The Scottish Lute vol. 2, The Highland King
Mel Bay Publications, USA, 2003
Tunes from the Wemyss, Rowallan, and Balcarres lute books, in tablature and also in staff notation. There are only a few tunes from the early Gaelic harp repertory but they are really important ones - two settings of Da Mihi Manum, and also Port Atholl and the Horsemans Port. These are early 17th century settings which may include elements of early clàrsach harmony, phrasing and idiom.
