One night the thoughts got the best of me, and I saw no end in feeling like this. I was having suicidal thoughts, I hated everything about myself, I didnt deserve love, I wanted to be around anyone. Things were a lot worse than I thought they were. I quickly started seeing a therapist, talking to er about everything I was feeling. I talked to on of the trainers at my school and she pointed me in the right direction. I thought the best thing I could do was to go back and see a therapist. I wasn't the same happy bubbly girl that I always was. I was angry all the time, I would cry at random, I would sit in my room all alone while everyone else was out doing fun things that I would usually partake in. I started to really pay attention to all my feelings. Not until then did I realized that I was presenting all the symptoms that I used to have when I was younger and was diagnosed with depression. Thankfully, I met my now girlfriend and she pointed out that I just seem down. I dread doing anything, I have no ambition to go to class, I don't even want to play soccer at this point, the one thing that always kept me afloat. Based on a large private collection of plucked stringed musical instruments (plus additional material from books and websites), this ATLAS will give you information about almost all the different plucked instruments still in use. A couple weeks go by and I see that I am in a complete slump. of lute, guitar, banjo and mandolin type. I figure its just all the early morning workouts and the long class days. I've been noticing that I just out of it. Things aren't as great as they were in the fall. The strummer excited fewer harmonics than the dulcimer did.Fast forward again to the spring season. The dulcimer has a peanut shape and is comparatively much larger than the strummer, which is triangular. The colored numbers indicate different body resonance frequencies and the percents represent the fraction of the sound that is due to the body resonance. The dulcimer and strummer have a wooden body, while the banjoвЂ™s body is a membrane. The following figures show the relations between the string and body resonances for the dulcimer, strummer and banjo that work together to form the unique sound of the instrument. The strummer data indicated that the notes excited with the thumb had a much larger correspondence with the body oscillations. For the mandolin and the acoustic guitar, the body oscillations only affected the fundamental harmonics. The body oscillations mainly affected the fundamental and second harmonics. The circular shaped banjo body excited the highest amount of harmonics, yielding its вЂњtinnyвЂќ sound. The figure eight and triangular shaped instruments produced a significantly larger amount of harmonics with the pick as compared to the peanut or teardrop shaped instruments. The results for the lesser-known instruments follow here. The instruments were separated into their corresponding body shapes to see the differences. To understand the differences amongst instruments, we correlated the string and body oscillations. These must keep the string fixed at the ends. A string fixed at both ends can oscillate in many modes, called harmonics. I tuned it's two strings in A octaves.Tools and materials I propose:Bandsaw. The parts of an instrument interact and force each other into vibrating at their harmonics (standing wave patterns). I made this instrument using an oven pan and spruce. The natural frequencies of a musical instrument are called the harmonics of the instrument. Musical instruments create sounds at their natural vibrational frequencies, which depend upon their size and structure. We performed comparisons of the instruments that revealed each instrumentвЂ™s unique characteristics. We also analyzed high-speed videos of the strings to better observe the oscillations produced. We studied body vibrations by looking at the sand patterns that form when the instrument is excited at different frequencies. In this research, we gathered string oscillation data, vibrating the strings at different locations with different methods of excitement. These elements interact to create the sound we hear in each instrument. Stringed instruments create the sound in three phases: (i) the source or string, (ii) the medium or body and (iii) the interface, which is the oscillation of the air around the body. We strived to understand how different stringed instruments function individually, and how instruments differ in their sound and function. Our objectives for this project include an in depth analysis of the properties of stringed instruments.
