Below you will find links to the pages of colleagues and friends working on similar subjects with whom I have had many an exchange on my favourite topics, as well as colleagues who helped me with photography and recording.
Elam Rotem and his wonderful website earlymusicsources.com
Maria Luisa Baldassari with her fantastic collection of pictures of keyboard handpositions
For most of the photographs: Ivan Kitanovic
I would also like to thank my former students from whom I learnt so much. Many of them became wonderful colleagues.
I own two harpsichords by Joel Katzman, one inspired by a small Ruckers instrument (a=415) and the other inspired by a Trasuntino instrument from 1531 (a=348). I thank Sonja Leipold for letting me record some videos on her 4' spinettino.
