This is the first in set of three weeks devoted to “Transformation theory,” a discipline that has its origins in the writings of David Lewin and which has had enormous influence on the current state of music theory.

“Classical” transformation theory is the subject of this week. Many of the most important readings in transformation theory, including Lewin’s treatise Generalized Musical Intervals and Transformations, are not included here, mostly because the technical apparatus developed there is very difficult to grapple with in a single week.

We will also deal this week, for the first time, with “post-tonal” music. Those of you that have never studied “pitch-class set theory” are urged to have a copy of Joseph Straus’s Post-Tonal Theory at hand, or my own post-tonal resources, collected in Open Music Theory.
