Question: Where is Baroque composer Adam Krieger from? Passage:Johann and his older brother Johann Philipp came from a Nuremberg family of rugmakers. Neither are related to Adam Krieger, another Baroque composer. Johann studied with Heinrich Schwemmer (teacher of Johann Pachelbel) at St. Sebaldus, and sang in the choir there for several years. From 1661–68 Krieger studied keyboard playing with Georg Caspar Wecker. His older brother's development was different, for Johann Philipp studied with a Froberger pupil, Johann Drechsel. However, for about a decade from 1668 the two brothers' lives shared the same course. In 1671 both Kriegers studied composition at Zeitz. In 1672 Johann Philipp moved to Bayreuth and became court organist there. He very quickly rose to the rank of Kapellmeister, and was succeeded as court organist by Johann. In 1677 Johann Philipp was employed as court organist at Halle, and Johann soon became chamber musician at Zeitz, a city some 30 miles away. He then attained the position of Kapellmeister at Greiz (a further 30 miles south from Zeitz).
