This recording is dedicated to the memory of Jürgen Ammer, the man who built the two copies of harpsichords heard here, both models from Bach's environment: one after Harraß from Thuringia with a 16' stop, the other after an instrument by Zacharias Hildebrandt, who was Bach's personal instrument maker in Leipzig. It was Ammer who proved that the Harraß harpsichords are authentic (there were doubts because of the 16' stop, unfamiliar to most musicologists), and who discovered the only surviving Hildebrandt harpsichord near Warsaw. When he died unexpectedly last summer we lost the leading expert on Thuringian and Saxon harpsichords - he was an interesting and knowledgable man (I was introduced to him a few years ago at a concert where two of his instruments were played and had a nice conversation with him). I learned a lot from him within an hour. I wish I could have attended the concert after which this recording was made ..... and that he had lived longer to finish writing his book about Bach's instruments.
