<HTML><HEAD><TITLE>Re: Octave Tuning</TITLE></HEAD> <BODY> <BLOCKQUOTE> <BLOCKQUOTE> <BLOCKQUOTE> <BLOCKQUOTE> This item keeps coming up once or twice a= year.  I have to say that I have never tuned a unison that= I thought was too clean.  I've always thought that a unison= that was too clean was like a girl that is too pretty, or a food= that is too good.  I've also never heard anyone else's unison that I= thought was too clean.  I know there are those who disagree and that's= fine.  I have just never done it myself. dave __________________________________________ David M.

Another way= that concert-level tuners get “all there is” out of a piano when= tuning---and a big part of the psychoacoustic illusion that is= created by a good tuning (i.e., “you voiced it!” or “the action= feels so much better” when all you’ve done is tune.)
