It's such a pain asking real people for help, especially when it comes to musical instruments. What, you know what a diminished seventh is? YOU THINK YOU'RE BETTER THAN ME??

Well scream no more, wannabe fretmasters. A website called nowplayit.com will show you how to play your favourite songs (uh, KT Tunstall is your favourite, right?), possibly even with a tutorial from the original artist.

Paul McCartney, Supergrass, Blur and the aformentioned Tunstall are among the artists who contribute to the site, with a full tutorial of at least 15 minutes costing £3.99. You can also purchase "lite" tutorials, or versions without sparkly celebs, for slightly less.

The videos can be put on your iPod so you can practise on the train, if you're one of those annoying people who actually wanders around with your geetar.

As Mashable pointed out on the site's launch a few months ago, it's actually surprising to see that the site hasn't gone the whole hog for the seemingly-obligatory social networking angle. When you click on the "community" tab you reach a rather underpopulated forum page, which does seem like a trick missed - I'd have thought that it might be a way for people looking to form bands to make contacts, or a way for friends to track each others' progress as they try and master certain tracks.

But then most guitar virtuosos forgo human relationships so they can spend more time with their instruments, right?
