Even if you know how to play the piano wonderfully, there could be lots of information you do not really know about it. Do you know what happened to it since its invention up to the present? Do you know how it produces its tunes? In this article we will be happy to deepen and enrich your knowledge about this wonderful instrument.
The invention of the piano
In Florence, Italy, lived a man named Bartholomew Cristofori. At Late 17th century and early 18th century, this person, who was curator of musical instruments and therefore had a great knowledge of the music world, Bartholomew invented the piano based on another instrument called a harpsichord. The difference between the instruments is that piano is also percussion.
Since then, many modifications happened. The hammers were wrapped with leather in the past, which was later replaced with felt. The mechanism also has undergone many changes in order to allow the hammers return to place faster so that the same key can be stroked rapidly several times to make the same sound .
Moreover, during the early 19th century piano manufacturers began to produce the frame to which the strings are connected from cast iron, instead of wood. That gives the option to stretch the strings more and without risking breaking the frame. Stretching the strings bring the result of beautiful, clearer and deeper sound. At the same time, the strings were also replaced with steel strings. The combination of the two allows producing a continuous, deeper and crisper tone. Since the 19th century until today, pianos continue to be built in the same way, which means that the same sounds that were once heard are still heard today.
The structure of the piano
External examination of this instrument reveals 88 black and white keys, and so it can be concluded that this is a keyboard instrument. But the internal part of the piano, the sound box, contains stretched strings attached to a wooden frame. It is indeed both a string and a keyboard instrument.
The keys wrap small hammers, which are attached to the strings. Clicking on one of the keys causes the hammer to pluck the string, the string vibrate and produce the sound.
The instrument with the highest range of sounds, except the harp, is the piano that can reach more than 7 octaves!
The piano mechanism has additional elements :
Dampers - stopping the string from vibrating as soon as the key is released.
Two pedals. The right pedal – its role is to cancel the dampers and sustain the note.
The left pedal – its role is to decrease the volume of the sound.
