Introducing Chordious, an app to create your own custom chord diagrams

by Jon

Chordious IconToday I announce the first release of my latest software project: Chordious, an open-source chord diagram generator for stringed instruments like the ukulele or guitar.

It’s the secret sauce behind the two sets of ukulele chord charts I’ve released in the past month, for both standard and slack-key tunings. At the moment, Chordious is a small command-line app that takes a config file of desired chord diagrams and generates them in clean, beautiful SVG graphics. Whether you want to make some chord charts of your own, or just spice up your song sheets, Chordious is the app for you.

Chordious isn’t just for ukulele, you can create diagrams for any stringed instrument. By default it produces very nice uke chord charts, but you can tweak and adjust the output to make the chords you want. Here are just some of the features:

  • Outputs to clean, scalable SVG images
  • Configurable styling, including:
    • Diagram height and width
    • Font size and family
    • Number of frets and strings
    • Specify top fret and barres
  • Bulk creating from the command line with Chordious.CLI.exe

For download links, check out my Chordious page, or the Chordious project page at Launchpad. You’ll find links for both the binaries and the source. Note that you’ll need at least .NET 4.0 or the latest version of Mono installed to run Chordious.

Happy chording!


P.S. As of right now the app works, as evidenced by the chord diagrams I’ve already made, but it’s by no means complete. For example I left room in the design for barre chord arcs, but since I didn’t need them personally, they currently don’t do anything. The next big thing I plan to tackle is to a graphical chord designer, to make designing the chords faster and easier. Stay tuned!
