Piano tuning

The job of a piano tuner is to agree pianos and harpsichords, by regulating the tension of the strings and so the tones tunes harmonically. There are also other service work primarily with the customer and in the concert business and the optimization of intonation ( of sound ) by appropriate processing ( peeling, stinging, etc. ) of the Hammerfilze and the regulation of the piano action and the rise of new strings.

Training

The training as a piano builder in Germany lasts three and a half years. The job of a piano tuner in the EU is not always an apprenticeship, therefore not protected. But the learning of piano tuning is part of the training for piano and harpsichord maker. Previously, occasionally even today was and is learning the piano tuning a possible vocational training for blind people.

Technology

A piano tuner works with tuning fork or tuner, voice wedges made of rubber, felt or wood lederüberzogenem for damping mitklingender strings and a tuning hammer. It begins with the creation of the so-called temperature - octave, for example, the circle of fifths from concert pitch a1 from:

If you were here all octaves and fifths pure, therefore, vote beatless free, the last fifth would be much too tight. Because of this so-called Pythagorean comma is equally- tuned ( in the same floating temperature), that is, each fifth is a little too closely applied. After applying the temperature - octave you tune in octave up and down until all the tones of the instrument sound right, said to be mentioned that the outer octaves are usually " spread ", that is, one determines the upper tones higher, the lower deeper than they were mathematically (see extension).

Other methods to tune a piano, are also common. For example, you can create instead of the circle of fifths ( or fourths, fifths ) a Terzenzirkel (thirds and sixths ). Or do you tune a- a1 ( octave up), a- e1 ( fifth upwards ), a- d1 ( fourth up), e1 -h ( fourth down), h- f k1 ( fifth upwards ), fis1 - ck1 ( fourth down), cis1 - gk1 ( fifth upwards ), gk1 - dis1, dis1 -b, b- f1, f1 -c1, c1 - g1. Various control intervals for correct beat numbers are checked. In equally- scale atmosphere the beats of all intervals from bass to treble are equally fast.

One of the laity did not consider difficulty in piano tuning is the so-called "settling" of the tuning peg, the great sensitivity and appropriate exercise will require: If the correct position of the tuning peg is achieved by means of a precision rotary movement, the mood keeps better.
