chromaticism

Franck's dense, modulatory harmonic language, derived partly from Liszt and Wagner but shaped into a distinctly personal style. Chromatic inner voices and unexpected enharmonic pivots are constant features.

Chromatic voice-leading in Franck requires that every inner voice be voiced as a real melodic line, not merely harmonic filler. Practise the chromatically moving inner voices in isolation to understand their direction. At the keyboard, give each chromatic step just enough weight to be heard without disturbing the melodic surface.
