The construction of a piano emerges basically first on the drawing table in the form of various drawings: in piano making one speaks of a MODEL.
In constructing a piano, the interaction of various materials (metal, different woods, felts, leather, etc.) need to be taken into account, as well as the high tension of up to 20 tons that is built up, which makes the construction so complex that even today, the construction of a piano defies the most complicated of calculations.
The making of an extraordinarily good piano construction is therefore extremely difficult and requires years of experience and many practical trials, and can be performed by only a handful of the great masters among piano makers.
The ongoing production encompasses three piano models of different constructions. All models were constructed by the company founder in the ´20s and ´30s of the previous century, and were produced in larger quantities in the Viennese factory. Even today, many of these instruments are still serving their owners to full satisfaction, proving without doubt their superior quality and longevity.
