HowDevices Work: Violin
Theway sound is produced by the violin is an interesting, but a simpletechnology. The device is a musical instrument that is most usedmusical instrument of the modern string family, with it being thehighest sound producing instrument of that group. But for over the500 years that violin has been around, the one question that manypeople ask is to understand how it violin works. I have not been ableto be in good position to understand how such a small instrument canbe able to produce a variety of tone and sounds with such power. Indiscussing violin, the paper will explore the principle behind itsworking and how it produces sound.
First,it is important to know that the source of sound produced by a violinhas all to do with the number of strings available and also its body,which resonate the sound being produced by the strings. The main ideahere is that when one plucks or hit a violin string then theviolinist has the ability to make it vibrate (Ficarra14).The aftermath vibration produced from the combination of the stringand the body has the consequence of making the air molecules aroundthe instrument to be excited and in the process ends up creating awave that we call it sound.
Itshould be understood that the strings themselves hardly make anynoise or sound in that case. This is so because they are thin innature and can be plucked easily without making much of anydisturbance (Ficarra19).Keep in mind that a sound wave comes into play by disturbance of theair. The violin bridge and body are the one tasked with theresponsibility of transmitting vibration into the air thus resultingin sound being produced.
Theviolin instrument is composed of a bridge that plays the criticalrole of connecting two structures inside the body of the violin thatis the sound post and the bass bar. The sound post is spread acrossthe instrument and has the responsibility of transmitting treblenotes being produced to the back plate of the violin (Hodson22).The bass post on the other hand, is tasked with the responsibility oftransmitting the bass notes being produced to the front plate of theviolin which has the ability of equally amplifying the lowerfrequencies when the instrument is being played.
Toproduce a meaningful sound note, the violinist is first required touse his/her off hand to try and restrict the length of the stringsthat are expected to vibrate, by plucking the strings at variousplaces, the violinists has the ability of adjusting the note beingproduced by a particularly string when playing the instrument (Saitiset al 84).The violinist then brings the bow across the string or stringsdepending with what he tries to achieve, as all this is happening theviolinist is altering the speed and force with the purpose ofadjusting the loudness and pitch of the end sound. From there, theway the body has been shaped and constructed officially takes over inamplifying the sound being produced shaping it for the targetedaudience.
Theviolin typically works with the plucking of the strings, when astring is plucked or bowed it has the effect of creating force inthe direction of the bow’s motion (Saitiset al 85.).While this is happening, as the bow continued plucking the strings,the aftermath force on the bridge increases in the direction of thebow as well. When the strings later on slips as a result of theviolinist pulling back the bow, the force that was initially creatednow reverses direction in an opposite direction to the bow’smotion.
