From the Ground Up (Beginners and Early Novices)
This piece is gargantuan - you will likely play louder than you’ve ever played while you learn this piece. So keep the following in mind:
While learning this piece, you may feel an impulse to play loudly right out of the gate. Because after all, the piece requires it. Fight this urge. Instead, learn the piece at a moderate to moderately-quiet level. If you play the piece loudly prematurely, before you know the notes, movement, rhythms, etc well, your hands will become tired and tense very quickly. And worse still, if you do this continuously, the tension will become habitual without you noticing and you will end up tense and tired even when a piece is learned very well. Increasing the volume of your playing should come once the notes are learned well. Then adapting your technique to louder playing is much easier and you will be able to focus on the next most important technical element: effective and free sound production.
A huge sound on the piano should be created without any pushing or deliberate force. Instead, it should created with the free use of arms weight and body weight. The wrist should remain supple and the arms free. To dive deeper into sound production and its principles, watch this video from the Blueprint lecture:
