Whilst searching for piano tutorials to publish on the blog I came across the OnlinePianist.com
This is a great resource for pianists of all levels who want to learn how to play actual songs and pieces of music that aren’t just in the public domain.
There is an extensive library of songs in many styles with literally hundreds of examples.
The songs are not exactly tutorials but if you go to the site you will see the innovative method they have used to offer their tutorials.
There is a keyboard onscreen which shows you the notes of the song as they are being played. At first glance it appears to be a video but actually it is more like an interface. The good thing is that you are able to adjust the speed of the playback and start and stop it. 
This way you can watch and copy in slow motion as you learn. Another really useful feature of the interface is that you can choose to split the performance up and view either the left hand on its own, the right hand or both hands together.
The basic interface is free and you get access to the hundreds of songs and pieces of music available however after a couple of plays you need to sign up via Facebook to retain access. There is a piad version as well that offers some advanced features.
