“While it’s true that in some schools a student formally graduates from one belt level to the next, in the Zen Guitar Dojo there is no such graduation. Students here receive one belt and one belt only: the white belt. Those who put in the time, training, and effort will find their belt getting so soiled that eventually it turns black of its own accord. Only then will they have achieved black-belt status.”
