Virtual Piano Trainer is a free Android application developed by Alexander Mishkovets, designed to help users learn how to read sheet music and play piano notes. With this app, you can practice and improve your music reading skills, regardless of your level of expertise.

One of the most notable features of Virtual Piano Trainer is the ability to display two or four octaves simultaneously.

Another interesting feature of Virtual Piano Trainer is the screensaver, which includes a built-in MIDI player that plays beautiful classical music pieces during your break. Overall, Virtual Piano Trainer is a useful tool for anyone looking to improve their music reading skills and learn how to play the piano.
