Does anyone here play piano? I recently learned Fur Elise but the more I play it the more my pinky muscle gets sore and usually I just have to quit in the middle of the song from these weird pinky muscle spasms. Does anyone know how I can make my pinky muscle stronger? Will it eventually be...

Hello everyone, I am new here and so I apologize in advance for the many forum faux pas I am likely to commit. I am not particularly well educated in the field of physics, but I am a piano tuner by trade, and we work with issues every day that are basically problems of physics and engineering...

Ok this problem seems blatantly easy but for some reason I just cannot find the equation. Homework Statement The middle C string of a piano is supposed to vibrate at 261.6 Hz when excited in its fundamental mode. A piano tuner finds that in a piano that has a tension of 900N on this...

A 500kg piano is being lowered into position by a crane while two people steady it with ropes pulling to the sides. Bob's rope pulls to the left, 15 degrees below the horizontal, with 500 Newtons of tension. Ellen's rope pulls toward the right, 25 degrees below the horizontal. (a) What...

Identify the forces acting on the object of interest. From the list below, select the forces that act on the piano. 1. acceleration of the piano 2. gravitational force acting on the piano (piano's weight) 3. speed of the piano 4. gravitational force acting on Chadwick...

My recall of the formulae is as rusty as the piano strings I am experimenting with. I want to replace the strings in an old grand piano. I have miced the measurements of the old strings. There are only six changes in diameter of the trebled strings. I would like to recalculate and try for a...

I've always wanted to learn, since as far back as I can remember. I've always been envious of kids my age who already touted their fluency with the piano and being so young, but I figured I was not ready to devote myself to learning. It didn't help that my family was not musically involved. I...

Homework Statement Question: Standing Waves: A steel wire in a piano has a length of 0.7000m and a mass of 4.300 x 10^-3 kg. To what tension must this wire be stretched in order that the fundamental vibration correspond to middle C (fc=261.6 Hz on the chromatic musical scale)...

I am not sure where this is exactly suppose to go but I need some help with the mathematics behind musical theory. I searched the forums and didnt really find a related topic. The instraments I play are guitar and piano. I recently started the piano though and it made me question many things...

A student on a piano stool rotates freely with an angular speed of 3.33 rev/s. The student holds a 1.44 kg mass in each outstretched arm, 0.759 m from the axis of rotation. The combined moment of inertia of the student and the stool, ignoring the two masses, is 4.34 kgm2, a value that remains...

A piano whose mass is 132 kg is being lifted at a steady speed from ground level straight up to an apartment 7.3m above the ground. The crane that is doing the lifting produces a steady power of 470W. How much time does it take to lift the piano? Sorry for so many topics, I do appreciate the...

A 500 kg piano is being lowered into position by a crane while two people steady it with ropes pulling to the sides. Bob's rope pulls to the left, 15 degrees below horizontal, with 500 N of tension. Ellen's rope pulls toward the right, 25 degrees below horizontal. What is the tension in the...

A piano wire (Y=2.0*10^10 N/m^2) has a radius of 0.80 mm and a length of 0.76 m. One end of the wire is wrapped around a tuning peg whose radius is 1.8 mm. The other end is fixed in place. Initially, there is no tension in the wire. Find the tension when the peg is turned through 2 revolutions.

Piano playlist I don't know what to put on it! I know I want these "I Allegro Maestoso" - Sonata No. 8 in A Minor K310 (Beethoven) "Appassionata" - Sonata No. 23 (Mozart) "Moonlight Sonata" - Sonata No. 14 in C sharp minor (Beethoven) The Minute Waltz (Chopin) Für Elise (Beethoven) And...

Hi, this my first time asking a question, so here it goes: A 255 kg piano slides 4.6 m down a 30° incline and is kept from accelerating by a man who is pushing back on it parallel to the incline (Fig. 6-35). The effective coefficient of kinetic friction is 0.40. (a) Calculate the force...

I have a 300 kg piano being lifted at a steady speed from the ground to a hieght of 10 meters and the crane that is doing the lifting is providing 400 watts of power. How much time does it take to get the piano to the top. So far I have Power = work/Time so time is Work/ power , so, work is...

Hi, could someone please help me? Here is the problem: "A 265 kg piano slides 4.6 m down a 30° incline and is kept from accelerating by a man who is pushing back on it parallel to the incline (Fig. 6-36). The effective coefficient of kinetic friction is 0.40. (a) Calculate the force...

Anyone know any sites that I can learn to read piano notes and play it from scratch?

A 393 kg piano slides 3.7 m down a(n) 27° incline and is kept from accelerating by a man who is pushing back on it parallel to the incline. The effective coefficient of kinetic friction is 0.40. (a) Calculate the force exerted by the man. (b) Calculate the work done by the man on the piano...

Hi, this is my first post on here hope I can answer some in the future. I've finished everything except these two problems. I've got the answers except I can't figure out how to arrive at the conclusions. 1) A 4.2-kN piano is to be slid up a 3.5-m frictionless plank at a constant speed. The...

ok certain notes have 3 strings. the rightmost string of a note loops around a peg and becomes the leftmost string of the next higher note. so if you increase the tension on the first, you have to increase the tension on the adjacent. right? well i thought so too, yet I've had 2 piano...

im 17 and i have a keyboard at home i used to do keyboards in yr 6 in school and went on to do it in yr 7 but the teacher was crap and was taking a lot of money so i quit. but i really want to learn to play the piano. most of my friends play an instrument and they've been playing since they were...

Hello, I thought I knew how to solve for this problem but alas I was wrong. I'm hoping someone will be able to point me in the right direction. Here's the problem: A 1.40x10^2 kg piano is being lifted at a steady speed from ground level straight up to an apartment 18.0m above the ground...

A 2.80*10^2 kg piano is being lifted at a steady speed from ground level straight up to an apartment 12.0 m above the ground. The crane that is doing the lifting produces a steady power of 4.00*10^2 W. How much time does it take to lift the piano? i know that i have to use the equation Time=...

What are some impressive compositions to play on a piano? I'm trying to master Für Elise by Beethoven and am having a lot of fun doing so :biggrin:

Anyone here knows how I can make my piano sound recorded in a mp3 file play faster, or slower etc using computer programming? I am not talking about using WinMedia and changing some of its options, but...uhmm..Yes, I think it is the same way as to how such options I believe are to be created...
