My first flute was done and I began to learn more about how to play it. Tuning was the next challenge. I have a pretty good ear for music, though I am not a musician. Guitar yes, but flute no. I knew enough to know when the notes were off key. But how to tune a flute was going to take some time. This is where experience comes into play. I found out that the more flutes I made, with different characteristics; length, bore size, tune hole spacing, etc., the more I learned how to tune each flute. The sound produced by the NA Style Flute is both relazing, and mystifying.
