How do I change a song's key without changing its speed?
The short answer
Pitch & Speed changes pitch in semitones while allowing a separate speed setting. Keep speed at one times if you want the original tempo. Small shifts often preserve the character of a recording better than dramatic changes across a wide range.
Try this workflow
- Upload the song to Pitch & Speed.
- Set a small positive or negative semitone shift.
- Keep speed at 1x and compare the result before exporting.
What to check before you finish
Listen to voice texture, bass and cymbals as well as the new notes. Extreme shifts can introduce artifacts or make timbre unnatural. For a cover, choose a key that supports your range rather than one that only fits the first verse.
A practical example
For a singer who strains on the chorus, try moving the whole song down one semitone at the original speed. Sing both the lowest verse phrase and the highest chorus phrase over the result. The new key should fit the whole performance. If it improves one end but hurts the other, consider a different arrangement.
More questions
Does changing pitch correct individual wrong notes?
No. It transposes the recording as a whole; this tool does not provide note-by-note vocal pitch correction.
How many semitones are in an octave?
Twelve semitones make an octave in the equal-tempered system used by this pitch control. A small one- or two-semitone test is a useful starting point.
