Changing a song's key for vocal practice with Yalaloop

Move the song to your key, then sing and play along.

Most songs I want to sing along with are recorded in a key that’s too high for my voice. “On My Mind” by Finn Forster is a good example: in the original key it sits too high for me to sing comfortably. I bought the song on iTunes, so it’s a regular audio file on my device that opens straight in Yalaloop. I pitch it down 3 semitones, and the whole song moves into my range — same tempo, same feel, just lower.

I use that pitched-down version in two ways: to sing along on its own, and to play the guitar part along with it while I sing.

Finding your key

Start from the original key and shift one semitone at a time while you sing the highest and lowest phrases of the song:

  1. Find the hardest phrase. Usually the top of the chorus. Loop it so it repeats while you try different keys.
  2. Shift down (or up) one semitone. Sing the phrase again. Keep going until the high notes feel easy, not just reachable.
  3. Check the low end. Play the verse at the new key and make sure the lowest notes don’t disappear. If they do, go back up a semitone.
  4. Leave it there. The setting is saved with the song, so next time it opens in your key.

Singing and playing along

When the recording is shifted, your guitar part shifts with it. Transpose the chords by the same number of semitones and play along — the recording, your voice, and your guitar are all in the same key. For guitar-specific practice, see Practising guitar with Yalaloop.

Common questions

How do I change a song's key for vocal practice?

Open the song in Yalaloop and move the pitch control up or down in semitones until the melody sits comfortably in your range. The tempo stays exactly the same. Go down a semitone at a time if the high notes strain, up if the low notes disappear. Often a shift of just a few semitones is enough.

Does the tempo change when I shift the pitch?

No. Pitch and speed are independent in Yalaloop. Shifting a song down 3 semitones keeps it at its original tempo, so you sing along with the song exactly as it was recorded, just lower.

How far can I shift the pitch?

Up to 12 semitones — a full octave — in either direction, in whole-semitone steps. The full range is available in the free version.

Does a pitch-shifted voice sound natural?

For the shifts singers typically need, a few semitones, the result sounds like the same song in a different key. The further you shift, the more noticeable the processing becomes, especially on vocals. For practice that rarely matters: what you need is the melody in a key you can sing.

Can I sing and play guitar along in the new key?

Yes. The whole recording moves to the new key, so you can play the song’s chords transposed by the same number of semitones and sing along at the same time. The guitar in the recording then matches what you play.

Is the key saved for next time?

Yes. The pitch setting is saved with the track, together with your loops and markers. Open the song again and it’s already in your key. Each loop can also keep its own pitch if you want to practise one section in a different key.
