This reed is based on original diagrams and measurements from the 17th century. They are made using an internal scrape, taking the majority of the cane away from the inside of the reed. This results in a lighter, buzzier, more flexible reed with greater dynamic and colour range than what is known as a 'modern' scrape, which is done by removing the majority of the cane surface from the outer waxy bark, and leaving a thicker centre or 'heart' to the reed. The original reeds are without this strong central support, but instead gain their strength from what is left on the outer bark. The modern style reeds tend to give a more round, dark tone quality, which is infinitely easier to control, but gives perhaps less 'variety' of articulation and tone quality.
