The guitar origins are in Babylonia and dated back to 1850 B.C as clay plaques were dug up of people playing musical instruments which resembled the modern acoustic guitars showing distinct bodies and necks. Later evidence was found in Ancient Egypt that indicated instruments with marked frets along the neck of a primitive guitar.
How the sound is made:
If you put your finger gently on a loudspeaker you will feel it vibrate - if it is playing a low note loudly you can see it moving. When it moves forwards, it compresses the air next to it, which raises its pressure. Some of this air flows outwards, compressing the next layer of air. The disturbance in the air spreads out as a travelling sound wave. Ultimately this sound wave causes a very tiny vibration in your eardrum - but that's another story.
At any point in the air near the source of sound, the molecules are moving backwards and forwards, and the air pressure varies up and down by very small amounts. The number of vibrations per second is called the frequency which is measured in cycles per second or Hertz (Hz). The pitch of a note is almost entirely determined by the frequency: high frequency for high pitch and low for low .
Page Two: Jayden Foura
The pitch of a vibrating string depends on mass of the string, tension and the length of the string: strings with more mass vibrate more slowly. On steel string guitars, the strings get thicker from high to low. Tension is varied by using the tuning pegs: tighter gives higher pitch. Similarly, shorter string gives higher pitch. The sound produced by the string is faint which is then amplified by it...

...ibrates a little almost like the air in a bottle when you blow across the open lid section of the top. In fact if you sing a note somewhere at F#2 while holding your ear close to the sound hole of the guitar, you will hear the air in the body resonating. This is called the Helmholtz resonance. Another way to hear the effect of this resonance is to play the open (A) string and, while it is vibrating, move a piece of cardboard back and forth across it. This stops the resonance (or shifts it to a lower frequency) and you will notice the loss of bass response when you listen to the sound hole. The air inside is also coupled effectively to the lowest resonance of the top plate.
The Helmholtz resonance of a guitar is due to the air at the sound hole oscillating, driven by the springiness of the air inside the body. This is analysed quantitatively in Helmholtz Resonance.

- Teenagers are incredibly fascinating to learn about, and part of what makes them so captivating, is how complex their brain is. For decades there has been a struggle to understand the inner-workings of the teen brain, and fully grasp how and why teenagers behave the way they do. Now that we have some answers, everything is actually starting to make sense, and we don’t solely have intense adolescent hormones to blame. During Inside the Teenage Brain, Dr. Charles Nelson says “the transition into puberty is analogous to the transition to being a baby.... [tags: Adolescence, Puberty, Cerebrum, Cerebral cortex]

- One needs to understand how a computer works so that one can have a better experience with computers. Understanding the processes that a computer executes can change the way one uses the computer and other interactions with similar technologies. Due to the increasing need of computers in modern society one is more likely to encounter computers which makes basic knowledge of computers essential to interacting with and understanding the world. The sole purpose of the automobile is transportation and understanding how it works can only be applied to a certain amount of interests that many people never get involved in....

- Programming languages are the inner workings of computers, enabling them to accomplish all the amazing things they do today. From the apps on a phone, to the video games on a desktop, and even the operation of microwaves, computers are a major part of our everyday lives. Their languages are separated into five generations determined mostly by a specific radical innovation at the end of a time period that expands from the previous generation; however, these innovations are unique in that new generations don’t cause the previous generations to become obsolete....

- “We define politics as activity related to influencing, making, or implementing collective decisions for a political community”, where as ideologies “ is a package of interrelated ideas and beliefs about government, society, the economy, and human nature that inspire and affect political action (David Close, & Osvaldo Croci, Eric Mintz, 2015, pg 4, pg 55). The different perspectives of each ideology are imperative to the inner workings of global governmental styles. They help in solidifying and justifying certain perspectives of power and influence, while also limiting beliefs and values that are contrary to the “norm”....

- The Inner Workings of Music As a junior in high school, I was fortunate enough to be accepted in the Yale University course: "Music of Arnold Schoenberg, 1908 to 1923: From Romanticism to Dodecaphony" at the Arnold Schoenberg Center in Vienna, Austria. My course work gave me the opportunity to conduct in depth study of the development of one of the twentieth century's most important composers in his home city. However, in Vienna, I also enjoyed many opportunities to learn outside of class.... [tags: Personal Narrative Essays]

- In American society, age eighteen serves as the line between adulthood and childhood. Turning this great age allows one to purchase lottery tickets, skydive, legally sue another individual, and, probably most importantly, vote. With the 2016 elections rapidly approaching, it is imperative that the youth of today have the proper knowledge of politics and the inner workings of governments. Unfortunately, many Americans -- whether it be young or old -- rarely seem to recognize how some of their most esteemed politicians fail in one of the most important fields when vying for leadership: morality....

Jeffrey Toobin is a staff writer for the New Yorker, as well as, a CNN senior legal analyst. “The Nine” starts in the Reagan and ends in 2007. Toobin discusses all the major cases that the Supreme Court made a ruling on during that time period. He also talks about each of the Justices, their personalities and how they came to make the decisions they did. One of the things that I found most interesting about the book was that Toobin described how the Justices became Justices.... [tags: inner workings of the Supreme Court]

- Electric guitars play a very important role in today's music. Without it, we would be stuck with the acoustic guitar, which has limited volume, and a narrow range of sounds it can produce. Understanding just exactly how the electric guitar works isn't as intuitive as with the acoustic. With this website, I attempt to brighten the knowledge people have on the physics behind the electric guitar, since one cannot appreciate something, truly, until he knows how it works. The Acoustic guitar, originating from Spain, has been around since the 1500s.... [tags: physics music guitar]

- Almost everybody can appreciate guitars. Guitars are at the forefront of music as the centerpiece of most bands. Guitars are a highly versatile instrument capable of playing full 6 note chords, unlike most instruments. As much as music depends on guitars, guitars also depend on physics. Without understanding the properties sound, guitars wouldn’t be possible. Guitars use the principles of acoustics to produce the sound you hear. Acoustic guitars and electric guitars produce sound in two different ways.... [tags: physics guitar]
