Example 18.4 tells you that the adjacent notes E, F, and Fsharp can be assigned frequencies of 330 Hz, 350 Hz, and 370 Hz. You might not guess how the pattern continues.
The next notes, G, G-sharp, and A, have frequencies of 392 Hz, 416 Hz, and 440 Hz, on the equally tempered or chromatic scale used in Western music, the frequency of each higher note is obtained by multiplying the previous frequency by 12√2. A standard guitar has strings 64.0 cm long and nineteen frets. In Example 18.4, we found the spacings of the first two frets. Calculate the distance between the last two frets
