Midomi

Midomi lets you search for music with your voice. Plug in a microphone, sing a bit, and this site will search in its database and hopefully, name that tune. Visit www.midomi.com

I tested out the system with a Carpenters song and amazingly, Midomi got it right first time.

Instead of matching my rendition of "Close to you" with Karen Carpenter's version, it was matched with recordings by other Midomi users, who all seemed to go flat in the same places as me! I had no idea that bad singers were that predictable.

You can also build an online profile, hook up with fans of the same kinds of music, and rate or comment on each other's songs.

Like all social networks, Midomi works on the strength of its users. So the more people sing into it, the more we will all get out of it and - believe me - this site is has only just begun
