Lesson Two Review Questions

Question 0

Define amplitude

Answer 0

Amplitude means loudness of volume. Amplitude is controlled by how far each air molecule is displaced. In acoustics, scientists measure amplitude in decibels

Question 1

Define frequency

Answer 1

Frequency is an accurate term for all sounds (definite or indefinite pitch). Which is made up of physical vibrations of air molecules. A particular pitch will be determined by the speed if the vibrational pattern

Question 2

Define timbre.

Answer 2

Timbre is derived from a French word that means “tone-color.” Timbre is the quality of a sound that distinguishes it from other sounds or distinctive tones of the same pitch and volume. All instruments that produce a sound are a composite of the fundamental pitch and its overtones. Timbre is determined by emphasizing certain overtones and suppressing others, due to the instrument configuration, materials, size, and the way the sound is produced

Question 3

Name the four instrumental families of the modern orchestra and the ways they produce sound.

Answer 3

The instrument families are the strings, woodwinds, brass, and percussion.

Question 4

Strings

Answer 4

Draw a bow across or pluck strings that resonate and are amplified by the body of the instrument

Question 5

Woodwinds

Answer 5

Sound comes by blowing air into them, covering hikes to change the length of the air column (for pitch change)

Question 6

Brass

Answer 6

Long and tubular and de the buzzing motion of the lips in a mouthpiece, and pressing a valve to hangs the lefty of the air column

Question 7

Percussion instruments

Answer 7

Any sound source that is struck to produce a sound (shaking counts too). Piano and harpsichord share their identity with both strings and percussion families since they are both struck and have strings
