piano ALIGNMENT & STRINGING

Tuning up:

in order to experience real pleasure in playing the instrument, it is necessary to have it well tuned up. Pleasant sound of all tunes is the criterion for correct tuning. For a well-tuned instrument, all sounds must equally harmonious and leave an equivalent impression at every octave and every tonality.
Three categories of tuning up exist: daily, preventive and concert. Private clients hire a tuner, when somebody of the family plays a piano. Still, even if an instrument is not used, it is necessary to tune it on a regular basis.

Intonation:

it is necessary to fine-tune mechanical parts and to attune unisons clearly before to undertake intonation.
A master of pianos can change the hardness of hammer heads at the point they hit strings. We call it intonation of a piano. The intonation is regulated by loosening felt on a hammer by needles or by hardening it by binding liquids. When intonation needles are inserted into felt of a hammer, we make it softer. So, the contact area of a hammer on a string increases, as well as the time the hammer touches it. As a consequence, high tunes are softened. If felt will be loosened too much, the hammer will become too soft, and the tune will be stressed too much.

Regulation and repairs of mechanical parts:

The mechanisms of pianos and grand pianos help to turn the movements of a piano-player’s fingers into sounds. The main parts are: a mechanism, a keyboard, hammers and dampers. They are made of high quality wood, various metals, broadcloth, felt and leather.
