Virtual Reverie Harp
This is Version 1.
I have tested this version on desktop browsers. It works in Chrome, Firefox, and Edge. I don't know how well it works on mobile platforms.
I welcome feedback and suggestions. Just click the "Questions - Feedback" box in the lower right.
This Reverie Harp is coded so that the mouse works kind of like a pick. As you move your mouse cursor over the string, it will sound that string. You don't need to click the string, just move your mouse over the string.
