The internet has a question for the PF members who are also musicians. Is quantum physics easier than playing this guitar piece?

The double lead guitar technique was invented by George Harrison on Your Bird Can Sing but the style didn't catch on. Jimmy Page put it on the map in Ramble On, then the Allman Brothers made it their signature. I like double lead guitar because that unique soaring sound is something no other...

How can I find the sustaining time of an electric guitar? The influence of other components besides the strings can be neglected. I need it for my term paper.

Does anyone else experience this? I've played the guitar for a few years. A somewhat annoying thing is that to me, open G strings always sounds like they are somewhat out of tune. Fortunately, fretted notes sound OK, I only have this problem with the open string. Please note that this is not a...

Hi, my name's Cass. I finished my bachelors in physics last year. Kind've floating around I guess. I write code, play guitar, make art, and study Japanese. I hope to spend some time away from school and get my priorities straight then maybe go back to gradschool eventually. Nice to meet you!

You already know about Crossroads and Red House, so skip those. Etsushi Ogawa [ 小川悦司 ] I like the way this builds so gradually. You also get to see Senri Kawaguchi wearing a Peter Pan collar. John McLaughlin -- Tokyo City Girl I dunno that anyone else will like this but it's my fave...

This isn't a question about torsion pendulums because it goes well beyond linear physics. The question is roughly, how many times can you rotate the end of a steel string, with the other end fixed, before it breaks? Also, how does the torsion distribute along the string? I tried to answer both...

I am a high school student and recently I have been working on a project about how temperature affects the frequency of a string emits. I have read blogs like https://www.physicsforums.com/threads/tension-and-frequency-with-change-in-temperature.833185/ and completed the part of thermal...

Hello - thank you for reading this, and thank you in advance to anyone who replies and clarifies the mystery of "ground." I have finally gained a full understanding of how a full-wave rectifier, two-power tube electric guitar amplifier works in a push-pull manner, but one thing remains after I...

(a) When a taut string is plucked with a finger then it starts vibrating with a transverse wave pattern in the string, which causes the air particles in the immediate vicinity of the vibrating string to oscillate. These oscillating air particles will result in a sound wave traveling in 3...

This wiki page offers an incomplete equation for calculating tension over a length of string. Can you please help complete the equation? https://en.wikipedia.org/wiki/String_bending It is referenced here in this thread post #23...

I've trying to explain this to myself but I know I'm missing something. I tuned the low E string to B. The frequency of that note is about 62 Hz. When I play that note under the led lights in my backyard I can see the string oscillate back and forth. After doing some reading, the LED light...

Hey! I'm and undergrad in the third year of my applied physics program. I'm taking a course in Special Relativity, and due to Corona the exam has been replaced by a pretty free project where we delve deeply into a topic related to the course. I'm interested in music, so my professor suggested I...

Sorry if this is the wrong place for this question. I am a musician and recording engineer trying to learn about why my bass guitar recordings sometime appear with the waveform going up first (positive polarity) and other times going down first (negative polarity) in my DAW (digital audio...

We’re tuning a guitar using harmonics, and we produce, on our properly tuned E-string, a frequency of 329.6 Hz when we pluck the first harmonic. The second harmonic, on the A-string, is noticeably higher, producing a beat frequency of 1.5 Hz. What is the frequency produced by the harmonic on the...

I built a guitar (fuzz) effect, and analysed the sine wave from a tone generator through an oscilloscope. Wondering what the wave means and how it got to be the way it is. I will attach a picture of the oscilloscope screen + the circuit I used for the Fuzz effect. My question is what the cause...

I have built several guitar amps, but the last one I built burned out a capacitor, can anyone think of a reson for this? it was an eloctolytic, all is working fine now I replaced it.

I tried using the general EMF equation but don't know how to apply it with the equation from the problem

Hello, I have a guitar amplifier I'd like to convert into a bluetooth device. Using it's current power supply and allow it to receive a bluetooth input. I have a bluetooth speaker that I took the electrics from. The bluetooth speaker is digital, but when it outputs to the speaker it's an...

Im interested in using ultrasound to intrfere with sound that comes out of guitar amplifier or sending ultrasound together with normal guitar signal in amp. My questions are : Is it possible? What will it do? Is there anything like it that i can look into? Thank you very much

I am working on synthesis modelling of guitars, and I have managed to capture most elements of the guitar well so far. Something I am struggling to understand is why a guitar string has a natural "beating" sound to it, meaning it sounds as if it is ebbing and flowing slowly as it vibrates. To...

Homework Statement When unfingered, a string on a guitar vibrates at 627 Hz. What frequency will the string produce when fingered one third of the way from the end, that is only two thirds of the string can vibrate? Homework EquationsThe Attempt at a Solution I am not too sure what equations...

I want to build a bass guitar stand for my guitar using wood, I'm modelling it after the image shown. The alterations I'm making are to increase the height of the legs , to place an attachable weight below the stand . This will allow the stand to have a lower center of mass and will greatly...

Homework Statement When a guitar string is stretched to have a tension T, it produces a frequency f. You change the tension by a very small amount ∆T . Show that the new frequency of the guitar string is fnew = f ( 1 + (delta T)/2T) For example, a guitar string has tension T = 10N and...

