Tuning your guitar to DADF#AD or " Open D " tuning compliments Celtic guitar music perfectly. It is easy to create drones and overlap notes that sound reminiscent of a harp or bagpipe. The 30+ tunes represent a good selection of well known Celtic session tunes and songs. There are jigs, reels, songs, hornpipes, waltzes plus instructions on how to read tablature and note rhythms. There are also some DADF#AD chords, Celtic strumming patterns, major and minor scales, and a full DADF#AD fingerboard chart. I hope you enjoy this collection!
