The Physics of Music Essay examples

understand the invisible connection that so many of us feel towards music one must first understand at least the basics of music theory. How is it that a combination of pitch all caused by synthetic or

The vocal note produced by the vibrations of the vocal folds is complex and made up of periodic (regular and repetitive) and aperiodic (irregular and non-repetitive) sound waves. The aperiodic waves are random noise introduced into the vocal signal owing to irregular or asymmetric adduction (closing) of the vocal folds. Noise impairs the clarity of the vocal note and too much noise is perceived as hoarseness.

When I think about pitch the first things come to mind are instruments. This reminds me in middle school if you wanted to a part of the band, you got to test each instrument. I always had a fascinating with a flute, which had high a frequency and high pitch. Another instrument was a trombone; this had a low frequency and low pitch. This helped me understand the difference between pitches.

Heat: The amount of energy associated with the movement of atoms and molecules in matter.

After the positions were recorded for frequencies 1,803 Hz, 2,402 Hz, 3,002 Hz, 3,600 Hz, and 4,201 Hz, the wavelength was determined for each. This was done by subtracting the initial position from the final position (position final–position initial=wavelength). Using the calculated wavelength, the speed of sound in air at each frequency was determined by multiplying the wavelength by the frequency (speed of sound=wavelength x frequency). By adding the five speed values and dividing by the number of speeds, the average speed of sound was calculated. Then 344 m/s was used as the accepted

FREQUENCY:Frequency of a signal can be defined as the total number of cycles completed in one second . It is measured in Hertz.

* Tone – the duration (length), frequency (pitch), amplitude (loudness), timbre (quality of sound). * All sounds have the potential to be tones

power to evoke the sound it conveys. This is true of one of the many

Musicians know that all vibrating objects make sounds. Frequency measure how many times a string vibrates up and down. If a musician changed the length of the string, it also changed the frequency. High frequency will always equal a high pitch. When an octave is increased the frequency will double. Pythagoras discovered different sounds could be made with different weight and vibrations. Due this discovery, they also realized pitch could be controlled by the length of the string.

For example the Armenian ,Medieval period pieces were mostly low pitched and slow because they were supposed to make you feel sad and feel bad in a way they were slow pieces that did not have fast paces notes that made you feel excited and happy they were pieces that made you feel down and sad. I really enjoyed listening to Alexander Konstantinovich musical pieces because most of what was played was high pitched and fast paced, me personally I enjoy that a bit more then low pitched and slow they are fast and fun. For example land of heroes was a high pitched fast piece because it makes you think of people winning a war and there are the heroes of the land so it gives you an exciting good feeling of accomplishment, where the Armenian chants were from the medieval times and were made of more low pitches notes and gave you a feeling of sadness.

Tone colour is distinctly secondary to other musical elements. Greater variety of tone colour and more rapid changes of colour.

It is within this framework that I consider important to study the way in which sound is

Music dates right back to the prehistoric eras where primitive instruments were constructed using items like bone and wood. These primitive musicians would not have known many of the modern terms such as octaves

Frequency/Pitch: Bluetooth has a frequency in the 2.4 Gigahertz (2400 Hz) range. Bluetooth is often mistaken as the same as Wi-fi because they are both wireless, but Bluetooth is different as it runs on a lower frequency than Wi-fi. (Miller, A.B. 2001)

There are no definite forms of energy since possibilities of new forms of energy are limitless. However, the various forms of energy in physical science include thermal, chemical, electric, radiant, nuclear, magnetic, elastic, sound, mechanical, and luminous energies (Foland 13). Thermal energy or heat is the energy in random motion of particles. Chemical energy refers to the energy from the aggregate of positioning of electrons and protons. Radiant energy is the energy of electromagnetic radiation while nuclear energy and electric potential energy is energy emanating from nuclear fission and electrical processes respectively. Sound is a form of mechanical vibration, which propagates through any mechanical medium. It is closely related to the ability of the human ear to perceive noise.
