- Late 19th-century composers often used triadic progressions that confound conventional Roman numeral analysis. Neo-Riemannian theory explains such progressions through shared common tones rather than membership in a key. Its three basic transformations (Parallel, Relative and Leading-tone exchange) each keep two common tones and move the third note, and the most interesting combinations use parsimonious voice leading, in which no voice moves by more than a step.

Neo-Riemannian theory, named after music theorist Hugo Riemann, provides a means of rationalizing triadic progressions that involve sharing common tones, more so than staying within one key. ... The most basic Neo-Riemannian transformations shift one note and keep two common tones. ... In the late 19 th century, composers often used triadic progressions that confound conventional Roman numeral analysis. ... The most interesting are those that use parsimonious voice leading: voice leading in which no single voice moves more than a step.
