Piano Cords

Posted on February 19, 2014 in News

When we spoke to sharpen a piano, we talked about the action to realise a series of adjustments of minims measured on the tension that own the cords of the instrument in order to indeed align the intervals of their tones for a correct interpretation of notes. Firstly for a good refining it is had to have present that all the pianos do not require of the same refining and measured equivalents, is had to evaluate the interaction between notes of each, since they are different in each instrument, and later to fit the heights according to corresponds. Generally the instruments like the piano, are sharpened to a modified version of the system, which is called equal temperament. In order to be able to correctly realise the refining of the piano at issue, a series is due to have present advice who are very recommendable as much actually with the instrument, refining and maintenance. As it is it its location, we must consider that if it is a tail piano, is advisable that this one is placed in center of the room and if outside vertical, next to a wall, but always avoiding that communicates with a kitchen or laundry, since the humidity causes damage in the components of the piano and directly affects the sound.

The piano at least requires of a refining and completion of 2 times per year, arriving to be even 5 times following the situation in which is the machinery. The approximated tension with tense which a cord of the piano goes up to around the 90 kilograms and if we avoided this detail and we did not tighten correctly, the cords of the piano will be yielding on their own tension and the pegbox maintains that them, entailing to a loss of frequency and more than probable breakage, increasing of this form the cost of the repair. A regulation will be due to also realise and fits of all the mechanical elements of the machinery that supports to the piano, observing flaws and differences in the escapes, hammers, extinguishers and also will be necessary to pay great attention in the existence of differences of weight between the keyboard of the instrument, to be able to correct them. The heat is a great one enemy of the pianos and directly affects the tensions that exert the cords to each other, is vitally important that we try to protect it of those factors. At the time of carrying out all these tasks of refining, they are due to realise by an expert person in pianos, since this one is the one that by means of its means and knowledge advanced on the subject at issue, will be able to determine which will be the suitable tension and as the parameters recommended on the basis of our profile, the machinery of the piano and the frequency with which we are going to use the instrument. It is necessary to especially emphasize that in cord adjustments, we will have to stay to the margin and to call to the specialist, since we could favor with our inexpert manipulation a joint breakage of cords and unsquare the pegbox, which would entail to a total unlevelling of all the cords.
