As one of the fundamentals in the study of harmony, particularly for Baroque music, Henri Challan (1910-1977) provides an imperative aid to the understanding of Figured Bass. Challan, a French composer and music educator was appointed Professor of Harmony at the Paris Conservatoire in 1936. He compiled 380 Figured Bass Exercises during 1960, after a considerable amount of time working in the field. With Challan’s experiences in mind, 380 Figured Bass Exercises is very well-informed. The first volume provides 90 exercises in which the student can practice the basics of the realisation of figured bass. Challan’s 380 Figured Bass Exercises is essential to all harmony studies, given that the realisation of figured bass remains an important part of music education.
