How to make musical instruments.
Questions and Answers
- 1.
What makes a sound?
- A.
Changing how hard you hit something
- B.
The changing of the size of a string
- C.
The vibration of something to move air
Correct Answer
C. The vibration of something to move airExplanation
Sound is produced when an object vibrates, causing the surrounding air particles to vibrate as well. This vibration creates a disturbance in the air, which is then transmitted as sound waves. Therefore, the correct answer is "the vibration of something to move air".Rate this question:

What changes the pitch of a wire?
- A.
Its thickness
- B.
Its length
- C.
How hard you are plucking it
- D.
How tight it is
Correct Answer(s)
A. Its thickness
B. Its length
D. How tight it isExplanation
The pitch of a wire is determined by its thickness, length, and how tight it is. Thicker wires produce lower pitches, while thinner wires produce higher pitches. Longer wires also produce lower pitches, while shorter wires produce higher pitches. Additionally, the tightness of the wire affects the pitch, with tighter wires producing higher pitches and looser wires producing lower pitches.Rate this question:

How is a drum made?
- A.
By stretching some material over a container
- B.
Stretching a string between two nails
- C.
Blowing over a bottle
Correct Answer
A. By stretching some material over a containerExplanation
A drum is made by stretching some material over a container. This is typically done by using a cylindrical or round-shaped container, such as a wooden or metal frame, and then stretching a material, such as animal skin or synthetic material, tightly over the top of the container. This creates a resonating surface that can be struck or tapped to produce sound. The tension of the material determines the pitch and tone of the drum.Rate this question:

How can you make a sound with a bottle?
- A.
Plucking it
- B.
Blowing over it
Correct Answer
B. Blowing over itExplanation
Blowing over a bottle can create a sound because when air is blown over the opening of the bottle, it causes the air inside to vibrate. This vibration produces sound waves that we can hear. The pitch and tone of the sound can be altered by changing the amount of air blown or the size of the bottle opening. Plucking a bottle, on the other hand, does not typically produce a sound unless it is made of a material that can vibrate audibly when plucked.Rate this question:

How can you change the pitch of a bottle?
- A.
Making it tighter
- B.
Hitting it louder
- C.
Varying the amount of water in it
Correct Answer
C. Varying the amount of water in itExplanation
By varying the amount of water in a bottle, the pitch can be changed. This is because the pitch of a sound is determined by the frequency of the vibrations produced. When water is added or removed from the bottle, it affects the volume of air inside, changing the resonance and thus altering the frequency of the sound produced. Therefore, adjusting the amount of water in the bottle allows for control over the pitch.Rate this question:

What does it mean to amplify something?
- A.
Changing the pitch
- B.
Changing the height
- C.
Changing the volume
Correct Answer
C. Changing the volumeExplanation
Amplifying something means increasing its volume. When something is amplified, the volume is raised, making it louder or more intense. This can be done with various devices such as amplifiers or speakers. Changing the pitch refers to altering the frequency of a sound, while changing the height is unrelated to the concept of amplification.Rate this question:

What is this acoustic guitar using to amplify itself?
- A.
The strings
- B.
The hollow body
- C.
Pegs
Correct Answer
B. The hollow bodyExplanation
The correct answer is the hollow body. Acoustic guitars use the hollow body to amplify the sound produced by the strings. As the strings vibrate, the sound waves resonate within the hollow body, creating a louder and richer sound. The shape and size of the hollow body also play a crucial role in determining the tone and projection of the guitar.Rate this question:

What does resonance mean?
- A.
Letting something vibrate without touching it
- B.
Letting sound bounce back and fourth inside of something
- C.
Pulling something really hard
Correct Answer
B. Letting sound bounce back and fourth inside of somethingExplanation
Resonance refers to the phenomenon of sound waves bouncing back and forth inside an object or medium. When an object is able to vibrate at its natural frequency due to the presence of an external force, it creates a resonance effect. This can result in amplification of sound or a sustained vibration. Therefore, the answer "letting sound bounce back and forth inside of something" accurately describes the concept of resonance.Rate this question:

How are different pitches created with this instrument?
- A.
Changing the length of the string
- B.
Changing how hard you pull the string
- C.
The hollow body
Correct Answer
A. Changing the length of the stringExplanation
Different pitches are created with this instrument by changing the length of the string. When the length of the string is altered, it affects the frequency of the vibrations produced, resulting in a higher or lower pitch. By adjusting the length of the string, musicians can play different notes and create a range of pitches on the instrument.Rate this question:

What was the main point of this passage?
- A.
To look at different instruments
- B.
To look at how instruments make sound
- C.
To look at how instruments change their volume
Correct Answer
B. To look at how instruments make soundExplanation
The main point of this passage is to examine how instruments produce sound. The passage likely provides information and examples about the various mechanisms and techniques used by different instruments to create sound. It may discuss the role of vibrations, air pressure, strings, or other factors in generating sound in instruments. The passage is focused on exploring the process of sound production in instruments rather than simply observing or comparing different instruments.Rate this question:
