Abstract
Si tratta di un pianoforte a corde perfezionato con sistema di corde in sospensione, poste in trazione, fissate alle estremità con punte d'aggancio e tensori o caviglie, dove, da metà tastiera verso le frequenze acute, ogni nota (o coro) è formata da quattro corde poste in vibrazione dalla percussione di un martello (di legno ricoperto con feltro) azionato da un meccanismo di leve (meccanica-tastiera) messo a sua volta in movimento dalla pressione esercitata con le dita sul tasto corrispondente.La pressione esercitata dalle corde tese, agisce su dei risonatori d'attacco singoli e mobili su di un piano inclinato direttamente fuso nel telaio in ghisa, su dei risonatori della scala duplex singoli e mobili, su un ponticello, sul capotasto.It is a stringed piano perfected with a system of suspension strings, placed in traction, fixed at the ends with coupling points and tensors or ankles, where, from the middle of the keyboard towards the high frequencies, each note (or chorus) is formed by four strings vibrated by the percussion of a hammer (of wood covered with felt) operated by a lever mechanism (mechanical-keyboard) in turn set in motion by the pressure exerted with the fingers on the corresponding key. The pressure exerted by the strings taut, it acts on single and mobile attack resonators on an inclined plane directly cast in the cast iron frame, on single and mobile duplex scale resonators, on a bridge, on the nut.
