Chosen by BestEducationalApps as one of the Top 5 Music Theory Apps for iPad - "For music teachers wondering how to get their students to practice chord progressions and new theory topics at home, Music Tool could be the solution. This app is a simple dashboard of notes and chords that make those elements sound out when you tap them. For example, you can tap the C on the keyboard or in the list of notes, and hear the C. You can also tap the C sus4 chord and hear that chord. In addition to the Major scales dashboard, there is a list of modes that allows you to change the dashboard into a list of notes and chords used in the different modes."

Use of space

I'm reviewing this from an iPad perspective. It is still really helpful to figure out chords and seeing how they are implemented on the piano. Don't get me wrong, no other free app on the ipad is that good, yet.

The only thing I'm bothered by, is that the space on the iPad isn't fully utilized. I could easily see a lot more scales and the information could be better organized. Also, I might as well have found an app on the iPhone catalogue, as this app looks like it was scaled up... Poorly.

I'm glad it was a free download though.

I like the idea, but there are a couple of issues. Of the selections for key changes, two don't work. You can't access D, and G. I also can't access the 'Circle of Fifths'. The only other issue; there is no way to contact the developers from within the app. Why would I spend $4 for the full app when there are such essential parts of the LE version that don't work, and there are no way to address the issues? If they fix those issues, I will adjust my rating accordingly, and purchase the full version.

Update: I found out how to contact the Developer, and he was Great!!! He got back to me immediately, and suggested a couple of possible remedies. I will definitely purchase the full version.

Good stuff, but....

I'm excited about this app, but a couple of things I've noticed are a bit weird, and should be fixed if there's ever an update.
Instead of having the upper or lowercase of the Roman Numeral correspond to the type of chord (uppercase for Major, lowercase for minor) this app has the roman numeral corresponding to the numbered half steps within the scale. I don't know if this is different in different countries, but in America that is incorrect.
Which is confusing, to say the least. The only other problem I see is the absence of a relative minor option. The only thing it shows is a parallel minor. But that's not really a problem, it's just not handy.

But really, great app. Just don't trust the Roman Numerals. :)
