Guitarist Steve Baughman teaches his fingerstyle arrangement of a Celtic harp tune with an unwieldy title—Turlough O'Carolan's "Squire Wood's Lament on the Refusal on His Halfpence." The piece is in open G tuning, with a low C. Full lesson online at https://acousticguitar.com/tips-on-arranging-celtic-harp-songs-for-fingerstyle-guitar/
You can find Baughman's lesson, which includes the notation for his beautiful arrangement, in the March/April 2022 issue of AG (https://bit.ly/3nLgCNU).
