For this project we had to design and build three instruments with which you can play the notes A, B, C, D, E, F, and G. Our instruments had to be a string instrument, one had to be a wind instriment, and one had to use chimes. We also could come up with a song that we could play with our instruments for extra credit.
For our string instrument, we created our a guitar. We cut up wood and gathered guitar strings of different widths so it could produce different notes. We then glued together our wood pieces which created our guitar shape. After tightening the strings, we put a wooden fret on our guitar so it could make every sound on the scale. For our wind instrument, we created our own chimes by emptying out soda cans and filling each one up a certain amount so it would make each note. We used an app that showed what letter was being played. Lastly, for our instrument that used air movement, we created our own flute by measuring out the distance of each whole so it would create certain notes. We then drilled wholes into a PVC pipe with those measurements to get our final result.
concepts:
Wavelength- distance from crest to crest which is measured in meters. Wavelength is found in all instruments.
Frequency- how often vibration occurs in hertz.
Amplitude- distance from midpoint to crest(or trough).
Wave speed = wave length x frequency
Notes are based on frequency and wavelength. The higher the note the smaller the wavelength. You can increase frequency by tying the sting to make it vibrate faster which results in a higher note or sound.

I really enjoyed this project because we could experience how to build instruments. I learned a few new key things. I figured out that you need to plan to make something before you start to build it. another thing i learned is to be exact. As a group we worked together really well. As a group we could have planned a little better on how to build the flute and other things.We also needed to be able to stay together a little better. Overall I really enjoyed this project.
