What is the first name of Johann Wilhelm's father?
On 2 March 1714 Bach was appointed Konzertmeister (concert master) of the Weimar Hofkapelle (court chapel) of the co-reigning dukes Wilhelm Ernst and Ernst August of Saxe-Weimar. The position was created for him, possibly on his demand, giving him "a newly defined rank order" according to Christoph Wolff.From 1695, an arrangement shared the responsibility for church music at the Schlosskirche (court church) between the Kapellmeister Samuel Drese and the Vize-Kapellmeister Georg Christoph Strattner, who took care of one Sunday per month while the Kapellmeister served on three Sundays. The pattern probably continued from 1704, when Strattner was succeeded by Drese's son Johann Wilhelm. When Konzertmeister Bach also assumed the principal responsibility for one cantata a month, the Kapellmeister's workload was further reduced to two Sundays per month.The performance venue on the third tier of the court church, in German called Himmelsburg (Heaven's Castle), has been described by Wolff as "congenial and intimate", calling for a small ensemble of singers and players. Performers of the cantatas were mainly the core group of the Hofkapelle, formed by seven singers, three leaders and five other instrumentalists. Additional players of the military band were available when needed, and also town musicians and singers of the gymnasium. Bach as the concertmaster probably led the performances as the first violinist, while the organ part was played by Bach's students such as Johann Martin Schubart and Johann Caspar Vogler. Even in settings like chamber music, Bach requested a strong continuo section with cello, bassoon and violone in addition to the keyboard instrument.
