Mozart is a very special musician. Although poverty often afflicts him, he always thinks that human beings are lovely. People say that he is "the heart of summer and the face of spring", and he will always be an optimist, an ideal genius full of passion and imagination. He takes the frame-up, deception and humiliation in the world lightly, believing that there will always be a bright sky and a beautiful world in front of him. At ordinary times, he is always peaceful and happy. As soon as the music touches his hands, he leaves everything behind him. Usually, when people meet him, he is always meditating, and even when he walks, he seems to be chanting something. When he sits at the table, he always fondles the corner of the table with his hand and meditates, while his lips start slightly, as if he were saying something alone. In a word, his hands and feet often keep moving, sometimes stroking something, sometimes tapping his own hat, table, chair, piano … He likes stroking anything that his hands and feet can touch. When he composes music, like writing a letter, the melody gushes from his hands. Generally speaking, whenever and wherever he is, he is thinking about his own composition. Amazingly, the prelude to Don Juan had not been written the day before the performance, but after he picked up the pen, he wrote it neatly overnight, and it was all in one go, flowing and wonderful, and all the friends in the band were shocked by his speed.
