Beethoven was deaf but it was his physical ear that didn’t work. But he was not born deaf and during his childhood and youth he trained his inner ear intensively. Inner ear is just in your mind, but is the most powerful tool a musician can have. The other very important thing that Beethoven had until the end of his days was his extremely solid understanding of ‘harmony, melody, orchestra, piano, and sound itself. Maybe he was not the author of the concept of paining, but he was one of the first musicians who experimented with the position of the instruments considering low and high pitches as well as focus and body. Beethoven was the loneliest man in the world, condemned to be locked in his own mind, unable to hear his own prodigious creations. Despite this, Ludwig van Beethoven was a crucial figure in the transition between the ‘classical and romantic eras’ in classical music. He remains one of the most recognised and influential musicians of this period, and is considered to be one of the greatest composers of all time. He was provided with an amazing mind and strength of character which never betrayed him .
