One of the BEST Music Education Apps!! Fun, too!!!!!

First of all, I am a seasoned music educator, but i feel that my piano skills are somewhat lacking. I understand the concept of inversions on other instruments (for example, on guitar). This app has helped me apply my knowledge to the keyboard!! I played through the first 5 levels of inversion invasion and I am HOOKED! Try it for yourself, a must-have app for anyone looking for a good time!!! Well designed game!!! 5 out of 5 stars!

Being forced to sit through the title screen, then being forced to sit through the lame dialog of the space man.... Makes this lame and unplayable. Just make it simple. Don't try and make inversions an adventure roll playing space game. Users of something like this really don't need the whole 'preparing to engage...' type dialog. It makes what is a good idea turn into something annoying. I'll be deleting it for these reasons alone. Try making it playable. We're interested in music theory, not space games.

Great fun!

I love this, although playing the chords without using my thumb is a bit awkward. Tap the text-box if you don't want/need the instructions or back-story...but I think that's part of the fun!
One wish...as a piano teacher, I would love for this to support multiple users...
