He continued his schooling at one of the most important Czech national revival movement centres, Hradec Králové, where he was a choirboy at the cathedral.
He became a fairly successful opera and singspiel composer producing more than a dozen stage works.
Among Škroup's part-time jobs was organist at the "Temple of the Israelite Society for Regulated Worship," known since the late nineteen-forties as the "Spanish synagogue."
He is best remembered today as the author of the melody for the Czech national anthem "Kde domov můj?".
Škroup's oeuvre consists mainly of Czech and German opera which gained significant local popularity.
