Hello, I've been hard at work on a project that I would like to share with you. It's called YouTab and its what I believe is a great way to sync lyrics and chords with music. The smart guys I work with use a nifty algorithm to "listen" to the music and in a lot of cases it does a really good job in getting the chords. But since technology has its limits there's an editor application that lets you fix what is wrong. I…

Certainly love the concept! And the UI flow and automatic lyrics-to-chords feature appears to have worked on my song just great. But... it doesn't seem to play, which is kind of a bummer.. Maybe the server is being swamped? https://www.youtab.me/music/XnWT_wslaBc/lindsey-simon/its-a-...

Plays fine for me but the start of the verses are completely out of synch lyrics->music. By the end of the verse it's fall in to synch however, then in the next verse it falls out' again - appears to have problems handling the long gaps with no lyrics.

You should send an email to the guys at http://chordify.net/ . One of the people involved in that project has a PHD in computer science with focus on analysing music with code. They'd be great people to team up with for you.

Chordify works pretty well. One criticism: it doesn't handle meter or speed modulations mid-song very well.

Why does it think this video https://www.youtube.com/watch?v=fTNzykQba3s has anything to do with Glenn Gould? https://www.youtab.me/music/loK8Eby47RZ/glenn-gould/goldberg...

It tries to figure out the artist by itself and as with all automatic things like this it missed sometimes.

You have an editor to fix the chords. Is there a way to fix the metadata?

Can it understand the difference between a composer and a performer?

I tried it with a song that is very familiar to me, "Antonio's Song" by Michael Franks, using the top hit in Videos for this Google search. It is in 4/4 time and the beat doesn't vary at all. It has five different actual chords: Am7, A7, Bm7b5, Dm7 and E7, and the pattern of chord changes is quite conventional in a verse-chorus structure. The algorithm did a so-so job of determining the chords. It rarely noticed that they were seventh chords, instead identifying them as Amin, Bdim, Dmin and E. It appears to rely strongly on the bass part. In one case there was a C# passing tone in the bass between an A7 and a Dm7 chord that was identified as a C#aug chord. I didn't try the editor. I guess this would make it easier than entering all the chords from scratch, but it struck me that there was still a lot of manual work to make it accurate and usable.

Both this and Chordify are really awesome endeavors! However, I find them both to be erratic in accuracy to the same degree. Many times, a major in a simple I-IV-V pattern will turn into a minor, or vice versa, or a simple major will excitedly be read as a major 7th. It must be a huge pain in the ass trying to pluck out these harmonics and to accommodate for all sorts of wacky instruments, so I'll let it slide! Both services are tremendous if only for getting the initial framework for a song and figuring out some of the incorrect chords yourself.

Does YouTab have a "confidence" rating for each chord? I don't know if it'd be the best UX to include that number for each chord (and maybe even alternate chord suggestions), but there are times when I'm simply playing along with the song incorrectly and it takes me a couple amateur minutes to correct the one chord that Chordify got wrong.

Great stuff, anyway!

One idea for a feature: you might want to include the ability to move the chords up or down a few half-tones. Some folks will use various tricks to move their instrument up or down a few notches in order to make the chords easier to play. The tool needs to be able to adjust for that.

I agree that the site is DMCA compliant, you've covered that. lyrics added by the users for tracks that musixmatch hasn't got the rights to will probably still be a problem. the chords are, I guess, no problem, as you can't copyright a chord progression. the big problem however is the embedding of material from soundcloud and youtube. while strictly speaking it might be legal, the total experience of your site is sev…

Thanks for the insight. I agree that a 3rd party media provider such as YouTube & SoundCloud has it potential for problems. It's not a perfect solution I agree. I have been toying with re-attaching tabs to different audio sources when a video dies for example. I'm not entirely happy with current results. It should be automatic, which I have a pretty good idea on how to do, but haven't gotten around to implementing ye…

I just checked the competition, they still suffer the same problems you're facing : most videos simply won't load, a lot because they can only be viewed on youtube, some are blocked (for me at least), some are gone.

I guess society isn't ready yet.

Worked great on the first song I tried. Thereafter it crashed my browser several times (FF 31). Would be awesome if you could mix in/out with the actual song a MIDI track of the chords themselves, just to verify that they are correct.

Very nice. You know one feature I would love to see are strumming patterns. It's nice to see the chords but it's tough for an amateur to identify the strumming patterns.

I have been thinking a lot on how to implement this feature. Showing it easy enough, but creating strumming patterns is a bit of a challenge... This is my favorite feature though.

Maybe an algorithm that could identify for ex first played note - meaning bass or first string and continue the same with other chords. After that you know where to start. Also there are only few strumming patterns and if you know the measure it should be easier. Just an idea.
