I would need a list of translations for the technical parts and mechanics of the piano from German/Italian or English/Italian. Does one exist? I need it to explain things to my Italian clients and also to understand everything written on this forum.
In my opinion, you won't find the model with parts in both languages, but looking at the Italian model you will certainly find your way because the various parts are all represented with the references:
Certainly, there is a book published by VERLAG DAS MUSIKINTRUMENT - FRANKFURT AM MAIN. Authors: Nikolaus Schimmel and H.K. Herzog. Title PIANO NOMENCLATUR. All parts and terms concerning the piano in the following languages: German- English- French- Italian- Norwegian- Spanish. It can be purchased from piano suppliers that sell specialized books on the piano.
