BACH, Carl Philip Emanuel, the second son of Johann Sebastian Bach, was by far the most remarkable of the eleven brothers, not only for his peculiar genius and originality, but also for the great influence which his compositions exercised on the forms and style of later instrumental music. His style, full of novelty and elegance, was that which Haydn and Mozart studied attentively, and carried to perfection by giving it greater breadth of development. He was born at Weimar on the 14th of March 1714, and died at Hamburg on the 14th of December 1788. His compositions, vocal and instrumental, are numerous. Many of them are still unpublished. (G. F.
