Practice the exact phrase that needs work. Find a song on YouTube, mark the section, loop it, and slow playback down for focused repetition. Save and edit sections for later sessions, share them with someone you are teaching, and browse curated or community song lists. Tune Looper is built for musicians, transcription and learning tricky passages without constant scrubbing. Works in the browser, with a free plan and optional paid upgrades. Also available on Android.
