This modern neo-classical piece by the French composer Yann Tiersen is a clever piece which builds upon a recurring pattern in the left hand. The four sections continuously develop the themes until, by the end of the piece, you have been carried on a musical adventure while never leaving the underpinning sea of the left hand's repeating pattern. The lesson starts with a full demonstration of the song followed by a detailed "by ear" lesson demonstrating and explaining every phrase and note of the song. This is a fast way to learn this moving piece while memorizing it at the same time.
