Johann Sebastian Bach is generally regarded as one of the greatest composers of all time. He enriched his generation, and every generation since, with his prolific ability to survey and bring together the principal musical styles, forms, and national traditions. Himself a Lutheran, he left a corpus of sacred music to cover the entire liturgical year, including Latin Masses written for the Catholic Court of Dresden, and spent much of his working life as a church music director in Germany. Though he was a highly respected organist during his lifetime, he wasn't recognized as a great composer until the early nineteenth century. Today he is considered one of the most influential ever.
