Beethoven, as a musician, is not afraid of powerful people and resolutely defends his personality and dignity. "Your highness, you became a prince because of your background, and I, relying on my own talent and efforts, became a musician. You know, there will be hundreds of princes in the world, and Beethoven has only one! " Beethoven used this letter to express his backbone and dignity as a musician to the nobles of the whole upper class. Nowadays, the phrase "there is only one Beethoven" has become synonymous with the dignity and personality of almost all artists.
