A new theory for the resolution of discords, according to the Modern Musical System: by maestro Antoine Reicha

The passage from Classicism to the Romantic Era required a profound review of the Harmonic Theory. The principles of the new Theory were defined with simplicity and rigour by maestro Antoine Reicha, professor of Musical Composition at the Conservatoire de Paris at the time of Beethoven. This pamphlet aims to illustrate the principle upon which discords (dissonant chords) can be resolved when not following the natural law of resolution (which will also be enounced here). It also suggests how to conveniently employ such exceptions. This Pamphlet is especially dedicated to young composers, and to Professors of Music as a didactic aid.
