Remember: A Miyazawa is a lifetime instrument. By decoding its serial number, you unlock its history—the year it was forged in Nagano, the era of its mechanism, and the value it holds today. Keep that number safe; it is the single most important piece of data for your insurance, your repair log, and your legacy as a flutist.
The serial number is often repeated at the base of the post near the low-C key. Miyazawa Serial Numbers

The recurrence ( a_n = a_n-1 + a_n-3 ) yields: [ 1, 2, 3, 4, 6, 9, 13, 19, 28, 41, 60, 88, 129, 189, 277, 406, 595, 872, \dots ] This sequence grows with ratio tending to the real root of ( x^3 = x^2 + 1 ), approximately ( \psi \approx 1.465571 ). We denote this the Miyazawa coefficient . The serial number is often repeated at the
