There are dozens of piano apps out there that tell us they are “the easiest way to learn piano”. Of course, that’s pretty stupid. No iPad app is going to replace a piano teacher any time soon. However, there’s one new piano app that made a nice step in the Mus-Ed direction, and let’s you play dozens of songs using your own piano or keyboard (or on-screen touch piano). it’s called Piano Dust Buster and it’s even free.
