Brief Model Notes
The μ (pronounced “Mu” and sometimes rendered as “u”) was Yanagisawa’s attempt to move and resize toneholes to create a better sax. Whatever Yani learned from this project was rolled into the 901 and 991.
As far as I’ve been able to determine, the μ was only available in alto and tenor. If you have a different pitch and it has “901μ” or “990μ” stamped near the serial number, please drop me a line. I’d love to see pictures.
Serial Number Information
For the majority of horns, you’ll see a serial number starting with “00” that does not have an embedded date. Check out my thread on the Woodwind Forum for these serial numbers and some odd ones that I’ve found.
