Build a Band

Our group was tasked with designing a wind, string, and chimes instrument to create a band. Our process included finding the range of notes that we wanted to play and finding the right material, length, and width of our instruments.

For our Wind Instrument, we made a giant boom whacker. It has a stand that holds our eight giant pipes. When you hit the end of a pipe it vibrates and creates sound. The longer the pipe creates more reverberations and a lower note. We also found that the wider pipes and the ones made with black plastic vibrated easier creating a louder sound.

For our String instrument, we made harp. We looked at the frequencies that we needed to create our notes and divided by 4 to find our string length. Then, we created the frame and attached our stings and tuned them to the correct notes. It makes sound because of the vibrating sound coming from the string. It has a lower pitch when the string is longer and was louder when it hits its natural resonance.

For our chimes, We made a xylophone using metal rods. Each material has its own natural frequency based on its material and shape. We found the right lengths for the notes we wanted and created our instrument using a frame.
