Notation on Harpejji:
Currently there is no way to accurately notate music for Harpejji, this has been a major issue within the Harpejji community. The lack of an agreed upon notation system greatly limits the communication of ideas and individual harpejji development. The best option currently avaialbe to share Harpejji musical ideas is a Tab service created by Mathieu something rather and shared on the Marcodi Harpejji website. This is limited because it’s not compatiable with regular written music. You also need an app to write.
I’ve created a system for notating harpejji music that uses standard musical notation.
