At the Bibliothèque Nationale in Paris there exists a very unusual 17th c. music manuscript for solo viola da gamba (lyra viol), a tiny, leather-bound elongated book of 270 pages. Compiled by at least eight different individual hands, it is generally thought to originate from the Brandenburg region in northern Germany. Never published in a facsimile or modern edition, viola da gambist and Art d’Echo ensemble director Juliane Laake found a way to organize its great number of pieces into a coherent and presentable narrative. What you hear is a record of her exploration, sleuthing and discovery.
