Everybody can learn to recognise chord progressions. You may think you have a wooden ear, but you can learn with practice. This is a tool to help learn and recognise common (and then uncommon) chord progressions. It plays the base chord of a key, then some other chords relative to the key, and then the base chord again. As you get better you can increase the number possible chords it can pick.

By default it uses a major root chord, and chooses only one of the the major-4, major-5 and minor-6. I suggest: start with the major-4 and major-5, then progressively add add minor-6, minor-2, minor-3, major-1, 5-7th, 4-major-7th. If that last sentence meant nothing to you, don't worry - this page isn't useful to you, go back to reading about the robots, or start out with the interval training.
