A very challenging tuning is EBEBEF# which has much in common with DADGAD. Both tunings have 3 strings tuned as the main root note of the tuning 2 strings being the 5th and one odd string out. In DADGAD the odd string out is the G which in the key of D is the 4th. In EBEBEF# the odd string is the F# which in the key of E is the 2nd. This tuning is essentially the same as CGCGCD capoed at the 4th fret.
