Analytical lineages from Rameau (harmonic), Marpurg, Mattheson, Riepel, and Koch (rhetorical and melodic), fed by models from natural philosophy and biology, led to a rich array of descriptive analytical methods in the 19th c. The analysis of fugue, driven by basse fondamentale and Zergliederung (dismemberment), is exemplified in newly translated works by Momigny, Rejcha, Hauptmann, Sechter, Dehn, and Riemann. The analysis of form and style, harnessing old notions of rhythmic phraseology and cadence-type, and new notions of development, harmonic function, formal model, idea, and motive, is exemplified by Vogler, Rejcha, Weber, Czerny, Lobe, and Mayrberger. The classification of personal style, driven by old notions of style and manner, and new ones of childhood, adulthood, and maturity/decrepitude, are exemplified by Baini, Schlosser, Fétis, Ulybyšev, and Lenz.
