Tips for a better result
- 01Find the original key first.
Use "Find the key and BPM of a song" to know where you are starting from.

Up to 3 semitones, most songs keep a natural sound.

Use "Remove the vocals from a song" and change the key of the instrumental.

MP3 is smaller; WAV keeps everything for another program.
Common questions
Does the speed change?
No. Only the key changes; the song keeps the same tempo and length.
How many semitones should I move?
Each semitone is half a tone. To go from C to D, use +2. For a voice, moving 1 to 3 semitones usually sounds the most natural.
Will it sound robotic?
Small changes sound natural. The further you move, the more the voices change color, especially beyond 5 semitones.
