I collected four empty containers with lids.

Then I found four different objects that I thought would make interesting sounds inside my containers.

 

The objects were popcorn kernels, coffee beans, cereal and noodles.

 

I filled the containers and then put the lids back on.

After that, I decorated my instrument.

The pitch changes with the different height and width of each drum.

With the fat and short drums the pitch is lower.
