It's an interactive video where you play the piano by using the timeline. Brought to you by Instrumentube. Under their profile page they've also got an electric guitar, bass guitar, upright bass and shaker. You can start your own band on YouTube!

I can imagine a world in the not-too-distant future where all human activity will be carried out on YouTube. Stay with me on this one. We'll watch entertainment videos there, play music, video-games, use it to communicate, eat, breath, dance the horizontal tango. Everything.

It'll be like the Matrix except it'll be full of 14 year-old vloggers decrying their lot in life, and fat people who can't leave the house taking the Pizza Roll Challenge who taste of heart attacks and diabetes. I can't wait.

Orange has launched a great new application, an innovative social music experience that allows you to create remixes of well known tracks using your own voice, so you can be the star. You can go it alone or by using Facebook Connect create a joint track with up to 27 friends each recording a different part. Don't panic if your voice isn't pitch-perfect, because after recording the song you can change the pitch and auto-tune your best efforts.

It's easy to use, you can record yourself rocking out by using your PC microphone or by dialling a number on your mobile, then share your popstar glory with the world via the usual social networking suspects.

Orange RockCorps is a music-led volunteer programme. By volunteering to help out within your local community you can earn yourself a free ticket to an exclusive gig, a gig which you can't buy a ticket to. Check out how to register and how to start recording your own remix.
