Instrumental Band
Project Description: The goal for my team was to build a band by constructing string, chime and wind instruments. However, our group built two wind instruments because the team had four members. The first wind instrument was a trumpet made of PVC pipe with 6 holes. The second wind instrument was a slide flute, also made from PVC pipe, but with a mouthpiece to create pressure and a slide inside the flute to create the different pitches. Next, we created a chime instrument by suspending different length metal pipes that when struck create sound from the natural frequency of the metal. Finally, we fashioned a guitar from wood using fishing wire as the strings and screws as the tuning pegs. The strings ran from the top of the instrument down the neck of the guitar to the base where they stretched across a hole called the resonator, which amplifies the sound the strings make when being plucked.

Concept: Definition, Equation, Variable, Unit, Notes, Relation to Project. (Not all included for each concept)
Transverse Waves: A wave where the particle movement is perpendicular to the wave movement, can travel through space, on electromagnetic spectrum, an example is light, we did several experiments with transverse waves involving the movement of slinkies as a model.
Longitudinal Waves: A wave where particle movement is parallel to wave movement, requires a medium to pass through, an example is sound, the purpose of this project was to create a device that could create different longitudinal waves.
Wave Speed: The velocity of a wave, v=(Greek letter lambda)f, v= velocity, measured in m/s= meters per second, sound travels at 340 meters per second through air, wave speed was featured in our equations when solving for other note components such as the frequency.
Wave Length: The distance from crest to crest of one wave, (Greek letter lambda)= v/f, (Greek letter lambda)=wave length, measured in m= meters, during our project in order to find the distance of the frets from the resonator we divide the wavelength of that particular note by two.
Frequency: Number of waves per second, f=v/(Greek letter lambda), f=frequency, measured in Hertz/Hz=waves/seconds, frequency is inversely proportional to the period, we had to determine the frequency for every note played.
Period: Time for one wave, T=1/f or f=1/T, measured in s=seconds, period is inversely proportional to the frequency, for some of our notes we used the period to find the frequency.
Amplitude: The height or magnitude of a wave, meters for transverse, pascals for pressure, amplitude controls volume, we measured amplitude during our slinky experiment.
Reflection:
When working as a team our group had pits and peaks. We did not collaborate or communicate well but we had great organization and were very efficient. When working on this project we each worked on our separate instruments and did not consult each other, which made some of our instruments lackluster. Our communication was also a weak point. In one instance I used the notes for the wind instrument when making the guitar and had to start over once I finally found out. However, our organization was second to none. We had developed a schedule for completing our project and had our own storage spaces for our instruments. Our efficiency while working was amazing, we were able to each create our own instruments without the help of others. Although we had lacking team dynamic we were able to complete the project as individuals.
