Why I created this?

First of all, thanks to Keith Horwood for the code to generate the notes and the keyboard!

I have taken singing lessons, and have been given patterns to practice with.

Although I know some music theory, and could learn to transpose the patterns, I'd rather focus on my singing practice.

I was able to take the five common patterns and code the original work of Keith to play these patterns and increase the notes played using the right arrow key.

Next improvement would be to get the left arrow key working to decrease the pattern notes!
