My data for the 1799 Meantone pic comes from the file supplied with TuneLab Pro, named "1799 Meantone.tem", which contains the following: A 0.00 A# 11.72 B -4.68 C 7.03 C# -9.37 D 2.34 D# 14.06 E -2.34 F 9.37 F# -7.03 G 4.68 G# 0.97 ----- Original Message ----- From: "Richard Moody" <remoody@midstatesd.net> To: "Pianotech" <pianotech@ptg.org> Sent: Sunday, February 17, 2002 8:19 PM Subject: Re: Pics Pythagorean, Meantone | You wrote....... | | "The 1799 Meantone ......" | | I would like to know the source of your 1799 Meantone.

The price for this is that the EB fifth is | 15 | | cents narrow (compared to the ET contraction of 2 cents). There are three | | varieties of thirds: four at +6.8 cents, four at +12.8 cents, and four | at | | +21.5 cents (ET uses 13.7 cents). | | | | The 1799 Meantone is clearly designed to have the fifths and thirds match | | each other. For the major triads on C, G, D, A, D#, A#, and F, the fifths | | are at -4.3 cents and the thirds are at +4.3 cents. (This is cents, not | beat | | rates, so I'm not sure if they beat the same ... more Excel work to | come...) | | The price for this is that three of the thirds are stretched to over 30 | | cents and must be unusable, and two of the fifths are actually *expanded* | to | | +8 cents and +11 cents respectively. | | | | || ||| || ||| || ||| || ||| || ||| || ||| || ||| || ||| | | jason kanter * piano tuning * piano teaching | | bellevue, wa * 425 562 4127 * cell 425 831 1561 | | orcas island * 360 376 2799 | | || ||| || ||| || ||| || ||| || ||| || ||| || ||| || ||| | | | | | | | |
