## What it is
AutoPiano is a free online virtual piano application built with HTML5 technology, letting users play piano and many other instruments via their computer keyboard, mouse, or an external MIDI keyboard. It includes multiple instrument sounds, key-mapping layouts, sheet creation tools, and mobile/mini-program versions.

## Use cases
- play a virtual piano in the browser
- practice piano using my computer keyboard
- connect a MIDI keyboard to a web piano app
- create keyboard sheet music for songs
- play different instrument sounds online
- learn piano notes and key mappings
- relax by playing music online

## When to choose
- you want a free browser-based piano with many instrument sounds
- you need MIDI keyboard support in a web app
- you want to study the source code of an HTML5 audio application

## When to avoid

- you need a native desktop piano application
