Johann Bernhard Bach (1676-1749), was a German composer, and cousin of J. S. Bach. He was born in Erfurt, and his early musical education was by his father, Johann Aegidus Bach. He took up his position as organist in Erfurt in 1695, and then took a similar position in Magdeburg. He replaced Johann Christoph Bach as organist in Eisenach, and also as harpsichordist in the court orchestra in 1703. Most of his musical output has been lost, but amongst his surviving music there are four orchestral suites. It is known that J. S. Bach had individual parts prepared for performance by his orchestra. His musical style has been described as being similar to that of Telemann.
The surviving orchestral suites (overtures) are as follows:
Suite No. 1 in G minor
Suite No. 2 in G major
Suite No. 3 in E minor
Suite No. 4 in D major
and they are thought to have been written before 1730.
