If you are talking about conventional western music and equal temperament, an octave has a frequency ratio of 2:1 and is divided in to 12 parts (semitones). Find E and F next to each other on the piano keyboard. Hi, I was curious as to how adding/subtracting a fraction of a semitone affects the key in terms of transposition. IIRC, a semitone up from a certain frequency is (frequency)x2 1/12, so I assume a cent up from it is (frequency)x2 1/1200. I've done a calculator and incorporated the calculation of Camelot Easymix key codes, where 1 semitone equates to 7 steps round the easy mix wheel. For a transpoition intervals are the appropriate measure, so one would simply call it a sixth, because 500 cent would imply a precision, which is not intended. Frequency [in hertz] is a linear measurement system, tones/semitones/cents are a non-linear measurement system.) Still have questions? Cents work well for fractions of a semitone - it's easier to say 30 percent of a semitone rather than 0.3 semitones, and both are easier to understand at a glance ratios such as 40/39 etc. adding decibel values and converting between frequency ratio and cents/semitones) The website can also be reached via www.focalpress.com Professor David M Howard lectures on music technology at the University of York's Electronics Department. δοτζο.
