The QB just makes it easier for two-dimensional (2-D) learners to learn music. I’ve been a musician my entire life (trombone/guitar). After hundreds of hours on the piano keyboard, I was unable to use it, even as a tool. I love the piano and especially the pipe organ. This dilemma, plus modern digital music advancement, led me to create the Quartal Board (QB).
All music creates geometric patterns on the QB. It has made learning keyboard music easier to learn for me-possibly for others with a 2-D learning preference. THAT IS A LOT OF PEOPLE.
