The shakuhachi was traditionally used in Japanese temples to train the breath and the concentration. With this way of meditating, called “suizen”, concentrating on the breath produces sound. Hearing this sound gives peace to your heart.
Playing shakuhachi is my way to meditate, either with one tone or an entire piece. Meditating with the shakuhachi is different than practicing or performing. Just blowing a tone, without judgement, focusing on the breath, is quite a challenge for a musician!
