Project over view
For this project we were tasked with making musical instruments. We had to tune our instruments to a full octave, C, D, E, F, G, A, B. We also had to make three individual instruments; a string instrument, wind instrument, and precaution instrument. For our string instrument we made a guitar. For our wind interment we made a recorder. Lastly for our precaution instrument we made chimes.
How our instruments work
Concepts
Wave Length |
Amplitude |
Distance from one crest to next crest
|
Height of wave
|
Frequency |
Period |
How often waves come
|
How long a wave lasts
|
Velocity |
How we hear music |
Rate at which wave travels
|
Vibrations go into the ear drum and turned into words in our brain
|
String Instruments |
Wind Instruments |
The string is what vibrates
|
The air is what is vibrating
|
Percussion Instruments |
Hertz |
The object is contacting another object which is vibrating.
|
The unit used for frequency
|
Transverse Wave |
Interference -constructive |
A wave vibrating at right angles to the direction of its propagation
|
Waves move toward each other then double in size when together and then continue with the increased size.
Interference -destructiveWaves move towards each other and when hit one another and they are completely flat then continue through at same original size.
CompressionPushes wave together

Longitudinal WaveA wave vibrating in the direction of propagation.
CrestHigh part of wave
TroughLow part of wave

Rarefaction
Pushes waves apart
Reflection
Overall I felt this project went really well. Our group worked well together. We were always on task and didn't get mad at each other. I think we worked well together because we all chose one instrument and did it without the other people to interfere. A high in this project was when we all finished on time and were even able to decorate our instruments. I felt that it showed just how timely we had gotten everything done. There wasn't really any low parts of this project. If I had to choose a hard part it would have been when we didn't finish our google document, of how out instruments worked, right away. This was because it took some further research. Overall this was a nice easy project with a good group.
