Chordify: Chord transcription for the masses

Chordify is a web-based music player that strives to help people play any song on a (harmony based) musical instrument. Our web-service automatically transcribes the chord labels from an arbitrary audio source, and presents the chords to the user in an intuitive manner. Next, the chords are used as an interface to the music: during playback, a cursor highlights the currently played chord, and users can select the chords in the sequence to play or loop any fragment of the audio source.
