Guides

How do I slow down a song without changing the pitch?

Choose the song above and set the speed from 50% to 200%. The key stays the same. Listen, then download the result as a WAV.

Slow songs down to learn them

Learning a fast solo or a tricky verse is easier at 60% to 75%. Work up to full speed in small steps.

Change the speed and the key together

Set the pitch too if you need the song in another key at the new speed.

Questions

Can you change the tempo without changing the pitch?

Yes. The tempo and the pitch change separately.

How slow can I go?

Down to half speed, or up to twice as fast.

Does slowing a song down lower the quality?

Very slow speeds can soften sharp sounds such as drums, but voices and instruments stay clear down to about 70%.
