Musical Slide Rule for Creating Scales in All Keys

Kids play with the slide rule like a toy and have fun playing piano scales!

Even if they're loaded with sharps and flats!

Here's how:

The top train has animals sitting on different cars. The child simply slides the top so that the engine is over the first note of the scale. Then he plays the piano key which is under each animal car. That's all there is to it! He can play every major scale.

The Major Scales Slide Rule has been tested in actual teaching sessions. It works. The keys on the slide rule are the same size as piano keys so that the entire ruler can be placed behind the keyboard. (See below)
