His main positions were Kantor of the Johanneum Lateinschule and Musical Director of the five main churches of the city.
He had been living in Hamburg for about 14 years when he wrote Allein Gott in die Höh sei Ehre , by which time he was securely embedded as a most prominent and influential figure in Hamburg society.
He was also director of the Gänsemarkt opera house, where he mounted performances of his own operas, and those of other composers, particularly Handel’s, to which he added some of his own numbers. He founded a collegium musicum in Hamburg, and also one in Leipzig. It was originally intended that the collegium would give one concert a week during the winter season, but the public demanded two. On top of this he published his own music, wrote poetry and was corresponding agent for the Eisenach court, collecting news from across northern Europe.
Apart from a natural workaholic tendency, some of his workload may have been driven by the need to service the massive gambling debts his 2nd wife incurred.
