Physics is all around us, and yet we always overlook it. We see, hear or feel something happen but never stop to question why. Physics will tell us why. Music plays a part in everyone's lives. So much so that it is often overlooked and the technicalities of it are unappreciated. Sure there are times when we listen carefully to the music behind the songs we hear, we may focus on the rhythm or the harmonies, but we never think of what it took to make the sounds that we are hearing. In this paper, I will explain the physics musical instruments. I will describe and define sound in psychics terms and then describe how different instruments create their unique sounds.
There are so many different kinds of music, and thanks to the variety of instruments the combinations of sounds that we can make are limitless. Before we look at musical instruments we have to look at music itself. We need to know what it is made of and learn some basic terms.
In physics, music is essentially a form of energy and is transferred by a wave. There are two basic kinds of waves. The first is a transverse wave where the medium vibrates at a right angle up and down causing the wave to move to the right. A compressional wave (or longitudinal wave) moves to the right and left because the medium vibrates in the same direction. Sound waves take the form of compressional waves and are caused by vibrations. Sound waves are distinguished by their speed, pitch, loudness and quality (timbre) (Lapp, 2003).
There are a few parts of sounds waves that we should be familiar with to better be able to understand the physics of music. The crest is the highest point of a wave, while the trough is the lowest. The wavelength of a wave is the distance between two adjacent ...

The Physics of the Alto Saxophone Essay - The Alto Saxophone is a single-reed musical instrument that was invented in 1846 by Antoine-Joseph (Adolphe) Sax. Adolphe Sax was born on November 6, 1814 in Dinant, Belgium. During his childhood, he studied the clarinet and flute at Brussel’s Conservatory. His father was a renowned maker of musical instruments during that time. Since Adolphe grew up with his father making instruments and studying the clarinet and the flute, it was obvious that he would end up following in his father’s footsteps....   [tags: wind musical instruments]

Physics of the Theremin Musical Instrument Essay - The theremin is an electronic musical instrument that is played using electrical fields. When it was first introduced, people were shocked to see this instrument that could be played without even touching it. The theremin unsually is tuned so that it has a range of three and a half octaves. The theremin's operation is based on the theory of beat frequencies. Two antennas stick out on each side. Usually a vertical antenna is located on the right which controls the pitch. The closer the players hand is, the higher the pitch....   [tags: physics theremin] 781 words

Musical Instruments Essay - Musical Instruments A fairly old instrument that is still in use today is the theremin. It has a particular design that is different from any other instrument around and is played much more differently then other instruments in circulation today. The theremin is an electronic musical instrument that is played using electrical fields. When it was first introduced, society was shocked to see this instrument that could be played without even touching it. The theremin is tuned so that it has a range of three and a half octaves....   [tags: Music] 1577 words

Physics of Music Essay example - "He who understands nothing but chemistry does not truly understand chemistry either" Georg Christoph Lichtenberg (1742-1799) Music is not purely a form of art. There is a great deal of science that goes behind the production of beautiful musical sounds. In order to understand how music is possible, one must have an understanding of physics. Physics allows us to create musical instruments with different tone qualities and the ability to be played in a certain way to produce a specific pitch or note....   [tags: physics music sound] 866 words

Physics of the Violin Essay - "String instruments have been played for more than a thousand years. Performance on string instruments has reached a level today that cannot be improved upon, and the quality of instruments built nearly three centuries ago is maintained in the best instrument made today" (Allen, 1). "The violin is a wooden resonance box that amplifies the soundwaves from the vibrations of the strings stretched across it" (Mandy). The most material for the construct the violin is wood; maple used for the back, ribs, and neck) and spruce for the top....   [tags: physics music musical instrument violin]

Essay about Physics of Guitars - 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]

Physics of the Acoustic Guitar Essays - Stringed instruments are most likely the oldest type of musical instruments. The acoustic guitar has been around since the 1500's, and is the most common stringed instrument used today. The guitar is one of the most versatile instruments in existence, being used in virtually every style of music. It can produce a wide range of sounds depending upon the style of the guitar and the type of strings used on it. The two main styles of acoustic guitars are the nylon-stringed and the steel-stringed....   [tags: physics guitars] 1810 words

History of Physics Essay - History of Physics Physics began when man first started to study his surroundings. Early applications of physics include the invention of the wheel and of primitive weapons. The people who built Stone Henge had knowledge of physical mechanics in order to move the rocks and place them on top of each other. It was not until during the period of Greek culture that the first systematic treatment of physics started with the use of mechanics. Thales is often said to have been the first scientist, and the first Greek philosopher....   [tags: Science Scientific Physics Essays] 1319 words

Essay on Physics of Electric Guitars - Introduction More than any other instrument, the electric guitar has shaped and redefined music in the last century. Although popular culture did not pay much attention to it when it was first introduced in the 1930s, it has since become equated with the very essence of rock and roll music. On an international level, the electric guitar is by far "the most famous instrument to come out of the United States" (howstuffworks.com). Background Inventors have been playing with the idea of electrically powered musical instruments since the 1800s, but "the first attempts at an amplified instrument did not come until the development of electrical amplification by the radio industry in the 1...   [tags: physics electric guitar]

Physics of Music Essay example - Fluid Behaviors of Sound Waves Sound is capable of being produced only if a medium is present. By this, I mean that, for there to be sound, there must be air. For a sound wave to be emitted by an instrument and be received by a listener, the instrument must excite the air around it and propagate its energy through the air, in the form of compression/longitudinal waves. When received by the listener, the waves pulse the eardrums with the same varying frequencies as they were emitted. An instrument shakes to produce its tone In instruments, air is excited and set into oscillation by vibrations....   [tags: physics music sound] 1455 words
