A little information about myself: I have been playing violin since I was 5. Why do I mention this you may ask? Well you see the tone and sound that violin make connected to physics. (wow our world is surrounded by physics) For those who don’t know a violin has four strings and infinite about of sounds it can create. The sound I made when the strings vibrate. This vibration is created by either plucking the strings or by the action of the bow on the string causes the string to undergo a so-called slip-stick motion. These vibrations can be altered by the use of vibrato or the speed or pressure placed on the bow or by changing the tension in the strings. As the bow is pulled across the strings the force on the bridge increases in the direction the direction the bow moves but the string moves in the opposite direction of the bows motion. The vibrations that are created are transmitted through the bridge into the body of the violin which then bounce off the wall of the violin creating observable sound. This sound that the violin produces to the ear is a fundamental pure tone aka a harmonic aka notes with frequencies that are integer multiples of the fundamental.
