In which continent was the piano and guitar created?

The guitar's roots go way back to 15th-century Malaga in Spain. Its engineering was pioneered by a Spanish black man, who gave just four strings or ''courses'' to his guitar. Thereafter, the instrument went through the Baroque and Classical periods before evolving into the six-stringed, modern-day guitar.

The invention of the piano is credited to Bartolomeo Cristofori (1655–1731) of Padua, Italy, who was employed by Ferdinando de' Medici, Grand Prince of Tuscany, as the Keeper of the Instruments.
