A piano for Mono Monday

The theme of 'an invention from any era of your choosing' left me drifting around the house (with Luca in tow), spoilt for choice...and therefore dithering.
Then my eye fell on the Yamaha keyboard we have downstairs, sitting in a small room lined with shelves of CDs (and Richard's extraordinary vinyl collection).
I was taught to play the piano as a child, but only in quite a stilted, hesitant way - much too reliant on reading notes rather than listening and learning.  Nor did I have the talent to overcome that approach.
So the real pleasure I associate with the piano comes from listening to others play, especially in jazz and latin traditions. Gonzalo Rubalcaba... Ruben Gonzalez... Abdullah Ibrahim... so many more. More recently I've been spending time at the keyboard with Luca, Frieda and Eben, hoping to give them a chance to explore the instrument, to develop both curiosity and confidence and perhaps to gain a desire for learning to play later on. Of the three, Luca is the one who shows the strongest response to music of any kind; it stills him, you can see ripples of interest and contentment move across his face as he listens.

Anyway: the piano - I discovered today - is considered to have been invented in Italy around 1700, by Bartolomeo Cristofori. Its ancestors include the dulcimer (which originated in the Middle East and spread to Europe in the 11th century) and the clavichord, which dates back to the 14th century.  There's some info here:
