You are Dmitri Shostakovich!
Congratulations! You are a shy, nervous, unassuming, fidgety, and stuttery little person who began composing the same year you started music lessons of any sort. You wrote the first of your fifteen symphonies at age 18, and your second opera, "Lady Macbeth of the Mtsensk District," when you were only 26. Unfortunately, Stalin hated the opera, and put you on the Enemy Of The People List for life. You nevertheless kept composing the works you wanted to write in private; some of your vocal cycles and 15 string quartets mock the Soviet System in notes. And you somehow were NOT killed in the process! And Harry Potter(c) stole your glasses and broke them!
