|Multitouch Whiteboard app|
But what I was really hoping to find was an app that would allow me to draw on top of an image that I created and saved on my iPad. For example, if I created a grand staff students would be able to draw clefs and notes using the whiteboard. Found it!
For $1.99 I would recommend the Multitouch Whiteboard, which you can find in the app store. You can choose different colors and customize your marker width. Two people can draw at the same time. I especially liked that erasing and clearing did not alter my background image.
I made this image of the staff and keyboard in Photoshop and saved it in my iPad's iPhotos. When you open the whiteboard app you will find the option to select a photo for your background. Voila, a fun and handy teaching aid.
