A translation of Jean Denis's Treatise on Harpsichord Tuning (1643/50), with notes and an introduction.

Kottick presents technical information in an accessible, but entertaining, way: the forms and styles of harpsichords, advice on purchasing decisions, maintenance techniques (such as voicing, regulating, and changing strings, tongues, plectra, springs, and dampers), aids in troubleshooting common problems, and detailed instructions on tuning and temperament. As builder of some thirty keyboard instruments, Kottick is well qualified to speak on the subject.
