Chord Transition Insights

Select two chords on the left panel (e.g. C Major as Chord A, and C Minor as Chord B) and click 'Load Comparison' to populate the piano roll. You will hear the bright third (E) drop down to the melancholic minor third (Eb) in real time at 60 BPM, creating a classic emotional harmonic shift.

Lush Pads: These synthesizer tones are designed with a slow attack (150ms) and long release decay (400ms) to emulate a warm synthesizer keyboard pad. Perfect for studying harmonic transitions!
