Summary

The appearance of sound wave changes when the pitch changes. This means that the waves become closer together (wavelength decreases) when the pitch is higher. When the waves are farther apart (larger wavelength) the pitch is lower. The louder the wave, the higher the amplitude. This means that the wave is higher and it lasts longer. The quieter that a sound is, the less amplitude the wave has and the shorter it lasts. 

The relationship between frequency and pitch is that the higher the frequency, the higher the pitch of the note, the lower that the frequency is the lower than the pitch of the note is. We already know that sound travels through the movement of molecules. If there are more vibrations occurring, they cause more molecules to hit each other at a faster time, influencing the pitch of the note.

Backward-Looking

What process did you go through to produce this piece?

To produce this piece, we followed the engineering design process. First, we learned about sound waves and how musical instruments produce noise. Next, we started brainstorming ideas for our instrument. Originally, we wanted to create a wind instrument, but ran out of time and decided to create a string instrument instead. After we decided what we wanted to make, we started creating our prototype. Next, we used Audacity to capture the sound waves and compare different pitches. Finally, we played a song with our instrument and recorded it to play to the class. Overall, this process was a great learning experience and helped me learn more about our sound unit.

Inward-Looking

How do you feel about this piece of work? What parts of it do you particularly like? Dislike? Why? What did/do you enjoy about this piece or work?

I feel that we worked hard on this piece of work, and put a lot of time and effort into completing it to the best of our ability. I enjoyed the fact that we had a lot of freedom while creating our instrument, and could be creative in the design process. There is nothing I disliked during this process, I feel that it was a great learning experience and very fun project. Overall, I really enjoyed working on this piece of work, and feel that this project was a success.

Outward-Looking

Did you do your work the way other people did theirs? In what ways did you do it differently? In what ways was your work or process similar?

Throughout this project, we had a lot of freedom and creativity. Our final result was different from other groups. We had the freedom to chose what kind of instrument we wanted to make, and what the final design would look like. However, the process of completing this assignment was similar, and each task was completed at similar rates. Thus, during this project, I feel that each group had a unique final design and implemented creativity for each instrument.

Forward-Looking

What would you change if you had a chance to do this piece over again?

If I had a chance to do this piece over again, there is not much I would change. I feel that our group put a lot of time and effort into this project, and completed it to the best of our ability. However, if we had a chance to change something, we would have focused on creating one instrument, because we had a wide variety of instruments, and did not focus on making just one work. Thus, there is not much we would change, but if we had the chance, we would focus on creating one instrument first.
