Casey Henry teaches an arrangement of "Ashokan Farewell" in the key of D. This is largely based on Tom Adams's arrangement that appeared in Banjo Newsletter.
The lesson is taught entirely by ear--no tab. You can find many more lessons--all taught by ear!--on her website, as well as on the Murphy Method website.
