About
Our app is designed to provide information and parameter comparisons for people who love the piano but are not familiar with it, so that more and more people can understand the types, timbres, prices, quality, and suitable audience of pianos. We also recommend some piano teachers and share some simple piano teaching videos and basic courses, making everyone love the piano more and making life more enjoyable.
