I would like to see a more intermediary model, just for curiosity. Like the earliest kind of model that can be considered a grand piano. What is the minimun amount of inovation it require to be called a grand?
I think there really is no consistent definition of what distinguishes a fortepiano from a modern piano. The term 'fortepiano' is very broadly used just in the sense of 'vintage (grand) piano', as far as I know. A narrower definition would be everything that uses a wooden frame instead of a metal one; at least this is what I think of when I think of a fortepiano.
Personally, the distinguishing features that make a grand 'modern' in my book are: full cast-iron frame, choirs with at least 3 strings, felt rather than leather hammers, at least 7 octaves and a double-escapement action. If I am not mistaken, the development was largely finished at the end of the 19th century, however AFAIK many grands built between 1850 and 1900 were still missing one or more of those features, depending on the manufacturer.
For example, double-escapement and felt hammers were quite common from 1850 onwards, I think, but the full cast-iron frame construction was not. Many European grands of that time used composite metal frames, if I am not mistaken: stronger than the old wooden frames, but not as strong as a modern cast-iron frame. Because of this, those models probably had fewer and thinner strings and had a sound somewhere between a fortepiano and a modern grand.
So between 1850 and 1900 things are a bit muddled, and pianos from that time probably all are 'more or less' modern, depending on the make and model. Everything built 1900 or later could/should probably be considered 'modern', however.
PS: all this is talking about grand pianos. I have never really researched pianinos (uprights); they are younger than the grand (early 1800s?) and have probably undergone a similar/parallel development, but of course not identical.
