The Chop Notation Glossary is the central part of a larger work known as The Chop Notation Project. The Chop Notation Project is a written work (free PDF download) which creates and establishes a standardized music notation to read and write percussive the bowed string technique known as chopping, bringing it up to speed with the current playing practice. Created by Casey Driessen in partnership with Spanish violinist Oriol Saña, and through consultation with other recognized “choppers,” the hope is that a system such as this will enable composers and players to share and communicate their musical ideas more easily across the globe. This video focuses on detailing and demonstrating the Chop Notation Glossary portion of the project which includes all symbols needed to read/write the technique. It is meant to be used in conjunction with additional explanations and tips found in The Chop Notation Project paper. If you'd like to download a copy of the paper, please visit
