How Guitars Work To properly understand the principles of how a guitar works, it is essential to understand the functions of sound waves and electromagnets. They play a key role in the function of the guitar, both in the acoustic and the electric. Sound Waves For us to hear, we need ears with an important piece, the eardrum. We hear sound because when a sound is created, there is a change in air pressure. Because of this change in pressure, waves are produced, flying all over the place. On the guitar, when the string vibrates, the change in air pressure causes the air particles to move around. There are air particles all around us, so when the sound wave crashes into these particles, they all collide until they reach our eardrums. When the air particles crash into our eardrum, they will hit against all the other components of the ear and the sound will enter our brain. Electromagnets Electromagnets need a source of energy (a battery, power outlet, etc.) In the electric guitar (because in the acoustic, electromagnets are inexistent) the power source comes from the amplifier, which gets its electrical current from a power outlet. Together, the electrical flow is made by the constant flow of electrons (e-). When the plug from the amp is attached to a source of energy, the electrons will flow to and through the wire. Basically, all an electromagnet does is collect electrons and sends them into a constant flow. What the electromagnets have to do with the guitar will be explained in detail at the Electric Guitar page. The Differences Between Acoustic And Electric Guitars Both electric guitars and acoustic guitars are great instruments that are the most commonly used in music. They have many similarities.

  • Music and the Brain

    2088 Words  | 5 Pages

    For any individual who either avidly listens to or performs music, it is understood that many melodies have amazing effects on both our emotions and our perception. To address the effects of music on the brain, it seems most logical to initially map the auditory and neural pathways of sound. In the case of humans, the mechanism responsible for receiving and transmitting sound to the brain are the ears. Briefly stated, the outer ear (or pinna) 'catches' and amplifies sound by funneling it into the ear canal. Interestingly, the outer ear serves only to boost high frequency sound components (1). The resonance provided by the outer ear also serves in amplifying a higher range of frequencies corresponding to the top octave of the piano key board. The air pressure wave travels through the ear canal to ultimately reach and vibrate the timpanic membrane (i.e.-- the eardrum). At this particular juncture, the pressure wave energy of sound is translated into mechanical energy via the middle ear. Here, three small bones, the ossicles, vibrate in succession to produce a unique pattern of movements that embodies the frequencies contained in every sound we are capable of hearing. The middle ear is also an important component in what music we actually keep out of our 'head'. The muscles grasping the ossicles can contract to prevent as much as two thirds of the sound from entering the inner ear. (1, 2)

    The guitar is a typical string instrument, whose physics are similar to many other string instruments. The main parts consist of the body, the neck, the bridge, the tuning pegs, the sound hole, and the strings. An electric guitar lacks the sound hole and instead relies on an amp for amplification. The physics of a guitar involves sound waves, how they are amplified, and how they travel.

    Guitars are very different instruments than they once were. They have had many changes in shape, sound, style, and how they are made. Starting out as tortoise shells with a stick and some strings, they have now developed into acoustics, spread from Europe to the rest of the world, and turned out to be the crazy shaped, cool designed electric guitars of today.

    A conductive atom’s valance shell is not completely full; electrons will flow from atom to atom because of this. When these electrons move from one atom to another, that is electrical current (a brief description of that is). A magnet can be made from different materials, but a loadstone is the natural form. The most important part of magnetism to make electric motors work is: A magnet has two different ends, or poles, a north and a south pole. These poles behave like electric charges, like poles repel and unlike poles attract although magnets have no effect on still charges.

    Sound waves are everywhere. A very big thanks to the ears, thanks for to the ears for receiving the vibrations that are caused by objects, which travel through material to get to the ears, which will send a message to the brains about the vibrations and how to read them. Sounds are just a form of vibrations. Those vibrations cause many feelings, many emotions, many changes in attitude. Its funny to find out that a beautiful song, is only a mixture of many vibrations making paths through the medium, with different type of pitches and force, that our ears are receiving and transmitting into a beautiful song.

  • Electromagnetic Induction

    2435 Words  | 5 Pages

    The phenomenon called electromagnetic induction was first noticed and investigated by Michael Faraday, in 1831. Electromagnetic induction is the production of an electromotive force (emf) in a conductor as a result of a changing magnetic field about the conductor and is a very important concept. Faraday discovered that, whenever the magnetic field about an electromagnet was made to grow and collapse by closing and opening the electric circuit of which it was a part, an electric current could be detected in a separate conductor nearby. Faraday also investigated the possibility that a current could be produced by a magnetic field being placed near a coiled wire. Just placing the magnet near the wire could not produce a current. Faraday discovered that a current could be produced in this situation only if the magnet had some velocity. The magnet could be moved in either a positive or negative direction but had to be in motion to produce any current in the wire. The current in the coil is called an induced current, because the current is brought about (or “induced”) by a changing magnetic field (Cutnell and Johnson 705). The induced current is sustained by an emf. Since a source of emf is always needed to produce a current, the coil itself behaves as if it were a source of emf. The emf is known as an induced emf. Thus, a changing magnetic field induces an emf in the coil, and the emf leads to an induced current (705). He also found that moving a conductor near a stationary permanent magnet caused a current to flow in the wire as long as it was moving as in the magnet and coiled wire set-up.

  • Acoustic Guitar: My Music, Over The Electric Guitar

    1521 Words  | 4 Pages

    Throughout my life, I have had the opportunity to become pretty familiar with many instruments as a musician. I have been blessed to play with many different bands, as well as worship teams since junior high. I have come to be incredibly confident in my abilities with most instruments I have used. In my years of experience, I have come to realize that the acoustic guitar, over the electric guitar, is my favorite. I have played many instruments but I always seem to go back to the guitar. Mostly, I have always been led back to the acoustic. I feel the acoustic has such a wider range in sound, and can not only have an upbeat sound but can be played soft as well. Whether I am leading worship or singing my kids to bed, the acoustic is always the guitar I reach for.
