In 1783 he took his father's place in the Munich orchestra and composed his third German opera.

He married a singer and enjoyed an active career in opera that led to his appointment as deputy Kapellmeister in Munich in 1798.

After his wife's death he returned to Mannheim and, in 1807, was appointed Kapellmeister in Stuttgart, where he met Weber.

Danzi wrote some eighteen stage works, generally in the form of German Singspiel, with its mixture of music and spoken dialogue.

Other forms used include melodrama and grand opera in a version of the early 18th century libretto by Apostolo Zeno, Iphigenie in Aulis.

Danzi wrote sacred and secular choral music, Masses, oratorios and cantatas.

His songs and canzonettes are in contemporary style, but no longer regarded as an important part of German song tradition.

In orchestral music Danzi was similarly prolific, contributing mainly to the Sinfonia concertante and concerto repertoire.

Danzi's chamber music includes sextets, quintets, quartets and trios, some for strings, some for wind instruments and some for a combination of the two.

His duo sonatas show a similar variety in their instrumentation.

These works are generally in a style that reflects his own early experience in Mannheim and the influence of his teacher Abt Vogler, with whom Weber also studied.
