## What it is
A browser-based piano application built with the Omi framework (JSX + Web Components) that lets users play songs using eight keyboard keys. It maps keyboard presses to piano note samples and includes built-in song sheets like 'Dandelion's Promise' and 'The Moon Represents My Heart'.

- play piano with my computer keyboard
- play a song on a virtual piano in the browser
- learn how to build a web audio app with Omi
- demo project for Omi framework and Omil SFC loader
- play Dandelion's Promise on keyboard
- keyboard-to-note mapping example

## When to choose
- you want a fun browser piano playable with the keyboard
- you want a small example app showcasing Omi, Web Components, and Proxy-based component communication
- you want a lightweight music toy to deploy on a static page

## When to avoid
