Music practice gear for looping

Three things make looping music practice easier: a clip-on tuner, closed-back headphones and a phone stand. Slow loops show up small problems, like a string slightly flat, a bass line you can’t hear or a screen you keep reaching for, and these three fix them without changing how you practise.

Do I need any of this to loop a video?

No. RepeatWatch is free and works with what you have. Start with the guide: how to learn a song from youtube.
