Violinists Know the Struggle
Intonation issues are invisible at full speed
When passages fly by, slightly flat shifts and out-of-tune double stops slip past unnoticed. Slowing down reveals every tuning issue so you can correct it before it becomes a habit.
Position shifts are hard to learn at tempo
Moving from first to fifth position in a fast passage requires precise muscle memory. At 0.5x you can hear and see exactly where the shift lands, building accuracy before speed.
Bow technique disappears in fast passages
String crossings, spiccato, legato transitions, and detache all blur together at performance tempo. Slow it down and every bow stroke becomes clear enough to study and replicate.
How It Works
Load the YouTube video
Find a violin masterclass, concerto performance, etude demonstration, or any piece on YouTube. Paste the link into PracticeLoop.
Slow to 50% speed
Drop the speed slider to 0.5x. At half speed, every note, shift, and bow change becomes clearly audible while pitch stays correct.
Focus on intonation
Listen carefully for pitch accuracy. Slowing down exposes tuning issues that hide at full tempo, especially in high positions and during shifts.
Work on bowing
Study the bow technique -- string crossings, spiccato, legato, detache. At reduced speed you can see and hear exactly how the bow moves on the string.
Increase speed gradually
Once you can play the passage cleanly at 0.5x, move to 0.6x, then 0.75x, and work your way up. Use AB looping to repeat the section automatically.
Built for Serious Practice
Speed Control 0.25x -- 2x
Fine-grained slider from quarter speed to double time. Pitch stays correct at all speeds -- essential for violin intonation work.
AB Looping
Set precise start and end points on any passage. Loop a tricky shift, a fast run, or an entire cadenza section on repeat.
Saved Loops
Name and save loops like "Bar 24 shift" or "Cadenza opening". 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. Keep your hands on the violin, not the mouse.
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 Violinists Use It For
Studying intonation and shifting
Slow down concerto passages to hear every shift landing. Compare your intonation against the recording note by note. Build accuracy in high positions at a comfortable tempo.
Mastering bow technique
Spiccato, ricochet, sautille, col legno -- advanced bowing techniques are impossible to follow at performance speed. At 0.5x every stroke is clear enough to study and replicate.
Learning vibrato styles
Arm vibrato, wrist vibrato, finger vibrato -- each sounds different. Slow down recordings of great violinists to study the speed, width, and character of their vibrato on each note.
Transcribing and ear training
Work out fingerings, bowings, and ornaments from recordings. Loop bar by bar at 0.25x to catch every grace note, trill, and articulation detail.

Frequently Asked Questions
Can I slow down violin performances on YouTube?
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. It works with violin masterclasses, concerto performances, etude demonstrations, and any other violin content on YouTube.
Does slowing down affect the pitch of the violin?
No. PracticeLoop uses YouTube's built-in playback engine, which adjusts speed without changing pitch. The violin stays at concert pitch at any speed. This is essential for violin practice since you need accurate pitch reference to work on intonation.
How do I loop a specific violin passage for practice?
Use the AB loop feature to mark exactly where the passage starts and ends. Click Set Start when the section begins, then Set End where it finishes. PracticeLoop will repeat just that section continuously. You can also save named loops to come back to later.
Is PracticeLoop free for violin practice?
Completely free. No account, no trial period, no hidden fees. PracticeLoop is a free browser-based tool for musicians. Speed control, AB looping, and saved loops are all included at no cost.
