Abstract
Musical transformation is an extremely broad, abstract explanatory concept, capable of covering not just instances of radical conversion but, in fact, all degrees of musical change. When it comes to rock, transformations are among the most powerful and talked-about musical effects. Many of these effects are harmonic, and this article seeks to give voice to a number of these. To this end, I will present several musical examples from the rock repertoire that will help clarify some common kinds of harmonic transformations, as well as some common kinds of harmonic structures involved in such transformations.
