About
Polychrome Computer helps you compose music by analyzing your sung or hummed melodies. It identifies the key of your melody and presents the eight chords of that key, labelled by scale degree. You can then use these chord buttons to develop your progression. The tool offers various chord voicings, including sevenths, sus2, sus4, add9, and inversions. It runs offline after installation to your home screen. Audio input is analyzed in memory and discarded without being recorded.
