Back in 2020, several people leading Irish tune classes and/or sessions contacted me asking if the online ABC transcriptions of the O'Neill's books (early 1900s) could be made useful to musicians using tablets or phones. If you're involved in such groups, feel free to send me your suggestions, too. Turning ABC into a useful tool for working musicians is something that's still "under development", as they say, and communication can help us implement and test ideas. The Internet isn't much like music books, and we have a long way to go to find the best ways to do things here. See also these explanations of this transcription project:
