Great tool.
Very useful. For those complaining about this app not having guitar tabs.....learn how to read music. Tabs have made guitar players dumber.
No tab
This app is great if you can read music but if you're like me (and a lot of other folks) and rely on tab, don't waste your money. I'm guessing the rest of the apps by these guys are the same. No tab!
Wonderful
My director Edward Freytag recommended this app because the creator is a former student of his. Man, this cat made a great resource. Even if you aren't a jazz musician or an someone trying to improv, this is an all around amazing tool to access music theory. Thanks for this man!

Really immense.
Fantastic
I play both trumpet and piano, and this app really helps to not only learn the structure of nearly every chord out there, but it's also just a fantastic way to aurally "fish" for chords, searching for the kind of flavor I need when doing improv. Good stuff!
