Here’s an idea on making music more accessible and fun. I always enjoy someone that thinks out of the box.
I use the stairs leading up to my Studio to teach children about about steps and skips on the music staff. Each stair represents a half step on the keyboard. So the first stair is D, second stair, C#, next one D. I then do flash cards with letter names and the kids have to step up or down the stairs like a music staff saying the letter names of the flash cards out loud.
You can also use the stairs as half steps and tell children to go up a third, down a second and use the stairs for interval work. If you are a guitar teacher pretend that each stair is a fret on the guitar.
