How do I slow down a YouTube video?
Quick answer
On YouTube, click or tap the gear icon, choose Playback speed and pick a rate below Normal, such as 0.75 or 0.5. On RepeatWatch, drag the speed slider anywhere from 0.25× to 2× in 0.05 steps, and turn on the speed trainer to raise the speed gradually as you practice.

Does slowing down a YouTube video change the pitch?
No. YouTube keeps the original pitch when you change speed, so a song at 0.75× sounds slower but stays in the same key. That makes slowed playback useful for learning music by ear.
What is a speed trainer?
A speed trainer plays a loop slowly and raises the speed a little after a set number of repeats, for example by 0.05× every 3 loops, until you reach your goal. It's a common way to build up to full tempo without rushing.
How slow can a YouTube video go?
The YouTube player goes down to 0.25×, a quarter of normal speed, and up to 2×. Speeds between about 0.5× and 0.85× are the most useful for practice because the audio stays clear.
Frequently asked questions
Can I speed up a YouTube video beyond 2×?
Not in the embedded YouTube player that RepeatWatch uses, which tops out at 2×. Most practice and listening happens between 0.5× and 1.5×.
Does RepeatWatch remember my speed?
Yes. RepeatWatch saves the speed with each video on your device, and loop links include the speed, so the person you share a link with hears the same tempo.
What are the keyboard shortcuts for speed on YouTube?
On youtube.com, press Shift and the greater-than key to speed up, or Shift and the less-than key to slow down. On RepeatWatch, press minus to slow down and equals to speed up.
