Neo-Riemannian harmony connects major and minor triads through small voice-leading changes rather than a dominant-to-tonic cadence. The three common transformations are P (parallel), L (leading-tone), and R (relative).
Each transformation changes one or two notes while preserving the other chord tones. Stringing them together creates smooth but surprising harmonic paths.
Hear a P transformation
The P move changes C major to C minor: the root and fifth stay, while E moves down a semitone to E-flat.
From C major, R leads to A minor and L leads to E minor.
Try it
- Start with a major or minor triad.
- Apply P, L, or R and identify which notes stay and which move.
- Chain two transformations, then choose a point where the progression should pause or resolve.
Key takeaway
P, L, and R provide a compact way to explore smooth major/minor triad changes without relying on traditional functional roles.
