Okay, so they won't blow your mind, but they WILL teach you how to play the 12 Bar Blues. This is the first stage, so would be aimed at more of a beginner pianist. Using these 3 tutorials, by the end of them you'll be able to play a simple 12 Bar Blues pattern in the key of G with both hands.
The first lesson focuses on learning the the different chord patterns, correct fingering and structure in the right hand.
Here is the correct structure and counting patterns to help you.
In this lesson I'll teach you the left hand part.
And finally in this tutorial I'll show you how to put both hands together.
I hope you've learnt from my lessons, and can now riff along the 12 Bar Blues. Stay tuned for the next stage where I take things to the next level.
