You can create new chord diagram shapes by editing an existing one; for example, if you want an alternative voicing for a chord or to show a barré. Your changes to existing chord diagram shapes are saved as a new shape, they do not overwrite the existing one.
Tip
If you want to define multiple new chord shapes at once or start a new shape from scratch, you can do so in the Edit Chord Diagrams dialog.
Procedure
Result
The new shape is saved and is used for the selected chord diagram. The new shape also becomes available for any other chord for which it is valid.
