tone.min.js
The single-page web app has been created and saved to `index.html`. It includes a playable piano keyboard that uses the `tone.min.js` library to synthesize notes with an ADSR envelope. The keys can be played using the mouse and the specified computer keys (a, s, d, f, g, h, j, k, l). You can now open `index.html` in a web browser to test the piano keyboard.
