Document Summary
Certain scientists believe that we are hard-wired to not just to hear music, but also to feel a significant emotional connection to it. Levitin also argues that human identity has music at its core, and that common themes in music include love, friendship, knowledge, religion, relationships, and joy. Function of the ear: is to gather sound waves. The function of hearing: is to extract some sort of meaning from those sound waves. The ear detects sound waves and transforms the info into neural signals. Sound waves are simply changes in the mechanical pressure transmitted through solids, liquids, or gases. Sound waves have two important characteristics: frequency and amplitude: frequency: refers to wavelength and measured in hertz (hz), the number of cycles a sound wave travels per second, pitch: the perceptual experience of sound wave frequencies. High-frequency sounds (tires screeching) have short wavelengths and a high pitch.
