Mozart is considered one of the greatest composers of European classical music, having written an astonishing number of works in almost every musical genre during his short life. He began touring as a child prodigy(神童)and went on to a career in Vienna that was fraught(に満ちた)with illness and financial difficulties. Underappreciated(正当に評価されない)in his own time, his gifts for clarity, balance, and chromatic(鮮やかな色彩の)harmony have since inspired countless composers.
