The origin of Bach’s Goldberg Variations is as follows:
The ambassador to Saxony, often visited Leipzig. Among his servants there was a talented young man, Johann Gottlieb Goldberg – a harpsichordist (Cembalist) who was a pupil of Wilhelm Friedemann Bach and later of Johann Sebastian Bach himself.
The count had been suffering from insomnia and ill health and Goldberg, who also lived there, had to stay in the room next door to soothe his master’s suffering with music. Once the count asked Bach to compose some keyboard pieces for Goldberg, pieces of mellowness and gaiety that would enliven his sleepless nights.
Bach decided to write a set of variations, a form that prior to this, hadn’t interested him much. Nevertheless, in his masterly hands, an exemplary work of art had been born. The count was so delighted with it, he called them ‘my variations’. He would often say: ‘My dear Goldberg, play me one of my variations.’
Bach had probably never been so generously rewarded for his music. The count gave him a golden goblet with a hundred Louis d’Or!”
