Therese is playing a reproduction of the 17th C. “Boston Harp”, currently in the collection of the Boston Museum of Fine Arts. The replica was built by Catherine Campbell, Port Townsend, Washington.
This arrangement of the popular Torche Branle by Praetorius can be found in Therese’s book “The Royale Harpist”. You can watch more of Therese’s performances (of both early and Celtic music) here.
