Assuming C4 = 261.63Hz and Just temperament: 15/8 = ratio of major 7th to fundamental 4/3 = ratio of perfect 4th to fundamental 2/1 = ratio of ocatave to fundamental
B3 = (261.63 x 15/8 / 2) = 245.28
To get to Cb, we need to traverse the circle of fourths: C -> F -> Bb -> Eb -> Ab -> Db -> Gb -> Cb
F4 = (261.63 x 4/3) = 348.84 Bb3 = (348.84 x 4/3 / 2) = 232.56 Eb4 = (232.56 x 4/3) = 310.08 Ab3 = (310.08 x 4/3 / 2) = 206.72 Db4 = (206.72 x 4/3) = 275.63 Gb3 = (275.63 x 4/3 / 2) = 183.75 Cb4 = (183.75 x 4/3) = 245.00
