The main model chosen by NEUPERT for the creation of this instrument was a fortepiano by Johann Jakob Könnicke (1756-1811), Vienna 1796.

However NEUPERT did not restrict itself to copying an instrument slavishly. Individual elements from fortepianos by Anton Walter and Johann Andreas Stein were added to the instrument's construction as well as the workshop's own ideas. The result is a fortepiano distinguished by the light touch and the delicate, bright sound of authentic instruments from the classical and pre-classical period.

The five octave compass of this keyboard was never exceeded by Wolfgang Amadeus Mozart and by Ludwig van Beethoven not earlier than in the "Waldstein Sonata" (op. 53 from 1804).

For decades, during which the instrument was continually improved, NEUPERT 's MOZART fortepiano has successfully passed the demanding test of numerous concert halls, opera houses and conservatories. At the same time it has proved to be the ideal instrument for amateurs, playing the music of Mozart and his contemporaries at home.
