Downloads

If you don't want to deal with compiling or managing the Go source, you can download a binary built for your OS from the releases page.

Example

chorduroy -f X554X5 -o Am6.png

Usage

  -f string
    	Fingering (from highest) (default "X554X5")
  -o string
    	Path at which to save diagram (default "diagram.png")
  -s float
    	Number of frets to include (default 6)

chorduroy guesses the number of strings on your instrument based upon the fingering you provide. For example, if there are four characters in your fingering, the output will have four strings:

chorduroy -f 232X -o ukeG.png

chorduroy will also intelligently guess when a diagram can be "offset" to show chord patterns higher on the fretboard:

chorduroy -f 787X -o fretOffset.png

Roadmap

• Modifiable image size with commandline flags
• Custom colors and toggleable alpha/transparency
• SVG / PDF export
• ASCII output
• Web service to use online

Probably not planning on:

• Barre notation. This is intended to indicate position, not tell you how to play.
• Fingering suggestions. See above.
• Instrument-specific notation
