For this project each member of each group was assigned to create their own instrument, and each group had to have at least one of each of these types of instruments: Wind, string, and percussion. But we took it a step further and researched how each instrument worked. To do this we looked into waves, and more specifically, sound waves and how they worked. The instrument I created is the glass harp by filling a series of stemmed glasses varying in size and shape with different amounts of water to get each note, and you can play it by wetting your finger and rubbing it around the rim of each glass. It plays a beautiful and resonating sound that seems like it is coming from everywhere at once. Below is a picture of the glass harp I created for this project
My instrument creates sound because when you rub your wettened finger along the rim of the glass the roughness of your finger causes the glass to catch and get pulled along then released, making it vibrate back and forth. This sends sound waves through the air and to your ear which then converts it into signals that are sent to your brain.
Content:
Medium: A substance that lets an energy travel from one place to another
Wave Length: The distance from crest to crest in a wave
Crest: Highest point on a wave
Trough: Lowest point on a wave
Frequency: How many waves pass per second
Constructive Interference: When 2 waves collide and their sizes add
Destructive Interference: when 2 waves collide and their sizes subtract
Beats: when 2 sound waves of different frequencies hit your ear causing alternating constructive and destructive interference, making louder and quieter sounds
Conclusion:
All in all this project was really fun, I learned a lot about how waves work and got to create a really cool instrument in my opinion. My groups instruments all played a similar ghostly haunting style of music so they synergized well. I couldn't help my group out much because I was mainly stuck out in the hallway tuning each glass, I didn't have much chance to work on leadership either. I feel like even without much communication we still managed to stick to a similar theme and worked good together for the final presentation. One thing I wish happened was to have all the groups play songs but we ran out of time, but it was still a great project
