Is it possible to play the generated chords as a melody by itself, without the original music over it? 2013/1/18 Alfredo Di Napoli

Congratulations! Keep up the good work, especially in using Haskell at a commercial level :)

Bye! Alfredo

That's awesome, works like a charm on the samples I've tried it on! Cheers to the Chordify team, I will use it and give any useful feedback if I have any.

Hi all,

I'd like to introduce Chordify http://chordify.net/ [1], an online music player that extracts chords from musical sources like Soundcloud, Youtube or your own files, and shows you which chord to play when. Here's an example song: http://chordify.net/chords/passenger-let-her-go-official-video-passengermusi...

The aim of Chordify is to make state-of-the-art music technology accessible to a broader audience. Behind the scenes, Chordify uses the HarmTrace Haskell package to compute chords from audio. I've been working on this project with a couple of colleagues for a while now, and recently we have made the website public, free to use for everyone.

We do not use Haskell for any of the frontend/user interface, but the backend is entirely written in Haskell (and it uses pretty advanced features, such as GADTs and type families [3]). We're particularly interested in user feedback at this stage, so if you're interested in music and could use an automatic chord transcription service, please try Chordify!

Cheers, Pedro

Hi all, Thanks for all the feedback and kind words. Yes, we're planning to have export to PDF/midi options soon. We have plenty of ideas, but limited time :-/ User feedback is collected (and voted for) on https://chordify.uservoice.com/ Thanks, Pedro On Fri, Jan 18, 2013 at 12:37 PM, Rustom Mody wrote:

Super work! I was meaning to ask something similar -- can we get out something of the music that chordify has reverse engineered -- maybe midi maybe musicxml?
