Why I Built loopAB
I spent countless hours in high school and university practicing the trumpet. Now I'm learning violin alongside my daughter (who also plays piano), and I enjoy whistling as well.
Through all these years, I've come to believe that playing an instrument is a craft of mastery—there are no secrets, no shortcuts. It's about practicing slowly, playing each note solidly, and gradually building up speed.
One day I discovered how useful the loop function could be for practice. But existing tools weren't quite right. So I built loopAB—the YouTube looper I wished existed.
“Practice slowly, play each note solidly, and build up speed gradually. There are no secrets—just patient, deliberate practice.”
