Fret Frequencies on the Guitar

Published by Ruud Peter Boelens in

Create a function that takes a number of a guitar string and the number of the fret and returns the corresponding frequency of the note.

  • Check the Resources Tab, for the correct frequencies per string.
  • The formula to calculate the frequency is: String Frequency * 2^(fret/12).
  • Round the frequency to the nearest hundreth.
  • For this challenge, we use "Standard Tuning".

So, one fret = a semitone = a half step. From D to D♯ for instance.

Examples

fretFreq(5, 12) ➞ 220

fretFreq(4, 6) ➞ 207.65

fretFreq(2, 23) ➞ 932.32
