2. Pitch it High or Pitch it Low?
This game is called
Pitch it High or Pitch it Low?

3. Look at the picture on each slide and decide if the note shown by the arrow would be high or low.
If you think it is a high note, stretch your hand up high into the air and sing “High” in a high pitched voice
If you think it is a low note, push your hand down low to the ground and sing “Low” in a low (deep) voice
Which is it?
This note is high because the bar is short

4. This note is low because the bar is long
Xylophone

5. Panpipes are played by blowing air across the top of the wooden tubes
This note is high because the pipe is short

6. This note is low because the drum is big

7. A harp is played by plucking the strings
This note is low because the string is long

8. These brass instruments are called tubas. They come in different sizes
These brass instruments are called tubas. They come in different sizes. Some can play lower notes and some play a bit higher.
This tuba plays higher notes because it is smaller

9. A violin is played either by plucking the string or by pulling the hairs of a bow across the string to make it vibrate
This string plays higher notes because it is thinner

10. Organ pipes make a very loud sound when air is pushed through them by a large air pump called the bellows.
This pipe plays a very low note because it is huge

11. Glass bottles make a lovely sound when you tap them gently with a metal or wooden stick. You can change the note by putting different amounts of water inside the bottle.
The water changes the size of the column of air inside the bottle. An empty bottle has a long column of air to vibrate which gives a low note.
The bottle shown by the arrow has a lot of water inside. Because of this, it has only a short column of air inside, so this bottle will give a high note.

12. This tube is long so it will make a low note when struck

13. This bell rings with a higher pitch than the others because it is the smallest

14. Recorders come in a whole family of sizes
This recorder plays lower notes because it is bigger

15. End of game! How did you do?
Let’s recap on everything we know about pitch

16. Decide which description of an object or instrument makes a high pitched note and which makes a low note in each pair

22. Remember there are 3 things that affect the pitch of a note:
The length of the thing that is vibrating
The size of the thing that is vibrating
The tightness of the thing that is vibrating e.g. a string or drum skin
