An essential aspect of Neo-Riemannian Theory is chord transformation. This tutorial presents the 3 elementary Riemannian transformations (Parallel, Relative and Leading-tone exchange) and the compound transformations (PL, LP, PR, RP). Each of these is shown for major and minor triads in the Tonnetz diagram and staff notation. Transformations are interpreted in terms of the equivalent Schillinger Symmetric Harmony System Root Cycle, and demonstrated with a very short musical application example. There's a companion document with text, diagrams and score excerpts available in the webshop.
