Hello

Keyboard instruments such as pianos have black keys in groups of two and three.

Among the white keys, the left side of the two black keys is do

Then to the right is re/mi/fa/sol/la/si...

To the left is si/la/sol/fa/mi/re /do. . . . . .

In addition, I suggest you learn it

It is better to treat it as a toy than to learn it in a down-to-earth manner

I hope you will adopt it
