NumberChords
The story behind the collection
-
About ten years ago, I started playing numberchords from the booklets by Johannes de Heer. Before long, I developed a desire to play a broader repertoire than just psalms and hymns. That's why I began transcribing sheet music into numberchords, which eventually resulted in hundreds of pages of handwritten music using this system.

During this process, several obstacles emerged: not all musical notations could be directly translated into the existing numberchord method. After years of experimenting and refining, an improved numberchord system was developed, offering greater possibilities.
