I need to know how an acoustic guitar works....?

Question

I need to know how it's constructed, how the sounds are made, and what occurs to make frquencies change.
Any help will be great, but I'd like to be able to explain it in a few minutes, and thanks in advance!

Answer 2

You are asking a question that takes years of knowledge and volumes of reading but I'll try to make it simple...

An acoustic guitar reproduced sounds by amplifying the sound of a plucked string with the use of a soundbox. This soundbox is constructed using various materials and can be made in different shapes to enhance the vibration of the strings.

The top of a guitar, called the soundboard is largely responsible for the tone of the instrument. It has bracing on the underside that provides strength while at the same time coloring tone further. Too much bracing will impede vibration and make the guitar sound tinny and quiet while too little bracing in the wrong place will cause the guitar to self destruct.

The construction of the back and sides play a large part in volume and structural integrity. By using different materials the builder can temper the sound as desired and improve durability.

If you require an explanation of the relationship between notes and fretting etc. feel free to email me... I don't want to be accused of being too long-winded.

Answer 3

Start with learning about strings from the man who invented the modern Western scale....Pythagorus.

After learning that if you divide a string in half...you have an octave, and if you divide that octave in half you have a fifth....

Then you can learn about the well tempered scale (which is technically out of tune) created by JS Bach. From that you can learn about frets.

You take the distance from nut to bridge divide by a certain number take the remainder and that is the distance of the 1st fret. Then you repeat using first fret to bridge distance.

After that you can learn about the wood properties and acoustic properties of sound propagation through the acoustic guitar.

it's a far more complicated question than can be explained here.

Answer 4

The sound is made by the vibration of the strings, and the frequency changes when the string is made shorter or longer (by placing fingers down or picking them up). Shorter strings make high frequency sounds and Longer strings make lower sounds. Turning the tuning pegs has a similar effect. Loosing the strings works like lengthening it, it makes a lower sound.
