You’re Not Mozart
Pianos are probably the most inviting musical instrument in existence. Almost everyone has a longing to sit at a piano bench and be able to achieve beautiful, whimsical sound with a glide of their fingers. Of course, learning to play the piano takes years of discipline and determination, of which many people will never put forth.
So rather than performing a masterpiece at the piano, or even something as simple as “Twinkle, Twinkle, Little Star”, most people sit at the piano and… make noise. This teacher would prefer to reserve the piano for the Mozart like students of the group, and she knows that they are few and far between.
