While Paul's harmonic advice is sound, you can accomplish the experiment
you're interested in doing with sound stretch, I think:

http://sky.prohosting.com/oparviai/soundtouch/soundstretch.html
"The sound Pitch (key) adjustable in range -60 .. +60 semitones (+- 5 octaves)."

A third would be 3 or 4 semitones, a fourth is 5 semitones and a 5th is
7 semitones.
