friend of Beethoven. The diagram represents the wooden framing of such
an instrument. We gather from Burney's contributions to "Rees's Cyclopaedia," that after the arrival of John Christian Bach in London, A.D. 1759, a few grand pianofortes were attempted, by the second-rate harpsichord makers, but with no particular success. If the workshop tradition can be relied upon that several of Silbermann's workmen had come to London about that time, the so-called "twelve apostles," more than likely owing to the Seven Years' War, we should have here men acquainted with the Cristofori model, which Silbermann had taken up, and the early grand pianos referred to by Burney would be on that model. I should say the "new instrument" of Messrs. Broadwood's play-bill of 1767 was such a grand piano; but there is small chance of ever finding one now, and if an instrument were found, it would hardly retain the original action, as Messrs. Broadwood's books of the last century show the practice of refinishing instruments which had been made with the "old movement." [Illustration: Fig. 1.] Burney distinguishes Americus Backers by special mention. He is said to have been a Dutchman. Between 1772 and 1776, Backers produced the well-known English action, which has remained the most durable and one of the best up to the present day. It refers in direct leverage to Cristofori's first action. It is opposite to Stein's contemporary invention, which has the hopper fixed. In the English action, as in the Florentine, the hopper rises with the key. To the direct leverage of Cristofori's first action, Backers combined the check of the second, and then added an important invention of his own, a regulating screw and button for the escapement. Backers died in 1776. It is unfortunate we |
