Is that really done? Gosh, I hope not. I always notice shift in some unisons after the whole thing is finally tuned. Final unison check before presenting an invoice is a must, IMO. > The best test of a unison I've found after you get done messing with it is > to play the octave to a previously tuned unison.

It's not something I always do, but it works well. Did this earlier this afternoon at a concert tuning. With four octaves, going up and down chromatically. Really shows up even small errors. Have you also noticed that 3rds make pretty good unison checks? Minor 3rds in the tenor/midrange, and major 3rds in other places. -- JF -------------- next part -------------- An HTML attachment was scrubbed...
