Race to build a musical scale!
Find the notes in three types of musical scales on a keyboard by learning the rules for forming a musical scale. These types of scales are featured:
* Major
* Natural Minor
* Harmonic Minor
Scales are shown, sounded and can be built in seven chromatic pitches in this "free" version.
When you’re ready, you can have this game challenge you to form a scale of a particular kind. You can brag of your speed on Facebook. The app automatically adjusts difficulty level up and down depending on how you are doing.
