THE PIANO-FORTE -- Here you will find a collection of articles discussing different factors influencing the social and musical role as well as the materials and shape of the piano during the middle 1800s. Important accounts in patents and endorsements of different manufacturers' contributions help tracing the paths followed creating todays designs, but developments also can be traced according to the varying degrees of success of authors copying each other - due to their understanding of the instrument or language - and sometimes provide useful impressions of their own day's instruments as finished products.
