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.
What a plain looper skips
Loop-and-slow is common; carrying it into tomorrow's session is not. Close most tools' tab and the next one starts from nothing — re-finding the same bars, re-guessing the speed you'd already reached.
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.
- Skip the manual framing when the description has timestamps. If a lesson's description lists timestamps (a lot of structured lessons do), Stairway2Fast offers them as ready-made loops the moment you add the video — tick the ones you want and they're already saved and named. No timestamps, no offer; you just frame it by hand as above.
- Let Auto speed-up do the climbing. Tell it how many clean loops to wait and how big a step to take — the default is +0.05× every three — and it raises the tempo for you as you repeat — hands stay on the guitar instead of the keyboard.
- Use the keyboard while you woodshed: space to pause, arrows to skip back and forward, shift+arrows to nudge the loop edge, number keys to jump — no mouse-hunting mid-phrase.
- Drilling a progression rather than a specific solo? Try Quick Jam. Type the chords — up to 16 bars, any key — pick a style, and a free backing band plays them back at your tempo. No video needed, and it counts toward the same practice log. See Quick Jam →
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 the same way is free too, but it does need a free account — a guest can't upload, and signing up costs nothing. Uploads stay on the device you added them on, and your library and history follow you between devices. Pro is £4.99 / €5.99 / $6 a month, or £47 / €57 / $58 a year. It adds cloud sync for your own uploads, so they open on every device you sign into, and track-splitting: a song you upload can be split into six tracks — vocals, drums, bass, guitar, piano, other — so you can solo one or mute it and play along with the rest. That only works on a file you upload; it can't reach a YouTube video's audio. Guitar's own track is newer than vocals, drums, or bass and separates less cleanly — a rough guide for studying a part, not a note-for-note isolation.
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. Guests practise straight away — loops, speeds, and history stay in that browser with nothing to sign up for. Add a free account later and everything you built moves with you automatically, synced across every device.
Is this allowed by YouTube?
Yes. Playback happens inside YouTube's own player embed, and every loop/speed control runs through YouTube's public, documented Player API — the same interface any site embedding video uses. We never download, rip, or re-host the video.
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's own speed control changes the whole video and forgets you closed the tab. This ties a loop, a speed, and a running history to the specific bars you're working — the difference between scrubbing and 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.
