These are the tones of someone attuned to the cycles of nature and the changing seasons, sensitive to the raw physicality of life, but buoyed up by the prospect of a better afterlife spent in the company of angels and angelic musicans. It is this that has prompted the book's title, describing both the physical reality - the 'Himmelsburg' in Weimar was Bach's workplace for nine formative years - and providing a metaphor for the seat of divinely inspired music.
