Everybody can learn relative pitch. You may think you have a wooden ear, but you can learn relative pitch with practice. This is a tool to help learn pitch relative to a key. It plays the note of the key, then another note relative to the key. As you get better you can increase the number possible notes it can pick. Start on the easiest setting, and move slider to more difficult settings when you master the current level. You can also click on the notes in the grid to customize the repetoire.
And if explanation doesn't make sense, don't worry - this page isn't useful to you, go back to reading about the robots. On the other hand if intervals are too easy, then try the chord training exercises page.
