Sound is longitudinal wave produced by compression and rarefaction of matter. Sound is produced when a vibrating source creates rhythmic variations in the air pressure (zitzewits & Murphy, page 268) to determine the wavelength of sound you need an equation which is, v=fλ. To explain this equation in broken down context v=velocity (m/s), f= Hertz(Hz) and the symbol λ(Lander) is the unknown that needs to be solved in order to determine the wavelength.
Physics of the guitar
The guitar has been around for thousands of years in one form or another. It is believed that the first forms of guitars were used in Egypt 3000 years ago. The guitar usually has six strings tied tight around a hollow body to resonate the sound. A guitar is a chordophones; chordophones is an instrument in which its standing wave is initially created in the strings of the instruments (David R. Lapp, page 25). The sound that produces from the guitar strings being plucked or strummed vibrate from the circle opening below the strings and resonate through the guitar till the wavelength eventually fades out, strings and gu...
Electric guitars are devices that generate sound from a set of pickups that convert string vibration into electrical signals for amplification. The sound starts out as vibrations the musician creates while playing. These vibrations are picked up by the pickups of the guitar. What are pickups? Pickups are permanent magnets wrapped around in a coil. Since the strings are made with a special material called ferromagnetic, they interact with the magnetic fields in the pickups and force electrons to move in the loop. Moving electrons can generate a signal that can be read by the amplifier.
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. A horizontal loop antenna is located on the left and controls the volume. The closer the hand is, the louder the volume.
Now a days, guitars are seen and heard everywhere. There are so many different types and styles. The two major categories are electric and acoustic. Electric guitars where first introduced in the 1940’s to enhance and amplify the sound of acoustic guitars. Acoustic guitars have hollow, wooden bodies. When the strings are played, the sound is amplified and echoes in the resonating body (New Grove 827).
The guitar consists of four to eighteen strings. The sound of a guitar is projected through electrical or acoustic amplification. It is played by plucking or strumming the strings using the right hand while fretting the strings with the left hand.
The guitar is a musical instrument that is played by the plucking or strumming of its strings. According to the records, this instrument was invented in Spain in the 15th century. The guitar’s appearance has changed since then. The body of the guitar was narrower than what it is now. Guitars were considered “lutes” at the time. In which lutes formed to be vihuelas then later became guitars. When the guitar was first invented, it only had four-strings so it was called a four-course guitar. However, it has a variety course of strings now. The guitar is one of the instruments that has a major role in music, today. The genres of music that
Guitars and ukuleles were originated from different places at different times. The guitar originated from Malaga, Spain in the fifteenth century. It was engineered by a spanish black man, the first guitar was originally a four stringed guitar. By the time the guitar went through the classical period, and after the guitar was made a six string, also known as a modern day guitar. The ukulele is originally
The vibration of the strings of a guitar causes the sound wave, but is not actually what you are hearing. The amplification of the sound wave is what is actually heard. The differences in the tension of the stings and the mass of the strings affect the pitch of the sound produced. The ends of each string are nodes, or where the wave does not travel from its initial position. The note you hear from the string is actually the first harmonic of the wave; other harmonics created when plucking a string form the undertones and overtones of a note. The waves on a guitar string are transverse waves, meaning they travel perpendicular to the original position. The waves are also standing waves, because they remain in the same position.
Aptly named the Rock & Roll Generation, the 1950's saw the birth and rise to prominence of rock-n-roll and rockabilly (an early style of rock-n-roll). However, this musical revolution would never have been possible without the invention of the electric guitar by Les Paul in 1952 (1). The solid-body electric guitar produced a distinct sound unlike any other instrument during that time; as a result, it was this unique sound that rock-n-roll music developed its entire foundation upon. Today, Les Paul’s guitar (now owned by the popular guitar company Gibson) remains one of the most famous electric guitars not just in the America, but also in the world, along with the Fender Stratocaster and Telecaster. With the advent of the electric guitar, Carl Perkins was a pioneer in the establishment of rock music, and his particular ...
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.
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 electric guitar has greatly impacted how music was played in the past, the present, or the future. Players can be creative and achieve a great sound from the wide variety of guitars, pickups, pedals, or amps. Whatever type of music you enjoy, everyone should appreciate the importance of the electric guitar.
Each of the senses receives a different stimulus that allows us to perceive that specific type of information. For hearing the stimulus is sound waves. These are waves of pressure that are conducted through a medium (Martini, 2009). Often this medium is air but it can also be water or a solid object. Each wave consists of a region where the air molecules are gathered together and an opposite region where they are farther apart (Martini, 2009). A wavelength is the distance between either two wave peaks or two wave troughs. The number of waves that pass through a fixed reference point in a given time is the frequency. High pitch sounds have a high frequency where as low pitch sounds have a low frequency (Myers, 2010). The amplitude is the amount of energy, or intensity, in a sound wave. The more energy that a sound wave has, the louder it seems. For us to perceive any of the sound waves around us, they must pass through the external, middle, and inner ea...
Reason to listen: The guitar is an instrument that can be heard in all types of music, it would be nice to know some information about the guitar.
It was in eighth grade when my father made me started to listen to Johnny Cash. His music was old at my age, but his guitar made me fall in love with his music. It was right then that I decided to play the guitar, both acoustic and electric. When I got my first guitar, the new smell of wood spread across my room as I opened my guitar case. I could barely lift up my first time. My little body was covered by the size of the guitar. The strings felt thin on my little hands and my ears were filled with magic when I played it. With time I discovered that the guitar opened new things into my world. This instrument has dominated the way we make and listen to music. The guitar is one of the most versatile instruments in
Sound is essentially a wave produced by a vibrating source. This compression and rarefaction of matter will transfer to the surrounding particles, for instance air molecules. Rhythmic variations in air pressure are therefore created which are detected by the ear and perceived as sound. The frequency of a sound wave is the number of these oscillations that passes through a given point each second. It is the compression of the medium particles that actually constitute a sound wave, and which classifies it as longitudinal. As opposed to transverse waves (eg. light waves), in which case the particles move perpendicular to the direction of the wave movement, the medium particles are moving in the same or opposite direction as the wave (Russell, D. A., 1998).
