Hi Pete, thanks for the query. You can edit or add to tunes in the TTA by clicking on the "Edit" function in the top right bar of the Lonesome Fiddle Blues page. That will open up the page for modifications. I assume you use abc's, which you will need to add music. Once you've completed the abc entry in the "Edit" mode, simply click the "Save Page" button on the bottom left, and the page will reconvert to regular with you score. Or...you can always email me with the abc changes and I'll be glad to enter them. Regards, Andy Kuntz aikuntz57@gmail.com
