I’ve dabbled with tablature and chord software on and off for many years, and I’ve been consistently struck by an unfortunate fact: There is no public source for programmatic chord data.
So I started building one.
The following JSON file should meet almost every need for standard guitar tuning (EADGBE) and ukulele tuning (GCEA). But I want it to include other instruments like Mandolin and other tunings like DADGAD.
It should, with very little tweaking, be compatible with the chord.js chord chard rendering library (making my own tidier version of this library is also on my agenda).
hopefully there can eventually be a canonical source for chord data online.
