In this project we learned about the physics behinds sound and instruments. First, everyone built their own metallophone which is an instrument similar to a xylophone. Then, we got into groups of three and built another instrument that was more complicated and required more effort. For that, we chose to build a kalimba which is an instrument that originates in Africa and is also called a thumb piano. We made a simple tutorial video on how to build your own kalimba. You can watch it below.
