Thank you very much for viewing. I am a gagaku (Japanese court music) hichiriki (double-reed wind instrument) player with 50 years of experience, and I craft over 1,000 high-quality reeds annually. These reeds are made from high-quality reeds from Udono, with an outer diameter of 11.5-12mm. They are carefully selected, dried in the shade for about a year and a half, and then smoked over a irori (sunken hearth) for over 10 years, resulting in reeds that are both durable and possess excellent sound quality. Please refer to past reviews of my reeds to understand their quality. They are finished with great care, allowing for comfortable playing. They are finished so that even beginners and women can easily produce a sound. However, please be aware that they have a strong resilience and firmness, so they will not sound with a light breath. To produce a good sound, you must breathe into them with force. The price is a bit high, but I am confident that you will be satisfied with these reeds, so please try them. If you are not satisfied, I will handle returns and exchanges. If you have any questions or concerns about gagaku or the hichiriki, I would be happy to help. Thank you for reading this long message. I hope you will consider these reeds.
