Great for those with basic skills. – Music Tool LE Review

If you have gone through basic music theory, or at least know which notes are which in each cleft, and have heard the word key signatures, then this app will save your life if you are learning the piano. Although the keys are a little junky, the fact that it has the circle of fifths built right in, and shows you have to play major and minor keys in different key signatures, makes it a great app for an even greater price.
