An orchestra tunes to a frequency of 440, which sounds the A above middle C. Each octave higher doubles the frequency, and each of the 12 semitones in the octave increases the frequency in the same ratio.
a)What is the ratio? 880= 440 x b^12, b= 1.059
b)Find the frequency of middle C. I can't work this out. The answer is supposedly 262 but I can't get this.
c) Where on the scale is a note with a frequency of 600?
I cant get the answer to this either which the book says is "between D and D#".
Thanks for any help you can provide.
