Worksheet Overview

QUESTION 1 of 10

Pitch describes how high or low a sound is.

Recorder Saxophone
RECORDER SAXOPHONE

 

A recorder produces a higher-pitched sound than a saxophone. The pitch changes with the length of the tube of air which vibrates.

 

A short tube of air produces a high pitch. A long tube of air produces a low pitch.

  • Question 1

How high or low a sound is is called... 

CORRECT ANSWER
pitch
EDDIE SAYS
Yes, the pitch of a note determines whether it sounds high or low.
  • Question 2

Which TWO of these are low-pitched instruments?

CORRECT ANSWER
cello
bass drum
EDDIE SAYS
Both the cello and the bass drum produce low-pitched sounds, so they produce low notes. The whistle and recorder, on the other high, sound much squeakier as they produce high-pitched sounds.
  • Question 3

Which TWO instruments in this list are high-pitched instruments?

CORRECT ANSWER
piccolo
violin
EDDIE SAYS
Remember, high-pitched = high and squeaky sounds. So, in this list both the violin and the piccolo sound high when they are played. On the other hand, the trombone, the cello and the bass guitar are all great at producing low, boomy sounds.
  • Question 4

When musicians change the pitch of their instruments, they are...

CORRECT ANSWER
tuning
EDDIE SAYS
Musicians 'tune' their instruments to produce the correct pitch for each note.
  • Question 5

To tune a drum, what do we have to do to the skin? 

CORRECT ANSWER
stretch it
EDDIE SAYS
Stretching or relaxing the drum skin changes the pitch of the sound it makes. If we make it tighter, the pitch of the sound goes up. You can try it by pulling on an elastic band and then twanging it.
  • Question 6

To tune a guitar, we have to stretch or relax the... 

CORRECT ANSWER
strings
EDDIE SAYS
Guitars, violins, cellos and so on are stringed instruments and they are tuned by tightening or loosening the strings to make the note higher or lower respectively.
  • Question 7

Esther and Gabi fill three bottles with different amounts of water.

 

Bottle of water

 

Bottle 1 they fill nearly to the top.

Bottle 2 is half-full.

Bottle 3 is less than half full.

 

Esther blows across the top of the bottle to produce a sound.

Which bottle will produce a high-pitched sound?

CORRECT ANSWER
Bottle 1
EDDIE SAYS
The air in the bottle which is nearly full of water vibrates at a higher pitch because it has less space.
  • Question 8

Which bottle will produce the lowest pitch?

 

Bottle 1 - nearly full

Bottle 2 - half full

Bottle 3 - less than half full

CORRECT ANSWER
Bottle 3
EDDIE SAYS
A longer column of air makes a low-pitched sound because it vibrates more slowly.
  • Question 9

Esther and Gabi make sounds by twanging a ruler on the edge of a table.

 

They change the pitch by... 

CORRECT ANSWER
changing the length of the ruler over the table edge
EDDIE SAYS
The longer the piece of ruler vibrating, the lower the pitch.
  • Question 10

Gabi and Esther make their own 'panpipes' using jumbo drinking straws.

 

Straw whistle

 

What must they change to alter the pitch of the sounds?

CORRECT ANSWER
the length
EDDIE SAYS
The length of the straw changes the length of the vibrating column of air , which changes the pitch. These are great to make! Cut a drinking straw in half, cut one end to make a pointy shape, and try blowing down it gently. When you can make a brilliant squeaky sound, try cutting the straw shorter and blowing again. The pitch should go up!
