This is a javascript database of string instruments chords. Open, free to use, easily improved with more chords.Contributions are welcomed, still a lot of chords (and instruments) missing.Use the pull request feature of Github to add your desired chords if you want to contribute.
Take a look at the chords database of an instrument to understand the schema used to register new chords.For example, let's take a look at theDsus2 chords of guitar. We can see this information in theD/sus2.js file:
export default { key: 'D', suffix: 'sus2', positions: [{ frets: '0320xx', fingers: '031000' }, { frets: '55775x', fingers: '114310', barres: 5, capo: true }]}
Eachposition define a new chord variation of theDsus2 chord.We must define thefrets needed to obtain the chord in the respective strings.We can define too thefingers information for easy reading of the chord.If the chord need to barre some string, we will define if in thebarre field. Ifyou want the barre be represented with capo, you can define the "capo" property too.
This project is usingyarn as package manager, so all the basic command related tothe project lifecycle are bound to it. Three basic commands
Generates a new version of the library when new chords are added.
Make some testing of the new added chords. Very useful to detect basic mistakes.
All this information is packed in a JSON library, that you can use to render visuallywith a utility able to parse this information.
You can take a look of the current state of the database with this SVG rendering tool:
