Crüger began studying theology in Wittenberg in 1620. In 1622, he became organist of the Nikolaikirche in Berlin.
He was a friend of Paul Gerhardt, and wrote melodies for many hymns by Gerhardt and others. Crüger composed sacred works for choral and instrumental performances, and was also a musicologist, writing about the theory and practice of music.
In 1640, Crüger edited a hymnal titled (beginning with the 1647 edition) Praxis Pietatis Melica.
