype, more like an experiment than a breakthrough. Then in the 1940′s, a man named Les Paul started developing the solid body guitars seen today. As Les Paul started making more models, more people started buying them. With the sound of the guitar electronically amplified so it could be heard throughout a large distance was unheard of at that time. Les Paul later had the guitar model he made named after him, which today is known as a “Gibson Les Paul”. There are many other brands that use the Les Paul model besides Gibson, but they were the first. With the electric guitar out in the streets blues, jazz, and then later known as rock n’ roll begun to be amplified along with perfection of this instrument.
Now oddly enough, the acoustic guitar has many different companies manufacturing it. Along with the mass production of this instrument come different types of models appealing to the public. In terms of style, looks, and construction, the acoustic guitar has poor variety compared to its counterpart, the electric guitar. However, in terms of subcategories, the acoustic guitar wins by a long shot. For example, acoustic guitars branch off into several different types of guitars such as: renaissance, baroque, classical, flamenco, flat-top (or steel string), arch top, Selmer, resonator, 12-string, acoustic bass, Russian, guitarron (large Mexican guitar), Tenor, and harp. All of these are considered acoustic guitars. Since originally the idea was so broad, acoustic guitars were able to be modified into these unique designs that are seen and played today.
To understand anything further on a guitar it is better to first learn the basic anatomy and construction of one. Below is an image of a Gibson Les Paul that shows the basic components of the electric guitar.
The key parts to refer back to in this picture are the body, the pickups, the knobs and the pickup selector. These alone are what make the electric guitar and the acoustic guitar two entirely different instruments.
As said earlier, the biggest difference between the acoustic guitar and the electric guitar is construction. Acoustic guitars are noticeably built in a much simpler way than electric guitars. All acoustic guitars are simple hollow bodied guitars with a neck, strings, and body to sum it up. Instead of electricity, acoustic guitars rely on acoustics oddly enough. The body of the acoustic guitar itself is the sound chamber. Pickups, knobs, and pickup selectors do not exist for acoustic guitars. However, there is such a thing as an electric-acoustic guitar. Even then, the only difference is the acoustic can be plugged into amps while maintaining the acoustic sound.
Electric guitars are much different. The body on an electric guitar acts as a sound chamber as well, but it’s a closed sound chamber instead of an open one like an acoustic guitar. Since electric guitar bodies are enclosed sound chambers, pickups are placed inside to compensate. Pickups are simply magnets that “pick up” the vibration caused when the strings are plucked. This signal is then sent straight into the cord which leads outside of the guitar into the amp (or amplifier). The knobs on the guitar simply control the volume and tone. This is the difference in electric guitars. They are much louder when plugged into an amp, but acoustically the sound is much quieter than an acoustic guitar. In short, electric guitars are for people who like their guitars to sound louder and acoustics are if you want to save some money and still have a decent volume.
Pickups have their own science behind them as well. The quality of the pickups is usually what makes the electric guitar so expensive in the first place. Top notch pickups are around $150 per pair. Some people may even go a step beyond that and purchase a single pickup for $150. All around whenever a guitar is priced, the most expensive parts on the electric guitar are the pickups themselves. The next most expensive part would be the body. Since the body on an electric guitar is made from wood, they are constructed differently depending on the type of wood used. Usually, mahogany is the most expensive wood to be placed on a guitar due to its density. The body actually makes a huge difference in the sound produced by the guitar, which is why different types of wood can heighten the cost of the instrument. The denser the wood, the greater the sound wave that can be produced. For example, in an electric guitar the sound chamber is completely closed off. Even though the sound chamber is completely closed, sound can still escape through the wood. With dense, high quality wood less sound will escape which leaves a better tone to be “picked up” by the pickups which inevitably sends the sound to the amp. Together, with great pickups and a high quality body, the guitar will create the ultimate sound. The same can be said for an acoustic guitar as well. Since the sound waves will not be scattered, it produces a much cleaner sound when played. People may believe that the strings are a deciding factor in how the guitar sounds, but in reality that’s not true at all.
Guitars use strings made out nylon, nickel, copper, and steel. Although there are a variety of strings that can be chosen, the only difference is price. Better strings simply make the guitar easier to play, but they do not play a huge role in sound. The only drawback is strings get dirty and dull after being played awhile and that’s when they affect the sound. This is why people who play guitar regularly should change their strings every two to three months. Knowing these facts makes some people choose acoustic guitars over electric because they are easier to maintain and keep clean.
After taking a look at both types of guitars, it can be concluded that both are extraordinary and are key components to musical history. Today guitars continue to thrive, being bought by people of all ages. It seems quite difficult to imagine any improvements to the guitars seen today, but throughout history there has always been some improvement needed somewhere. Therefore, the peak of guitar lineage is yet to come.

America has always been proud to call itself the land of opportunity, and with this opportunity comes life, liberty, and the pursuit of happiness. There is a reason it is called the “pursuit of happiness” instead of happiness alone. What happens in America while pursuing happiness varies with the individual. The individuals that strive for a future, the individuals that migrate over to this country to make a future all come to America visualizing their dream of finally being able to grasp happiness instead of just pursuing it. With this in mind, parents send their children to school to be educated and sent to college where they can finally begin in their dream career. Even if these kids are not going to college or are achieving their dream in some other way, they are still striving for that dream future. However, some of these individuals went through their lives and ended them just as quickly because of one giant miscalculation. The one question they never bothered to ponder, what if someone came in and took my dream away?
