The combination tones between any two frequencies A and B are obtained by adding and subtracting the two frequencies: A + B gives the summation tone while A - B gives the difference tone. This principle can be extended to infinity if we consider second-order, third-order, (et cetera) combination tones.
For example, in the third measure of the last system the twenty-fourth partial of the loss, E, the [B.sub.5] (987.8 Hz) is also the first-order difference tone between the sixty-fourth and fortieth partials (64 - 40 = 24).
As indicated in the first measure of Example 10, the difference tone between the two generative pitches [C.sub.2] (65.41 Hz) and D[[flat].sub.2] (69.3 Hz) produces a rhythmic pulsation since 69.3 Hz - 65.41 Hz = 3,89 Hz.
This is mirrored in the way the voice often drops out, leaving the keyboard to contrast the levels of distortion depending on how muddy or consonant the chords are, and also lets us appreciate the low, gritty difference tones created between it and the voice.
lightbulb flashed, and she had the idea to reproduce the "difference tones" she had learned about from her accordion teacher--tones that result from the difference between two pitches--using the studio's oscillators.
