Why If you very lightly touch a guitar string at its midpoint you can hear an octave one above the fundamental string?
There is a very simple reason for this, This is actually a deliberate technique known as harmonics/ overtones. When a guitar string is plucked, the string vibrates at several frequencies. The vibration along the entire length of the string is known as the fundamental, while vibrations occurring between points along the string (known as nodes) are referred to as overtones. The fundamental and overtones, when sounded together, are perceived by the listener as a single tone, though the relative prominence of the frequencies varies among instruments, and contribute to its timbre. Harmonics are produced on the guitar by lightly touching a string, rather than fretting it, at any of these nodal points. When sounded the string can no longer vibrate at its fundamental tone; instead it is forced to vibrate at the specific overtones that correspond to the nodal point, resulting in a chime-like tone.
How is the higher note produced on a single string of a stringed instrument?
A higher pitch or note is produced by either shortening the string length by fingering (as in a guitar or violin), or by tightening the string, as in tuning a guitar. Higher pitches can also be played by lightly touching a string at its exact midpoint while plucking it, which suppress is fundamental pitch will allowing its harmonic to sound. This would produce a sound one octave higher.
What is an overtone in music?
I'll give as brief and basic an idea as I can. Consider something that produces musical sounds. There would be a vibrating string or wire, as for violins, other instruments in the string family, and pianos, or a column of air as for woodwinds and brass. The idea holds for the membranes of tuned timpani as well. A length of wire vibrates in some complex ways; it doesn't vibrate in one simple motion. It's easy to think of a tightened wire going up and down in the middle, uniformly, with no other motion involved. But it is more complicated than that. The wire will also vibrate as two halves. The left half will be 'up' while the right half is 'down', and so forth. Each of these halves will also vibrate by halves. The wire also vibrates in thirds of its length, and in fifths of its length, etc. The fundamental tone produced by the wire (the largest and simplest vibration) is the dominant tone, and it is this vibration that gives the tone its pitch name. But all the other vibrations produce pitches too, and while they are usually much softer than the fundamental tone, you can train yourself to hear them. Piano tuners use these overtones, also called harmonics, to help them tune accurately.
How is sound produced on a grand piano?
There is at least one string, a hammer (which is actually a very light piece of wood) and a damper corresponding to every one of the 88 keys of a piano. When a key is pressed, the corresponding damper moves away from the corresponding string(s) while the corresponding hammer strikes the string(s). When the key is released, the damper contacts the string(s), and it/they stop(s) vibrating (unless the sustain pedal, which moves all dampers away from all strings, is pressed). The harder or softer a piano key is pressed, the louder or softer the resulting tone is, which is why the instrument was originally called a "piano forte", Italian for "soft loud".
What is the reason that instruments make sound?
Sound itself is vibrations in the air that are perceived as sound by the ear. Instruments are created as vehicles for the generation and amplification of those vibrations. When one hits a drum, the head of the drum vibrates, causing vibrations in the air that are perceived by the ear as sound. If you place your hand on the drumhead to stop the vibrations, the sound stops. When one plays a trombone, his lips buzz (vibrate) into the mouthpiece and that sound is amplified by resonance within the instrument. When a guitar string is plucked, the vibration of the string causes vibrations in the air that are perceived as sound.

Which type of musical instrument produced music by amplifying the vibration of attached cords?
Drums, Guitars, Harps and other instruments with strings.
How would you explain an individual particle with string theory?
An individual point particle in the standard model is described in string theory as a mode of vibration of a string. If for some reason the mode of vibration of the string changed, the particle would change to a different one.

How do you change the frequency of strings?
Frequency(f)1 of vibration(or waves ) produced on the string is directly proportional to square root of tension in the string, inversely proportional to square root of linear mass density of string, inversely proportional to length of string. Changing any of one or more of these will change the frequency. A sonometer will serve as a good experimenting device. The various parameters can be changed and change in frequency can be observed. 1. Frequency here refers to natural frequency, for forced vibrations the frequency will be same as the frequency of force that produces the vibration.
How is the higher note produced on a single string of a stringed instrument?

Higher pitches can also be played by lightly touching a string at its exact midpoint while plucking it, which suppress is fundamental pitch will allowing its harmonic to sound. This would produce a sound one octave higher.
What is a fundamental mode of vibration?
The fundamental frequency is the lowest mode of vibration of a system. If you think of a taut string, the lowest mode with which it can vibrate is the one where the centre of the string travels the maximum distance up and down so the string forms a single arc. It is also possible for it to vibrate so that two arcs (one up and one down) fit into the string, and there are many more possibilities with higher frequencies. On a stringed instrument you can hear the fundamental frequency as the normal note which the string plays, and the others as overtones. Other systems exhibit the same phenomenon.
How do vibration in a tin-can telephone pass from one can to another?
By making the string tighten for the particles to go through
What do you do when you pinch the guitar string?
If you pinch or "pluck" the guitar string then let it go (based on how far away you let it go from the fretboard), you will get a "slap" effect. This is where the string "slaps" against the fretboard to give it a sharp twang before resuming a vibration. This is a classic effect often used on bass guitars, though there are different methods of doing this. One of which is to sharply knock the string into the fretboard and very quickly pulling away with the side of the thumb so that the string can still make a decent vibration.
How can you change the pitch produced by a vibrating string?
To raise the pitch (frequency), put more tension on one end of the string. To lower the pitch, put less tension on one end of the string. For instance, on a guitar, tighten the string for a higher pitch. Loosen the string for a lower pitch. Additionally, if you have a guitar string already mounted and tensioned. You may place your finger in the middle of the string, and the pitch will go up one octave. Each time you halve a tensioned string, it produces a pitch one octave higher.
When do you use intonation?
In guitar playing, intonation is the exact amount of tones that each string will raise by as you move your finger up the fretboard (along the string). So basically each fret should be one tone above the one below, but if its 1.1 tones then by the time you get up to the 10th fret you will be 11 tones above the open string when you should only be 10. That said i remember the whole 'tone, tone, semitone, tone' thing so I'm not sure if a fret is 1 tone or a 1 semitone but you get the idea right? Basically if you're intonation 'is out' it means that one or more of your strings doesn't provide the right note when played higher up the guitar.
