This application will test your ability to recognize intervals and chords by ear. In both sections you will be given either a chord or an interval and you will be asked to identify them by name. After you answer each question you will be told if your answer was correct and be given a score for how well you've done on the test over all. Both sections will give you little options to make the test a little easier.
If you are new to ear training the interval section is where you would want to start (hint: learn to sing the major scale). The chord section is a little harder but can still be fun. This little app is like having a partner to test your ear, and that can really help. My ear has gotten a little better just from making and testing this thing. Good Luck.
