Final answer:
The composer Ludwig van Beethoven continued composing even after he went completely deaf.
Step-by-step explanation:
The composer Ludwig van Beethoven continued composing even after he went completely deaf. His deafness began around age 30 and progressively worsened over time, eventually leaving him completely unable to hear. Despite this profound challenge, Beethoven continued to create music and compose some of his greatest works, including his Ninth Symphony and late string quartets. His ability to compose without hearing the music is a testament to his immense talent and perseverance.
