Based on the Alain Benbassat method of ear training, this game trains your ear by playing some chords in a key (specifically, I, IV, V, I) to give you context, then playing the quiz note. You have to guess the quiz note by saying its solfege name (do, re, mi, ...). After revealing if your guess was right or wrong, a resolution is played to help reinforce the note in relation to the key's root.
