I think it takes 1200 Cents to raise a full semi-tone. Cents are the units of tuning accuracy. I read once that most human can not tell a difference of 5 cents. So if you want to raise a guitar string by a semi-tone and you only raise it 1195 cents in pitch then you most likely would not be able to tell the difference. It's like 4 quarts make a gallon, 3 feet make a yard, 100 pennies make a dollar and 1200 cents in pitch will raise a full semi-tone.

"Twelve-tone equal temperament divides the octave into 12 semitones of 100 cents each. Typically, cents are used to express small intervals, or to compare the sizes of comparable intervals in different tuning systems, and in fact the interval of one cent is too small to be heard between successive notes."

I checked it from Wiki. It says semi-tone is 100 cents.


Thanks.

Yes, a cent is 1/100 of a semitone, 1200 cents to an octave. - But I think that the term is only used for the equal temperament intonation that we commonly use in Western music.

Anyway, if the question was asked in case you're setting intonation, I try to get each string to...3 cents? You can go crazy getting spot on especially if you're using a little electronic tuner because the needle just wobbles all over the place. I'm not going to invest in a strobe tuner, but the 2 times I did- holy cow it was amazing how dead on my intonation was.

Or maybe the original question was more basic. A given note is a specific frequency and is measured in Hertz. If you double the frequency (Hertz), you have a one octave change. The low E string is 82.4 Hz. The E note at fret 2 of the D string is 164.8 Hz and the high E string is 329.6 Hz. It might seem simple to use Hz when talking about tuning, as in, the "tuning is off 10 Hz", but 10 Hz is a lot on the low E string, but not so much on the high E string. So, the term "cents" was created, that is actually a ratio of frequencies. There are sites you can find on the Internet that explain it clearly, but basically one cent is one "percent" error in the tuning, regardless of the frequency being tuned.
