The 'Sinfonia' is the opening of the second part of the 'Christmas Oratorio': 'Am zweiten Weihnachtsfeiertage'. This romantic piece of music was in the tradition of the shepherd music as set by Italian composers as Corelli , Manfredini and Tartini. Typical for the 'Pastorale' as a genre was the 6/8 or 12/8 beat and the 'siciliano' rhythm.
