This paper discusses a quantitative method for the study of historical keyboard instrument tunings that is based on a measure of the perceived dissonance of the intervals in a tuning and their frequency of occurrence in the compositions of Domenico Scarlatti (1685–1757). We conclude that the total dissonance of a large volume of music is a useful tool for studies of keyboard instrument tuning in a historical musical context, although it is insufficient by itself. Its use provides significant evidence that Scarlatti used French tunings of his period during the composition of his sonatas. Use of total dissonance to optimize a 12-tone tuning for a historical body of music can produce musically valuable results, but must at present be tempered with musical judgment, in particular to prevent overspecialization of the intervals.
