In fact, I don't think I've heard anybody break down how they do it. I then realized their method for doing it is quite useful and not often talked about. It's a little mind boggling when you first think of it, because having Cartman sing in harmony with a regular adult voice while changing up his semitones enough to actually achieve Cartmans voice would generally sound really off. So when you're hearing Cartman's voice, you're hearing it at around 4 or 5 semitones up from the original.īut wait, if he's pitching up 4 or 5 semitones, how are the voices on key with the songs that are being sung? Wouldn't he have to pitch up an entire octave to make it work? What if there are multiple children singing in that song? Each key you move up is also moving up a semitone and if you move up 12 semitones, you reach an octave. A cent is a small shift, and an octave is the same note but a higher or lower pitch.
When changing pitch, you deal with cents, semitones and octaves. In this video you'll see Trey Parker voicing Eric Cartman in his natural voice, and then again with the pitch up.
