Theoretical fundamental piches of all eighty-eight notes. The box includes the twelve pitches of the temperament octave (in
red) .This table was computed with a calculator by multiplying each successive half step by 1.0594631 (the twelfth root of two). Although the above pitches are rounded off to three places, computations were carried out to six places (five places, from C6 up).
