Georg Friedrich Handel's Water Music (Full Score). The publication of the new Urtext edition of Water Music makes the work available in a revised edition reflecting the latest research findings. In October 2004, the editor Terence Best found the oldest surviving manuscript score in the archives of the Royal Society of Musicians in London-primary source A, which can be dated to 1718. This discovery demands a drsmatic reappraisal of what is probably Handel's most famous work.
