Tonfall generates random tasks at different difficulty levels. These range from simple settings with treble clefs and no general accidentals to complex settings with tenor and alto clefs, six general accidentals and several accidentals.
This enables targeted training in identifying triads and intervals. You can choose between fixed lessons and free training with predefined or self-configurable settings.
Visual feedback is presented after each task and lesson completed. Special achievements are rewarded with badges.
