Guitar Note Frequencies

April 22, 2010

I stumbled on a website with the guitar frequency notes and I decided it would be a good idea to post it for posterity… and just in case the site ever disappears or moves… It might be helpful as I try to figure out what adjustments to make to my equalization.

Tempered Scale

Over time, most of the musical world came to agree on a scale called the tempered scale, with the A note set at 440 Hz and all of the other notes tuned off of that. In the tempered scale, all of the notes are offset by the 12th root of 2 (roughly 1.0595) instead of the fractions we saw above. That is, if you take any note’s frequency and multiply it by 1.0595, you get the frequency for the next note. Here are three octaves of the tempered scale:
