How does an acoustic and electric guitar work Please be specific

Answer 1

its doent, you work it

Answer 2

ACOUSTIC GUITAR:
***********************
When the strings on a guitar vibrate, they transmit their vibrations to the saddle.
The saddle transmits its vibrations to the soundboard.
The soundboard and body amplify the sound.
The sound comes out through the sound hole.
The particular shape and material of the sound board, along with the shape of the body and the fact that a guitar uses strings, give a guitar its distinctive "sound."
The body of most acoustic guitars has a "waist," or a narrowing. This narrowing happens to make it easy to rest the guitar on your knee. The two widenings are called bouts. The upper bout is where the neck connects, and the lower bout is where the bridge attaches.

The size and shape of the body and the bouts has a lot to do with the tone that a given guitar produces. Two guitars that have different body shapes and sizes will sound a bit different. The two bouts also affect the sound: If you drop a pick into the body of a guitar and rattle it back and forth in the lower bout and then the upper bout, you will be able to hear a difference. The lower bout accentuates lower tones and the upper bout accentuates higher tones.

The face of the neck, containing the frets, is called the fingerboard. The frets are metal pieces cut into the fingerboard at specific intervals. By pressing a string down onto a fret, you change the length of the string and therefore the tone it produces when it vibrates.
Between the neck and the head is a piece called the nut, which is grooved to accept the strings. From a musical standpoint, the saddle and the nut act as the two ends of the string. The distance between these two points is called the scale length of the guitar.

The strings pass over the nut and attach to tuning heads, which allow the player to increase or decrease the tension on the strings to tune them.

In the soundboard is a large hole called the sound hole. The hole is normally round and centered, but F-shaped pairs of holes, as in a violin, are sometimes seen. Attached to the soundboard is a piece called the bridge, which acts as the anchor for one end of the six strings. The bridge has a thin, hard piece embedded in it called the saddle, which is the part that the strings rest against.

When the strings vibrate, the vibrations travel through the saddle (the anchor for the strings) to the bridge to the soundboard. The entire soundboard is now vibrating. The body of the guitar forms a hollow soundbox that amplifies the vibrations of the soundboard.
If you touch a tuning fork to the bridge of a guitar you can prove that the vibrations of the soundboard are what produce the sound in an acoustic guitar.

ELECTRIC GUITAR
*************************
Some electric guitars have a hollow or semi-hollow body with the resonating cavity found in an acoustic guitar, but the most popular electric guitars have solid bodies. The sound is produced by magnetic pickups and controlled by several knobs. If you pluck a string on an electric guitar that is not plugged in, the sound is barely audible. Without a soundboard and a hollow body, there is nothing to amplify the string's vibrations.

Amps and Distortion:
Most electric guitars are completely passive. That is, they consume no power, and you don't have to plug them into a power supply. (Some do have "active" electronics powered by an onboard battery.) The vibration of the strings produces a signal in the pickup coil. That bare, unamplified signal is what comes out of the guitar and into the amp.
The amp's job is to take the guitar's signal and make it audible by boosting it enough to drive a speaker. The fascinating thing about an electric guitar amp is that the amp is actually a part of the instrument.

The role of an electric guitar amp is completely different from the amplifier in a stereo system. A stereo amp is meant to be transparent -- its job is to reproduce and amplify sound with as little distortion as possible. With an electric guitar amp, musicians often seek distortion as well as the option of a "clean" sound. Distortion results when the signal in an amp's circuitry is too powerful for that circuitry. The distortion is actually a part of the desired sound, and many amps are designed so that guitarists can control the level of distortion.

Musicians may also take advantage of feedback loops between the amp and the guitar. If the sound coming out of the amp and speaker is loud enough, it can cause the guitar's strings to vibrate. The musician can hit a note with the guitar, and the amp will cause that string to continue vibrating indefinitely. Both of these concepts -- amp distortion and feedback -- are unique to the electric guitar.

Answer 3

Acoustic guitar -- the body of the guitar is hollow and is designed to amplify and project the sound created when the player plucks or strums the strings.

Electric guitar -- the body of the guitar is usually solid and contains one or more "pickups" (which are basically glorified electromagnets) that pick up the vibrations of the strings and convert the frequencies into electrical energy. That electrical energy is carried by wires into an amplifier that converts the electrical energy back into sound energy through a speaker.

Answer 4

Guitar in general = sounds come from the vibrations of the strings. The guitar has 'frets', the little metal pieces on the neck, so you can make different notes up and down on each string, and play groups of notes called 'chords' (violins and cellos, same principle applies except they have no 'frets')

Acoustic = sounds amplified by hollow body of guitar
Electric= sounds captured and amplified electronically by pickups on the guitar, is a solid body

Answer 5

Guitars are obviously made up of wood and steel or nylon strings. When you pluck a string you are hearing the vibrations being enhanced by the hollow sound hole. A chord is just notes added together. The strings are held tight by the bridge (thing at the bottom of the guitar the strings connect to) and the tuning keys. It's like when you stretch a rubber band very far and someone plucks it.

Answer 6

the sound from acoustic guitars comes from the sound of the string vibrating, and echoing inside the body and coming out of the sound hole. The pitch of the string is effecting by how long the string is and how tight it is. Shorter/tighter is higher in pitch. The electric guitar is similar, except the vibrations are picked up by magnets in the body called pickups, and amplified by....well, an amplifier

Answer 7

Well, it's all about vibration. The electric guitars have pickups, since the body doesn't project vibration. You should research the overtone series, this is why the frets are in a particular distance from each other, etc.

Answer 8

im a intermediate guitar participant and that i come across guitar hero video games extra problematic than enjoying the actual guitar. for one, you have six strings on a guitar, the place by using fact the pastime has 5 buttons. the pastime extremely has you shifting your finger further once you play single notes than extremely enjoying actual guitar. the place a be conscious on a actual guitar could have you ever in basic terms fretting a decrease or higer string. the pastime makes you difficulty a button that further. i like enjoying chords on the pastime. in that, it does experience like your extremely enjoying chords. yet another element is which you dont incredibly could seem at a demonstrate whilst enjoying a actual guitar. so which you do desire extra hand eye cordination to play the pastime. the songs in the pastime are set up incredibly solid. its no longer in easy terms random button presses, the pastime does have repeatable varieties. its defintely relaxing. its in basic terms extra basic to play actual guitar.

Answer 9

based on precise calculations (phi) the guitar itself is designed to allow strings to vibrate waves both into the air and into the guitar (pickups to transducers or to resonate in the body of an acoustic)

Answer 10

Vibrations from strumming the strings, amplified in the electric. Like pulling on an elastic band....

Answer 11

the structure of the guitar allows enough pressue to have the strings tense so they will vibrate good. think about the strings, on aN ACOUSTIC. AND DONT FORGET TO LISTEN TO OTHER PLAYEERS.
