Following an old tradition, in the 17th century German composers used to open their sacred compositions with a short instrumental introduction, which they usually called “sonata” or “sinfonia”. Johann Sebastian Bach (1685-1750) continued this tradition: his instrumental introductions were magnificent virtuosic sinfonias with concertato instruments that introduced the splendid atmosphere of the court chapel into the world of municipal church music, reminding listeners that their composer was the former kapellmeister of the Prince of Anhalt-Cöthen, a title he still used. This new recording presents six Sinfonias for obligato organ, from the cantatas BWV188, 169, 49, 146, and 35. They are played by Takashi Watanabe, winner of the Early Music Prize of Japan, student of Bob van Asperen and continuo player in many prestigious Early Music groups. The Ensemble Cordia, led by Stefano Veggetti, has made several highly acclaimed recordings for Brilliant Classics, featuring works by Platti, Wranitsky, Telemann.
