Loop Player

Practice video sections in an A/B loop with adjustable speed, tabs, solo transcription, a tuner and a metronome.

Loop Player helps you practice music with YouTube videos, one section at a time, without leaving the lesson page. Open a lesson, an online course or YouTube itself. Loop Player finds the videos on the page, including players embedded in iframes. Choose Practice, set the start (A) and end (B) of the section and repeat it as many times as you need.
