Question about breathy, windy shinobue tone

Q & A: Why is my shinobue tone so windy and not clean?
​

Answer: A common mistake I see among beginners is the tendency to blow too hard into the shinobue. This can produce a windy sound. It's important to learn how to use your core muscles to propel the air rather than relying on your mouth. This begins with diaphragmatic breathing. Focus on making your breath slow but heavy rather than slow and light. Many people refer to this type of breath as "warm breath," in contrast to "cold breath." I will be releasing a video about this, so stay tuned!
