The writing is practical, and no space is wasted on mere numerology....I have checked much of Donahue's arithmetic and not found any errors....No one who wants to understand temperaments should be in any doubt about how much systematic work is required, but Thomas Donahue's book goes a long way towards making it as easy and rewarding as it can be.

The British Clavichord Society Newsletter

Donahue, a musician and instrument builder, presents a handbook for keyboardists who tune their own instruments, such as the harpsichord, clavichord, and fortepiano. He explains the tuning process and related issues, historical factors, and theories including frequency, ratios, cents, fixed intonation, and the harmonic series. Sixteen temperaments are discussed and compared in detail. The second half of the book is a reference for specifics such as near-equal temperament, derivation of the cent equation, and has temperament data, spreadsheets, and instructions in musical notation.
