The ChordPro for WordPress plugin (ChordPress) reads and processes ChordPro formatted text, including several content and formatting directives, and renders it for WordPress sites.
What is ChordPro?
The ChordPro site introduces this text format as follows:
In 1992 Martin Leclerc and Mario Dorion developed a simple text file format to write lead sheets, songs with lyrics and chords, and a tool to create neatly printed lead sheets out of these text files. The tool was calledchord, and the text files were calledchordfiles. It soon became a popular way to write lead sheets and many users and tools adopted this format for similar purposes. For still unknown reasons people started calling the fileschordprofiles.
