An easy-to-use musical ear trainer that uses a unique method to help you acquire perfect or absolute pitch. You learn a particular note by listening to a random sequence that includes the note. Whenever the note is played, your aural recognition is reinforced by visual stimuli that serve to connect the sound of the note with its name and position on the piano keyboard. When you are confident you know the note, you can take a test.

The registered version allows you to select any note in a four octave range, whereas the unregistered version only allows the selection of Middle C.
