The highest frequency that humans can hear is approximately

20,000 Hz.

An ethnomusicologist is someone who

studies music in its cultural context

A vibrating object that produces sound can be a string

TRUE

Sound waves can travel in a vacuum

false

Music that describes nature or tells a story is known as

tonal music

The following happens when a composer shortens a musical idea by using only a part of it

Fragmentation

A device that displays the continuous plot of a wave is called

an oscilloscope

The primary orchestral instrumental pallete consists of

the strings, the woodwinds, the brass, and the percussion

Orchestration is the combination of a conductor's musical ideas with the composer's musical ideas

false

The frequency of waves is given in

Cycles per second. The term was common until the 70's when we started calling this a hertz. One Hertz is the same as one cycle per second or cps. 10,000 hertz was called 10 KHZ or 10K/cps.

Energy is required in order to produce any sound

true

In order from highest to lowest, the common clefs are:

Treble

Alto

Tenor

Bass

Systematic musicology is the approach to music study from a scientific or a philosophical perspective. This covers all of the other approaches of musicology.

The modern term Hertz means

cycles per second.

The law of motion that states that an object will maintain its straight line motion until acted upon by an unbalanced force is

Newtons first Law

If the wavelength of a wave decreases what happens to its frequency if the wave is traveling at the same velocity

If the wavelength decreases, then the frequency increases if the wave is traveling at the same velocity.

Middle C sits next to the

C# and B.

What is the wavelength of sound in the air at 20000 Hz

1.716cm

Sound wave deals with the volume of the sound

yes

What the name of the highest note in this example

The outer ear does what

The outer ear helps funnel sound (vibrations) into the inner ear, increasing the number of quieter things you can hear.
