I'm looking for information about a particular style of notation for representing the chord progression in a song. I've heard musicians just call it a "chord chart". But when I search, "chord chart" seems to mean a chart of finger positions.
It's kind of a like a lead sheet or fake book, or even closer to slash notation, but with the staves and other unnecessary things removed to make it more compact. I've seen Nashville notation written this way, but this isn't that since it's using lettered chord names.
What is this chart called? And if possible, what software and file formats are used to generate a chart like this?
