|
| created by vibratons that are felt by the inner part of the ear |
|
|
|
| push the surrounding air in different directions, creating waves of high pressure and low pressure |
|
|
|
| areas of increased pressure |
|
|
|
| areas of decreased pressure |
|
|
|
| measures the rate of sound wave vibrations per unit of time |
|
|
|
| includes one compression and one rarefaction |
|
|
|
| amount of time it takes to complete one cycle of a sound wave |
|
|
|
| refers to the number of complete vibrrations per second |
|
|
|
| measurement of a frequency |
|
|
|
| one cycle, or one oscillation per second |
|
|
|
| highness or lowness of a tone and is determined by the number of vibrations per second of sound |
|
|
|
| the first person to determine pitches based on ratios |
|
|
|
| the interval from one tone to another tone that is eight full notes above or below the original tone |
|
|
|
| in what type of music are instuments tuned to and “A” pitch |
|
|
|
| 12 evenly spaced pitches contained within and octave |
|
|
|
| tuning to equally spaced frequencies |
|
|
|
|
| attak, sustain, and decay |
|
| three stages of a the sound envelope |
|
|
|
| provides the initial resistance to the force of friction that begins the vibration |
|
|
|
| the sound of the initial resistance creates the… |
|
|
|
| when the particular sound of the tone is created by the instrument |
|
|
|
| when the vibration loses force and the amplitude decreases until the vibration stops |
|
|
|
| the loudness or softness of a sound |
|
|
|
| measures the rate of sound wave vibrations per unit of time |
|
|
|
| measure of the power of a sound wave as it moves through space |
|
|
|
| 2 properties that determine the loudness or softness of a sound |

|
|
|
| the unique combination of the fundamental frequency and harmonics that differentiates one sound from another |
|
|
|
| additional sound waves that occur simultaneouly with the fundamental pitch |
