Paula,
Thanks for your question. This one is tough and has required some research.
Perhaps the place to start is with Tabledit.com.
It’s a program that allows you to load sheet music PDF and convert to tabulature.
It would be possible to load the PDF sheet music enclosed at the bottom of each lesson and convert to tab.
Another option is to use a program called Songsterr. (Spelling is correct two Rs at the end). It is an AI based program that lets you drop in audio files and it produces tabulature.
I have some experience with Tabledit. It’s pretty handy. No experience with Songsterr.
I hope this helps.
George
