what I learnt about Pitch and Sound.

Pitch is a low sound wave and a high pitch is a high sound wave.

Frequency is a low or high sound wave a low one look's Wide and a high sound wave look's tall and lots of waves.

For this we used a computer program to get the sound waves we had to match them up to the right sound.

I learnt that you cant talk into a vacuum and you can talk through metal.
