Choral Lab brings the art of four-part Bach chorale writing to your iPhone. Whether you're a composer, music student, or theory enthusiast, explore one of the most refined harmonic styles in Western music. Harmonize your melodies. Draw a soprano line on the interactive piano roll and watch Choral Lab instantly generate alto, tenor, and bass voices following authentic Bach voice-leading rules — avoiding parallel fifths and octaves, resolving leading tones, and building natural cadences.
