The piano was invented in the 18th century, likely by Bartolomeo Cristofori. He named it the gravicembalo col piano e forte, meaning “harpsichord with soft and loud,” referring to the pianoforte player’s ability to vary the volume of the notes s/he is playing.
Playing the piano requires dexterity precision and I wonder, do pianists make fewer typos than non-musicians? Judging by my own typing errors, the answer is no—but then, I’m not exactly a virtuoso on either type of keyboard.
Pinao* is a high probability typo on the Ballard list, occurring 37 times in Ohiolink and over 400 in Worldcat. With the asterisk, this includes pinaos and pinaoforte.
