YouTube bar-by-bar practice tool
Barlooper - Loop any YouTube video by bar and practice tough sections one measure at a time.
Short, evidence-grounded notes on bar-by-bar practice, slow practice, and looping YouTube tutorials.
ArticlesPaste a YouTube link, set the BPM, and BarLooper splits the track into bars. Tap any bar to loop it, slow it down, and master the part you keep missing.
Paste the URL of the song you want to practice and press 'Load video'.
Enter the song's BPM and use the slider to align the first downbeat.
Press 'Split into bars' — the track is divided into bar sections automatically.
Tap a bar section to loop it, then drop the speed to 0.5–0.75× until it locks in.

Yes. You can change the playback speed between 0.5× and 2× while looping a bar or a custom time range.
