How to slow down music without changing the pitch
To slow a song down without the pitch dropping, you need time-stretching, not a playback-speed change. GrooveCut does this right in your browser: load a track, lower the tempo, and the key stays exactly where it was — no chipmunk effect or muddy slowdown. It's free for PBT members during beta.
How to do it in GrooveCut
- 1
Open GrooveCut and load your track
Go to groovecut.pbt.dance and upload your MP3, WAV, or AAC file.
- 2
Drag the tempo control down
Move the tempo/speed slider to the pace you need — 70%, 80%, wherever the class is.
- 3
The pitch stays locked automatically
GrooveCut's time-stretch algorithm keeps the key unchanged regardless of the tempo you choose.
- 4
Loop the teaching section
Select the phrase you're drilling and turn on loop so dancers can run it on repeat.
- 5
Export or play live
Export the slowed version as an MP3, or play it straight from the browser in class.
Why it matters for dance
Beginners and barre classes can hear the counts clearly at a slower pace while the music still sounds musical and in-key — making corrections easier for the teacher and less confusing for the students.
