Build a musical Band
For this project wee were asked to create a band with instruments we create. We had to build string, wind, and a percussion instrument. For our string instrument we made a guitar, we made a recorder for our wind instrument. We also made a chime for percussion instrument. Each of these instruments had to be able to make a full octave, C, D, E, F, and G. We had to find the different wave lengths to figure out how long the strings, chimes and recorder needed to be.
Content
amplitude- refers to the distance from the mid-point to the crrest of the wave
frequency- how often vibration occurs (frequency=wavelength*wavespeed)
hertz- the unit of frequency
wavelength- distance from the top of the crest to the next one
period - the time required
wave- a wiggle in space and time
transverse wave - motion at right angles to the direction in which a wave travels
longitudinal wave- the particles that move in the direction of the eave rather than moving at right angles
interference (constructive)- waves increased in amplitude
interference (destructive)- the crest of one wave simply fills in the trough of another
interference-adding two waves together
velocity- wave speed= wave length*frequency
compression-pushes together
rarefaction- pulls apart
wave speed- wave speed= wave length*frequency
crest- high points of a wave
trough- low points of a wave
frequency- how often vibration occurs (frequency=wavelength*wavespeed)

Overall, this project was great. But, like any group project we experienced some troubles. One problem we had was one of our group members would not contribute unless forced to because they would constantly get of task. But, we over came this problem by having them do at least a little bit of work, but then me and my other team mate would make up their work for them. Another problem was trying to find the right string length in guitar strings. At first I was going to build the string out of fishing wire, but then we found that there was an large amount of guitar strings, and instantly decided to use them. The struggle with this was finding a set of strings that were the right lengths. I would find string that was the right thickness but they were too short, then find ones that were too thick but also the right length. In the end I found a set of string that were exactly the right length. Butt though the tough times we worked well together. We had good time management skills. For instance we finished our instruments with time to spare so we could spend extra time on our google document to explain how our instruments work. In this project I learned that I can be efficient in my building skills if I really try to stay on task. Though I would have liked to have a better working guitar but I worked with the materials I had to build a string instrument with only things that were available to me.
