If you’d like to add “blackboard ABC” (or is it really “whiteboard ABC” these days?) to your ABC notation, this tool may help. You may have to hand tweak the output in some cases. See Reading ABC Notation in Irish Traditional Music for more information on this format.
Load an ABC file or paste your ABC below.
Check the output to make sure it’s OK and hand tweak the w: lines in the ABC if you need to.
Don’t forget to ‘Download ABC’ to save your work.
