This Scottish strathspey sounds great on the harp and is easily achievable for intermediate players.
The first verse features a simple accompaniment; choose to play only this version if you are a lower intermediate player. The second time through, I've added grace notes, rolled chords and some parallel passages, none of them too hard for solid intermediate players.
Intermediate level. In A Dorian (key of G). Two pages of music. No lever changes, brackets, or fingerings.
