The tones produced when pressing a key on a telephone are standardized as per the table below---two tones are played, one high-frequency tone and one low-frequency tone. The low-frequency component is determined by the key's row on the telephone, and the high-frequency component by the key's column, as shown. None of these are pure, consonant intervals, which is why the key tones seem like "random beeps" when pressed in succession. But looking at the frequency ratios for each key, which has the largest pitch interval? Which has the smallest interval? What musical intervals are each of them closest to? The key has the largest pitch interval, which is an octave.
