Part I. This project offers the option of describing a process that can be described with your senses. I, being big into music, am well aware how digital and analog music work. One big pet-peave I have with my guitar is when it comes out of tune, and chords sound bad when multiple strings are played together. The tuning process to make a guitar play a certain frequency is analog, as each knob on the head of the guitar (one for each string) is turned little by little until the correct frequency is reached. Since any frequecy (within reason) can be reached by tuning a guitar this way, it is clear that this process is analog.
Part II. To solve my live-threatening problem of having my guitar out of tune, I've thought of a process to turn this process digital. Instead of using the turning knob, and giving any frequency a possibility to be played, I would sample each frequency of a "perfect note". These perfect notes are the ideal pitches that a guitar is actually supposed to have. As an example, the common note "middle A" is 440 hertz. This also describes the quantization, where these individual values are assigned to each string.
The spacing of the frets on a guitar's neck is designed for the 6 strings to all be perfectly tuned, so wherever a note is played, it will have one of these "perfect frequencies", once again just pointing out there are discrete values for which notes can be played. The resolution part of this project really takes care of it self, as the soundwaves are produced at specific frequencies, therefor the resolution of each note is its pitch value, how ever many hertz the note is. The fidelity of this object is also quite simple, as the input frequency exactly matches the output sound that comes out of the instrument.
The picture I have here (sorry if its a little blurry) shows my theoretical model for how the new guitar neck would look, with little plus and minus buttons where the tuning knobs would be. These would adjust the notes of the string to a discrete model, where there would be a jump occuring (EX. 440 Hz on middle A to 466.2 Hz on an A-sharp, which is one half step up. Half steps are the standard musical increment.)
Part III. If this device was implemented, the entire music world would have to change to adjust to it. Not only would the guitars head have to change, but the string would probably also have to become digital, and maybe put buttons on every fret, kind of like the picture below, which depicts the most advance guitar from the popular game "rock band". Also, troubles could arise based on different temperatures or humidities, as those to factors effect the speed of sound, therefor also effect note frequencies. It would also take away the uniqueness of music, specifically rock music, as musicians could not implement there own subtle inperfections, or guitar tricks and maneuvers that only an analog guitar could perform. I am all for creativity and uniqueness, so I'm not sure this analog to digital conversion would be good for music as a whole, however, it would make tuning my instrument a little less of a hassle.
