As the centuries have passed, the concept of music has largely remained a part of social and economic interactions within human culture. Of all the contributing instruments, the guitar is one of the most complex and most used in all musical genres. There are documents that suggest that the guitar was played as far back as Babylonian times (Findlay 3). That said, the guitar is also one of the most elaborate instruments to build, with the greatest number of factors and variables involved in the construction. The most important variable is the materials chosen to make the instrument. Contrary to popular belief, the quality of the materials used to build a guitar greatly affects its sound. The topic of materials and components has been the subject of debate among stringed instrument enthusiasts and luthiers for decades. The driving force that allows materials to influence the guitar's resonance so immensely is the guitar's design; allows the physics of the sound to create most of the instrument's natural tone. It seems that simply picking and choosing the most expensive parts of a guitar will result in the most expensive sounding guitar, although that statement is somewhat incorrect. The prerequisite information that goes into building a top string instrument is an understanding of the physics of sound, rather than simply a fat wallet. First we need to ask ourselves: “What is sound?” Sound is a vibration that propagates as a mechanical wave of pressure and displacement through a medium. For most purposes, wood and air are the primary mediums of a guitar (Hokin 1). Simply, sound is a wave that pushes (compression) and expands (rarefaction) the molecules around it. Each wave is different in shape and length, and therefore produces a different tone....... half of the paper... but proves inconclusive (Lamb par 2). The problem is that while you try to isolate one variable of the guitar's aesthetics, all other variables are ignored and behave differently than normal. What type of wood did you use? Did he use maple, alder, spruce, basswood or something else? All the woods may have given different results. What type of pickups, strings, neck or bridge was used? It is comparable to the Heisenberg Uncertainty Principle in Atomic Theory; you can know the position of an electron, but never its speed, or vice versa. This is why building a guitar is such a trouble-shooting craft; no single part will make a difference, rather it is the relationship between all the parts that come together to create the voice of the instrument. That's why the quality of all components, and not the price of a component, affects the music of a guitar immeasurably..
