I know my mentor talked about M3rds as a unison check for the temperament region when I was learning to tune aurally (back in 2000). But I've "noticed" it again, especially when tuning the bass. On most pianos, I'll tune all the plain wire strings first, then tune the bass to them (all open strings). Unison problems are pretty evident in the m3-M6 test. That's where I got the idea for trying m3rds. With good unisons, the 3rds are clear, assuming no falseness, severe mismatching, or string leveling problems. I don't often use the 3rd to test unisons, 'cause it's kinda frustrating to hear tiny errors in unisons that might make it through the first check. Note: they are already good unisons ... the kind that no one would really question on the RPT exam. Ever picking nits, -- JF -------------- next part -------------- An HTML attachment was scrubbed...
