Physics of Electric Guitars Essay

The way energy travels is by vibrating in waves which can either be a path through longitudinal or transverse waves. These waves are the path to transferring energy. Longitudinal waves travel and vibrate in a

A guitar is an instrument made out of wood or other wood like materials. Many things could affect the instrument's qualities, such as the types of lacquer used or what kind of strings are used. The guitar amp is an instrument in itself just as a guitar, not all amps are created equally. An amplifier allows the guitarist to express his playing to the world. Some amplifiers are made using really simple vacuum tube circuits, and others are made from really complex solid state circuitry. Not any two similar guitars will sound alike, just as how any two similar people are not exactly identical. Amps are very similar in context; no two similar amps will sound exactly alike.

A guitar pickup consists of a permanent magnet (usually with a material core such as ceramic or alnico) which is wrapped by a tight copper coil of many turns (several thousands). The pickups are mounted onto the body of the guitar below the strings which make contact.

The history of the way we listened to music started off as music boxes invented on January 1,1811 in a small little swiss town. Next came the Phonograph invented by Thomas Edison on November 21, 1877 which recorded and produced sound. Later came the Gramophone invented by Emily Berliner. The first Jukebox was invented November 23, 1889. A radio station was invented November 2, 1920. 8 Track was invented into cars on January 1, 1964. Cassettes were invented January 1, 1971. Boom boxes was invented January 1, 1976 you could take it anywhere with you. Lastly the Walkman comes along in 1979 created by Sony .

through electromagnetic induction which create resistance, and in turn either heat or electricity. In this

A pulley was attached to the end of a lab table. The total length of the string used in the experiment was measured before the first knot and weighed by a lab balance. The linear mass density was calculated using the following equation: µ= m/Lo. Then, the pre-measured string was tied to a string vibrator and a mass hanger (hanging from the pulley by the string) with the pulley parallel to the surface of the table. The length of the string that was able to undergo vibrations was measured by a meter stick. Next, the vibrator was turned on and a variety of standing–wave patterns were produced by gently pulling down on the mass hanger. All results were recorded.

Guitars have many models, in all different shapes, sizes, and colors. Some of the oldest guitar-like instruments were the bowl harp and tanbur. Bowl harps were made of tortoise shells or calabashes as resonators, or amplifiers, for their hollow shape. The neck was made of a bent stick, with strings made of gut or silk. The tanbur was “a long-necked string instrument with a small egg or pear shaped body, with an arched or rounded back, usually with a soundboard

Magnetism can attract magnetic objects or push them away. Magnets have a magnetic north pole and a magnetic south pole. If the same pole of two magnets are placed near each other they

In the years between 1877 and 1900 music and music technology started to spread out and become better known to the people around the world and in their own households thanks to the phonograph. It all started in 1877 when Thomas Edison Invented the phonograph It was the first device that could record sound and play it back. the phonograph helped many musicians make their music known to others around the world and also helped them rise to fame. It also helped introduce new types, styles and range of music to the people like in 1890 the very first native american music was recorded. After the phonograph 20 years later in 1897 the gramophone was made. The gramophone was made by Emile Berliner like

This is the way the magnetic energy generator works in creating electricity. The fundamental understanding in mastering on how to generate cheap electricity is always that, like magnet rods repel one another while opposite rods attract one another. You will find some magnetic forces that are within the generator. These forces will push off against one another to be able to make the magnetic energy. Indeed if they could push against one another more, its keep is going to be a rise in producing magnetic

The Venetian cutaway of this acoustic guitar allows the left hand to access the frets farther up towards the sound hold. These higher fret are otherwise a challenge to reach, making this guitar well suited for electric guitarists going unplugged. Additionally, the smaller 24-7/8 inch scale length reduces the string tension,

With the increased pressure to "go electric," many artists who played the guitar at the height of the Rock n Roll movement switched their acoustic instruments to electric versions. Unlike bass guitars, which can often be converted into electric basses, a purely electric guitar will not produce melodic sounds without the help of an amplifier which carries the tune produced through an electronic current. Electric guitars also allow the player to partially manipulate the sound coming to the amplifier through equalizing, distorting, and other methods.

The basic principle of the device created In this module is not a new one, battery powered guitar amplifiers are popular among many guitarists and have been for many years. Popular products currently in the market place range from cheap, products featuring low quality questionable design, through to expensive, boutique and custom work, created by audio engineers across the UK and USA. Such devices are as stated below:

One of the largest contributors to electronic music today is Thaddeus Cahill (Lejaren Hiller, Electronic Music). His telharmonium was created with an assembly of rotary generators and telephone receivers to convert electronic signals to into sound (Lejaren Hiller). He developed his invention from 1895 and continued to work on it even though there were no ways for the sounds being created from the electrical signals to be heard. Speakers or amplifiers were non-existent for some time even after the development of Cahill’s invention, and “his instrument was the ancestor of present-day electronic music synthesizers” (Lejaren Hiller, Electronic Music). Furthermore, Cahill’s invention spurred the development of other electric instruments such as the electronic organ. In the 1920s, more electronic instruments were invented, some of which being monophonic meaning that only one note could be played at a time (Lejaren Hiller, Electronic Music). One of the more common monophonic electric instruments was the theremin invented by Russian scientist Leon Theremin (Britannica, Theremin Musical Instrument). The theremin produces sine waves and is a” box with radio tubes producing oscillation at two sound wave frequencies above the range of hearing; together they produce a lower audible frequency equal to the difference in their rates of vibration (Britannica, Theremin Musical Instrument)”. By moving one’s hand or a wand in front of the antennas, one could control the pitch played by the

First, I will discuss the history of the guitar; when it started, the miraculous evolution, and the manufacturers that took the industry by storm. Although there are many theories, the history is hazy as to exactly where the first known guitar came from prior to the 16th century. According to the book A Concise History of the Classic Guitar by Wade Graham, Hittite stone carvings in Turkey; dated 1300 BC, eludes to the possibility of a similar instrument, as well as mentions in the old testament of long-necked lutes in Mesopotamia. In Greek mythology; Fourth Homeric Hymn, mentions the use of a stringed instrument made of cow gut and turtle carcass. History becomes a lot clearer around the 16th century, when printed literature became available. According to acousticmusic the Baroque period is when the guitar really began to gain popularity, and was commonly used to accompany vocalists. Guitar music began to grow and evolve; the Classical period lasting from 1730-1820, and the Romantic period of 1815-1910 gained more popularity and diversity and was soon known worldwide. Other
