Bass Players Know the Struggle
Bass buried in the mix
Low frequencies get swallowed in full-band recordings. Slowing down makes the bass line pop out of the mix so you can actually hear what's being played.
Fast runs are impossible to parse
16th-note funk lines, rapid slap patterns, and chromatic runs blur together at full speed. At 0.5x or 0.25x, every note becomes clear.
Groove and timing are hard to catch at speed
Feel the pocket. Slowing down reveals the micro-timing, ghost notes, and subtle rhythmic choices that make a bass line groove.
How It Works
Paste a YouTube URL
Find a bass cover, isolated bass track, lesson, or any song on YouTube. Paste the link into PracticeLoop.
Set your loop points
Mark the start and end of the passage you want to work on. The tool loops just that section automatically.
Slow it down and practise
Drop the speed to hear every note. Practise the passage on repeat, then gradually bring it up to tempo.
Built for Serious Practice
Speed Control 0.25x -- 2x
Fine-grained slider from quarter speed to double time. Use presets or dial in the exact tempo you need.
AB Looping
Set precise start and end points. The section repeats until you nail it. No more scrubbing back and forth.
Saved Loops
Name and save your loops for each video. Come back tomorrow and pick up exactly where you left off.
Keyboard Shortcuts
Space to play/pause, [ and ] for loop points, L to toggle loop, arrows to seek. Hands stay on bass, eyes stay on screen.
Progressive Speed Training
Start slow and auto-increase speed after a set number of loop reps. Build muscle memory gradually -- just like a real teacher would guide you.
What Bass Players Use It For
Learning bass lines
Slow down covers and isolated tracks to transcribe note-for-note. Build muscle memory at a comfortable tempo before speeding up.
Funk and slap bass patterns
Thumb pops and hammer-ons fly by at full speed. At 0.5x you can break down every slap, pop, and dead note in the pattern.
Jazz walking bass
Hear the note choices, approach tones, and chromatic passing notes that make a walking line swing. Slow it down to study the harmony.
Transcribing bass solos
Jaco, Victor, Marcus -- their solo passages demand repeated listening at reduced speed. Loop and slow down to catch every inflection.
Frequently Asked Questions
Can I slow down bass lines on YouTube without downloading anything?
Yes. PracticeLoop runs entirely in your browser. Paste any YouTube URL, set your speed from 0.25x to 2x, and start practising immediately. No downloads, no installs, no account required.
How slow can I play a bass line?
PracticeLoop supports speeds from 0.25x (quarter speed) up to 2x. At 0.25x you can hear individual notes in even the fastest slap bass runs or walking bass lines.
