Drum Size and Pitch
Is bigger better when it comes to making a smashing piece of music? See whether having a larger surface to pound changes the pitch that you create.
- Clear packing tape
- Small, medium, and large metal cans
- Can opener
- Quilt batting
- First, you’ll need three differently sized cans to create your music. Ask an adult to help you cut the ends of the cans and wash the insides. Make sure that there are no rough edges that could damage the surface of your drum.
- Now, let’s create those drums! Stand each can so that the hole you made sticks straight up. This end will act as the the opening for your drum.
- Beginning with the smallest can, attach a piece of clear packing tape to one side of the opening and stretch the tape across the opening.
- Secure the tape on the other side.
- Continue to do this until the entire opening of the can is covered in a layer of tight packing tape.
- Secure the ends of the tape by stretching a long piece of packing tape around the diameter of the can.
- Do the same thing with all three cans. Soon, you’ll have three drums to play!
- Now it’s time to create your mallet. You want your mallet to be something that’s easy to pound with but won’t hurt your drum’s surface. Take a pencil and wrap it in a handful of quilt batting.
- Use the packing tape to wrap the batting around the pencil. Make sure that all of the batting is covered in a layer of packing tape.
- Using your mallet, bang each drum in turn. Which drum makes the highest pitch? Which one makes the lowest? If there is a difference, and if so, why?
The larger the diameter of the drum, the lower the pitch of the drum.
