Piano Prime is a free and very easy-to-use piano app for browsers.

You can choose to play songs using the built-in keyboard, or by using the app's mouse or keyboard.

This app can be useful for both learning and practicing piano.

It is recommended to use a device with a screen, such as a tablet or a smartphone, to make the app more immersive.

There are a total of 52 keys, but only 20 of them are visible at first.

The number of keys that are visible can be adjusted from the options page.

You can record your desired songs and replay it at any time.

You can also change the settings to hide the keyboard at the top.

The keyboard can be hidden by toggling the switch.
