By taking songs from YouTube, SoundCloud or files uploaded to the website, Chordify breaks down songs into their composite chords, transcribes them then displays them for the user to follow. More experienced musicians can choose to see chord labels at the point which they're supposed to be played and absolute beginners can opt to see the chords represented on a diagram of a guitar. Chordify therefore obviates the need to read music when learning chords.
Despite being operated by sophisticated technology - automatic chord transcription algorithms, to be precise - Chordify is surprisingly straightforward to use and is roughly 75-90% accurate. And right now it's free. It has the potential to generate an entirely new way of learning an instrument (albeit with limited scope) and re-engage people with non-digital ways of making music.
