What Chord

By Mark Carlotto

Open iTunes to buy and download apps.


What Chord is a chord detection app that automatically detects musical chords in live music. Model-based algorithms match harmonic intervals to major, minor, diminished, augmented, dominant 7th, minor 7th, major 7th, sustained 4th, diminished 7th, minor 7th with flat 5th, and minor with #7th, picking the chord with the best match.
