Excellent!
I am an experienced musician of almost 40 years. I also have seen (and presently own) some of the best music reference apps on the market. In the first release of this app, it is already one of the very best. It easily replaces three of the best piano reference apps I own. A terrific and well-thought-out resource. My only problem: theres little room for improvement. In a word, excellent.
Still trying to grasp all the information contained in this app. If youre serious about music, theres a lot of necessary info here.
