5月24日的Beyer Piano Exercises应用程序分析

When I was young, my family was very poor, but my mother wanted me to learn to play the piano like the rich children. Because I wasn't that talented, it took me 4 years to take just the first course, Bayer Piano Exercises, and my mother struggled to pay the tuition. This app is designed to help people like me learn to play the piano faster.
