Slow down YouTube videos for guitar practice
Paste any YouTube guitar lesson, solo, or cover into Stairway2Fast and it becomes a practice loop: drag two handles around the hard bars, drop the speed to 0.75× or 0.5× — the pitch stays put — and it repeats until your fingers get it. Free, in your browser, no signup.

How it works
- Paste a YouTube link. Any lesson, solo breakdown, or cover — if it plays on YouTube, it loops here, through YouTube's own player.
- Frame the hard part. Two handles on the timeline mark the exact bars — the fast run, the tricky change, the bend you keep missing. The loop stays locked while you play along.
- Drop the speed. 0.25×–2× in steps, pitch unchanged, so the notes sound like notes instead of mud. Climb back up one notch at a time as it gets clean.
The part other loopers don't do: it remembers
Plenty of tools can loop and slow a YouTube video — and then forget you were ever there. Close the tab, and tomorrow you're re-finding the timestamp, re-setting the speed, re-doing yesterday's discovery work.
Stairway2Fast keeps the record. Every video remembers its loops (name them — "solo bars 3–4", "chorus riff") and the speed you left off at. Every minute of practice logs automatically against the video and the section. After a couple of weeks you can see the thing that actually keeps you practising: the day you finally broke 0.9× on the solo you started at 0.6×. Streaks, a practice stairway, per-song history — earned, not typed in.
Guitar-specific tips
- Loop smaller than you think. Two bars at 0.6×, clean, beats eight bars at
0.8×, sloppy. The handles go down to fractions of a second.
- Name your loops. A lesson video with "intro riff", "verse pattern", "solo" saved as named loops turns a 20-minute video into a practice menu — one tap puts you back on the section at your last speed.
- Let the speed ramp work. Set a start and target speed and the loop climbs automatically as you repeat — hands stay on the guitar instead of the keyboard.
- Use the keyboard while you woodshed: space to pause, arrows to nudge, number keys to jump — no mouse-hunting mid-phrase.
Free vs Pro, honestly
Everything above — looping, slow-down, named loops, all the practice tracking and stats — is free, with no account. Uploading your own recordings to practise is free too — they stay on the device you added them on. Sign up (also free) and your library and history sync across devices. Pro (£4.99/$6 per month) adds the cloud layer: your uploads on every device, plus track-splitting — split an uploaded song into its instrument tracks to study a part or play along with the band.
FAQ
Does slowing down change the pitch?
No. Playback uses pitch-preserving time-stretch, so an A stays an A at 0.5×. That's the whole point for practice — you're training your ears and fingers on the real notes, just slower.
Do I need an account?
No. Open the app and practise as a guest — loops, speeds, and history are kept in your browser. Create a free account when you want it synced across devices; everything migrates automatically.
Is this allowed by YouTube?
Yes. The video plays in YouTube's own embedded player, and speed/loop control uses YouTube's public, documented player API. Nothing is downloaded, ripped, or re-hosted.
Can it slow down any YouTube video?
Any video that allows embedding (nearly all lessons and covers do). If a channel has disabled embeds, YouTube blocks playback outside youtube.com — no looper can change that.
What speeds are available?
0.25× to 2× in steps. For most guitar work the useful band is 0.5×–0.9×: slow enough to be accurate, fast enough to keep the feel.
How is this different from YouTube's built-in speed setting?
YouTube can slow a whole video; it can't loop a section, remember your spot, or tell you anything about last week. Here the loop, the speed, and your history live with the video — that's what turns watching into practising.
Nail the fast part. Open a lesson, frame the hard bars, slow it down — and watch yourself climb back to full speed, week after week.
