St. Bartholomeus Kirche, Dornheim. At St. Bartholomew Church in Dornheim, Germany, where composer Johann Sebastian Bach married his first wife Maria Barbara, renowned Dutch cellist Anner Bijlsma performs the composer's Cello Suite No. 1 in G major, BWV 1007. It is likely Bach wrote his collection of six Suites for unaccompanied cello during the years 1717-1723. His cello suites are an essential part of the cello repertoire, highlighting the instrument's manifold polyphonic possibilities. As customary in a Baroque suite, each movement is based on a dance type. Bach's Suite No. 1 opens with a prelude, and is followed by six dance movements, divided over five sections: an allemande, a courante, a sarabande, two minuets, and a final gigue.
