>... on my machine they are all flat by 3-4 cps. >12 cents off is perfect? But I wonder if someone with >really perfect pitch would recognize this?... ---ric Wondering won't do it, Richard. I have no doubt that some with absolute/perfect pitch would easily know the cents discrepancy you mention exists, while there would be some who would not, yet still would be able to identitify the correct note/tone. My position is that 12 cents off A440 doesn't negate the note/tone from being in the domain of A440. However, 51 cents + or - does. It is measurable, much in a fashion as a property line. Decide for yourself by taking into account the following reference sources: ---- Absolute Pitch 2. Music. The ability to identify or sing any tone heard. In this sense, also called perfect pitch. (American Heritage Dictionary, Electronic Edition) ---- Perfect pitch, the sense of pitch that enables a person to identify a tone heard and name it as a note on a musical scale; absolute pitch. (Dictionary, World Book Encyclopedia) ---- "Absolute, or perfect, pitch is the ability to identify by ear any note at some standard pitch or to sing a specified note, say G, at will. Fully developed absolute pitch is rare. It appears early in childhood and is apparently an acute form of memory of sounds of a particular instrument, such as the home piano. Some musicians slowly acquire a degree of absolute pitch, if only for the familiar a' =440." http://www.britannica.com/bcom/eb/article/4/0,5716,61724+1,00.html ---- "Absolute Pitch."
