I don't know how high you want to go but B5 is within 3 Hz of 990 and E6 is within 2 Hz of 1320. In both cases the 2-3 Hz is probably within the error of the reference.
At higher tones even 5 Hz (C6 = 1046.5, D6 = 1174.7) is probably acceptable to all but the most highly trained ear since the error is < .5%. I know that being able to use 520 Hz (C5=523.3 Hz) is far more natural than either 500 or 550 Hz. 73, ... Joe, W4TV > -----Original Message----- > From: O.
