This section is based on Traité d’Harmonie, published in 1862 by Henri Reber, a 19th-century composition professor at the Paris Conservatory. Reber was highly regarded in his time—so much so that Chopin recommended him to his own students for music theory lessons. According to their correspondence, Reber was also the one who encouraged Chopin to study counterpoint.
Rooted in the sound traditions of the great masters, Reber’s treatise was designed to help students develop the skills to analyze their works. While it was intended primarily for analysis, aspiring composers will also find it an invaluable resource.
I’ve done my best to translate and present the material in a way that is accessible and clear for modern students.
