Description
The string instrument is simple yet complex to play. You have to first tune the instrument so it’s pleasing to the ears and is actually, more importantly, the right note to play a song. The musician must pluck the string to make it vibrate and produce sound. But with the other hand, you have to hold down the string in a precise place in order to play the right note. When you hold the string down and pluck it, it will make the required note. By tightening the string, the initial note gets higher. When you loosen it, the note will be low. When you tighten it, the note gets higher and more crisp when you pluck it. What’s different about our guitar is that it has only one string, bound on screws on either side of the wood. The string is moderately tight and the notes are marked on the string instead of there being frets. A regular guitar has a body and neck. The body is hollow to amplify the sound.

E5 26.2 52.4 659.25

Single reeds mouthpieces create sound by vibrating a reed against the plastic shell. The reed is held at the bottom by a metal ligature. It then vibrates the sound throughout the pipe and changes pitch based off the holes that are covered.

The length of the clarinet can greatly change the sound as well. The longer the instrument the lower the pitch. So the holes help control the pitch by "controlling" the length of the clarinet. The most critical parts of the clarinet are the holes and mouth piece. The way we found where the holes should be is we found the wavelength and divided it by 4. The reason we h is because of how the wave travels from high pressure to low pressure. The reason our clarinet is not the same as a regular is because they are missing holes. In a real clarinet there are 3 extra holes(most of the time). The reason we couldn't replicate this is because it would've taken to longer sadly.
Chimes sound will vary based off their length. the length can change by its natural frequency. The natural frequency is the sound heard when the chime is hit. Calculations for chimes:
Raising the note by a half step(C into a C♯) multiplies the frequency 2^(1/12). To do that, you need to divide the length of the chime by 2^(1/24). Therefore, the lengths of the chimer were of the form 37.5*2(n/24) where n is an integer. 37.5 is the starting point we chose, and it is a G♯.
