At just 34 years of age, Theodore Dubois was installed as a professor of harmony at the Paris Conservatoire. Whilst much of his compositional works have disappeared from primary classical repertoire, his teaching has had a lasting influence. Having taught successful composers, including Paul Dukas, it is clear that Dubois' Realisation of Figured Bass is well-informed.

This music theory study guide covers a considerable range of figured bass aspects, to a high standard. Taken from his Treaty of Harmony, Dubois explains the need for his treaty, stating that it fills the gaps in harmonic theory excerises which preceding guides had missed. With no harmonic elements left out with regard to figured bass, this Dubois theory guide is necessary to accompany all music studies.
