The ONE Smart Piano App is FREE to download and use with your iOS or Android mobile devices (including your tablets and smartphones).

And, without the app, the piano works like any other digital piano in that you simply turn it on and play!

All of the public domain content is for free – over 2000 classical masterpieces. And the systematic piano tutorial from our partner Hoffman Academy is also for free.
Only the copyrighted content, mostly pop music, is for sale from $0.99.

Will I become too dependent on the LED lights?2020-06-18T07:25:23+00:00

Our system supports learners by helping individuals play through songs first to build interest, then adding on additional skills such as reading music, hand positions, and musical expression. Muscle memory is also a big part of playing piano, so we try to help individuals find their own musical expression rather than focusing on mapping notes to keys right at the start. With our system, you’ll find faster progress in your initial learning even without the sight-reading skills. When you’re ready to play independently, you can turn off the LED lights.

How do I register for The ONE Smart Piano app?2020-06-18T07:23:14+00:00

Who founded the company?2020-06-18T05:20:23+00:00

Ben Ye and Yusha He are the co-founders of The ONE Music Group. Ben is a serial entrepreneur with several exits, while Yusha is a former piano teacher!

It was inspired by an 8 years old boy, Bob, who quit piano lessons shortly after starting. As Bob’s father, a serial software entrepreneur, Ben Ye couldn’t find an existing solution to get his son excited about music learning, so he created a solution to make learning to play the piano as fun as playing an iPad game. The little boy was so excited and jumped on it and learned to play the song “Twinkle Twinkle Little Star” in just 20 minutes all by himself using the smart piano prototype (which later evolved into the world’s first and only upright, Apple MFI-certified digital piano).


Does the keyboard have weighted keys?2020-06-18T06:15:10+00:00

The ONE Light keyboard has touch-sensitive keys, not hammer-action weighted.

But The ONE Keyboard Pro, Keyboard Pro Essential, and The ONE Upright Smart Piano have Hammer-Action keys, they’re all full weighted keys, and you’ll be happy to experience that!

Can I plug the keyboard into a computer?2020-06-18T06:12:25+00:00

Are there certain headphones that work with this?2020-06-18T06:10:03+00:00

No, it doesn’t need certain headphones, it supports all standard 3.5mm jack headphones or external microphones, so that you can sing while you play!
