For people who are not familiar, there are 12 steps in an octave. The frequency of the note doubles for each octave. Thus, each "step" increase the frequency of the note by 2^(1/12) times. So you have the frequencies of each semitone as roughly:
1.00
1.06
1.12
1.19
1.26
1.33
1.41
1.50
1.59
1.68
1.78
1.89
This is the reason why "Do/Mi/So" (1/1.26/1.5, ~4/5/6) or "Do/Fa/La" (1/1.33/1.68, ~3/4/5) sound good to the ear.
Incidentally, the way the piano is tuned is different from guitar, where piano tuning is more precise (closer to the 2^(1/12) steps), and guitar more close to the integer relations.
