1. Google has launched 'Shared Piano', its experimental tool for remote music teaching and collaboration that lets users play music together live on the web. 2. Users can play on the web app and share the link with friends to create a virtual practice space. 3. They can also switch between a piano, drums, strings, marimba, and woodwinds, among others. 4. No logins, no installations. Google identifies the different users with animal Emoji, too. 5. ‘Shared Piano’ supports a computer keyboard, a touch screen, and even a MIDI keyboard!
