What else can I help you with?
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.
Where the the nodes of the standing waves of a banjo in the string?
In a banjo, the nodes of standing waves on the strings occur at points where the string does not move, typically at the bridge and the nut. Between these points, there are also additional nodes along the length of the string, depending on the mode of vibration. The fundamental frequency has one node at each end and one antinode in the middle, while higher harmonics introduce more nodes and antinodes along the string.
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".
Tone produced by one vibration of a string?
The tone produced by one vibration of a string is called a fundamental frequency. This fundamental frequency is the lowest frequency at which the string will vibrate, and it determines the pitch of the note that is produced.
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 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.
Waves are produced through what?
Waves are produced through the vibration or oscillation of a medium, such as air for sound waves or water for ocean waves. This vibration creates a disturbance that propagates through the medium, carrying energy from one point to another.
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 you know that a resonance has occurred between the fork and the string?
If there is resonance, then making one vibrate will also make the other one vibrate in a noticeable way, since:* The vibrations are transmitted through the air, and * Any such small effect is reinforced, over time, due to resonance.
A fundamental tone has only one?
A fundamental tone has only one frequency. It is the lowest frequency produced by a vibrating object and is also known as the first harmonic.
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.
What is the frequency of a wave equivalent to a strings vibration?
i am assuming your talking about musical instrument strings?? well, each string vibrates at different rates. when tuning a guitar for example standard tune is at 440 hertz [or wave modulations] so although all the strings are different size thickness or gauge, we're able to "tune" the instrument by changing and adjusting each strings "frequency" hope this helps !!
