In 1704 he met Andreas Werckmeister in Halberstadt know. 1707, with only 23, he was elected organist at the Church of St. Peter and Paul in Weimar, where he was befriended by Johann Sebastian Bach. Walther and Bach were distant cousins (his grandmother was a half-sister of Bach's mother). Shortly thereafter, he became a music teacher of Prince Johann Ernst, son of Duke Johann Ernst III. appointed of Saxe- Weimar and his step-sister, which gave him a high reputation.
His son Johann Christoph Walther (1715-1771) 1751 was organist at the Minster.
