Michael Praetorius based his chorale concertos on motet style.
Explanation:
Michael Praetorius was a German composer from the early period of Baroque music.
He is well known for his church music, and was also a music theorist. His three-part treaty "Syntagma musicum" can be seen as an encyclopedia of the music theory and practice of that time. The first part deals with church music and contains a wealth of quotes from older sources; the second part gives an overview of the usual musical instruments.
Praetorius uses polyphony according to the Italian motet style and applies this to German music. Praetorius learned the Italian motet style from Giovanni Gabrieli.
