A Plaine and Easie Introduction to the mathematics of tuning and temperaments
A SWEMF Zoom Workshop, held on 19th November 2022

Clare explains why it’s impossible to have every interval in a 12-semitone scale in tune at once, and looks at some of the methods which have been adopted to get around this problem.
