I was excited to try this app. FIrst, no instructions or guided walk thru. So you have to figure it out yourself - which was frustrating, the visual layout is amateurish. I sooo wanted this to be better. If you are looking for an app that will show you a 2 thru 5 note chord and then let you play it, so you get the kinisthetic connection of repetition while at the piano, then I'm sorry to tell you that this isn't it either. TO the Author: I hate to slam your hard work, - please Make this better and I'll pay 10 or 20 times the asking price and will happily update this review. You are 80% there, there is no reason you can't clean up the interface, provide instructions, and even add Midi support - make it so folks can play what they read and progress in difficulty, with repetition of chords they are weaker on.
