Video Description:
Why does a piano have black and white keys instead of one simple row of identical keys? The answer goes back centuries, long before the modern piano was invented.
In this video, we explore how early keyboard instruments shaped the familiar keyboard layout, why black keys appear in groups of two and three, and why some notes have no black key between them.