Hello, The guitar is a stringed instrument with six strings of equal length but different linear mass density. Fretting is about shortening the length of a string which causes the fundamental mode and higher modes to have higher resonant frequencies. When a guitar string is plucked (by hand...

Homework Statement The electric guitar radiates very little sound directly, but instead relies upon pick-ups (transducers) placed beneath the strings. Establish, showing clearly how you reach your answer, which harmonics of the open string you are likely to observe if the pick-ups are placed...

Hi guys, I would be grateful if you could help me out with this problem, I've worked though it myself, but my answer to part c is very large, which is making me doubt my answer, and in turn making me doubt my answer to part b Homework Statement The midpoint of a guitar string executes s.h.m...

My question is simply 'are all notes produced in a guitar produced by first harmonics?', but I will clarify what made me ask this question. Now, if you have a wave driver you can make several harmonics in a string by increasing the frequency of the machine. In a guitar string, however, it does...

Homework Statement A guitar string with 0.60 m and 0.012 of mass vibrates with frequencies that are multiples of 109 Hz. Approaching to the string a tuning fork of 440 Hz we verify beats between the sound signals of the string and the tuning fork. Calculate the time interval between consecutive...

I play the guitar since my sixteen. Back then a classical guitar was all I could afford. I went to a musical school for about two and a half years but that was not the thing I wanted to do. I was baffled by musical staff and classical pieces on guitar that were really great but not what I wanted...

Hello, I am currently taking the IB program and have decided to write my EE (extended essay [4,000 words]) in physics. I am going to investigate electric guitar pickups and I need help adding more 'depth' to the essay. Currently, I plan to create my own model pickup by winding a coil of enamel...

Hi, I wanted to ask if there would be a problem or two if I placed my pc on top of the head of the marshall half stack amp, the harddrive is about 65ish cm away from the center of the speaker (4x12inch speakers) and the power supply of the pc is about 50ish cm away from the center of the...

Homework Statement You have a ukulele and you change the strings tension so that it becomes tighter. First the frequency was 431 Hz and after we tightened the string the frequency. how much bigger does the force have t be to get that frequency? Homework Equations PA*V^2 = F (P = density, A =...

My question is fairly simple, but I'm having a hard time finding the answer. A guitar body dampens the vibration of a guitar string to some degree by contorting slightly as the string oscillates, and then producing sound waves and heat in turn. My question is; is it the mass the of the...

Hi all, I've been reading up on the physics of waves in order to better understand what goes on with sound. I'm having difficulties understanding how harmonics are produced in guitar strings. It's probably not as complex as I'm making it in my head, and it's really starting to frustrate me...

C=130Hz G=196Hz D=293Hz A=440 Hz The distance from the nut to the bridge is 58cm, the amplitude of the string vibration is 2.2mm Part A: What is the period (T) of the G string? Part B: What is the side to side velocity of the g string? (Think simple harmonic motion) Part C: The diameter of the...

Several of my students have pointed me to this video: http://bit.ly/1N1IGR8 Apparently the guy put his cell phone inside his guitar and took a video. My initial reaction was that it looked fake, because the time scale of the movement of his thumb seemed mismatched to the time scale of the motion...

It's a very simple question but still, When two identical guitars are played day two persons to give notes of the same pitch, will they differ in quality? Please specify with reason. Thanks for the replies.

I have put together an equation whose purpose is: With a desired 'magnitude of static friction' ( μ_s ), 'fundamental frequency' ( f ), and 'tension' ( T ), initial conditions such as 'string breakover angle' ( Θ_0 ), 'nut-tuner distance' ( L_{h,0} ), and 'string diameter' ( d ), and...

At one point I had been trying to construct an equation which would calculate the tension on a tuned string with a change in temperature (and therefore the fundamental frequency), but found my calculations were wrong. By extension, the purpose of the project was to be able to calculate what...

I am a computer programmer, mostly in Windows, but a little bit into open source, Linux and Java. I work a lot in javascript and SQL of one kind or another, both of which are utilized somehow via all common platforms. I am also interested in music, physics, and chemistry. I play piano and...

This is not a homework question per se, but rather something I have come across during a homework project. Using Audacity, I recorded a few different instruments playing the same notes (investigating timbre). I noticed that (using a steel string acoustic guitar) the first harmonic at 131 Hz...

So I have a program that works for a guitar, and sinewave and a saw tooth wave . so If a have person sing a note, it should work for that right ? I am not talking about sing a whole song but just a note. so like when people sing the scales: do ra me fa so la ti do is should would for that right...

I suspect my question will be somewhat unique, please forgive me if it's entirely out of place. (Please also forgive my ignorance when it shows, my knowledge of physics is extremely limited.) You might wonder why I'm asking it here, rather than on a guitar forum. Let me simply say that the...

Why is it that my FFT does not work when I play a note on a guitar ? I even tried audacity and it did not work . Is there some thing else beside a fft That I can use that can work for a guitar ? So if I play a C I and the program to get me the right frequency that is being played . My fft and...

I do have a question on a project that I am doing now (for my personal enjoyment) I bought an nice handmade classical guitar that was dropped on the tail-block and cracking it and putting two nice crack from the end of the guitar to the sound hole. Since I only invested $100 I decided to use as...
