Are you a math nerd trying to get a grip on music theory? Are you already familiar with mathematical proofs? Then consider adding Neo-Riemannian to your toolbox

Heres a short video explanation,

Neo-Riemannian Music Theory Notes
A young musical theory set used to explain functions of narrow changes in existing songs 
Developed as a tool for musical analysis

"Major is a reflection of minor"
"Tonez Map"

music that uses triads without reference to key though "triadic atonality"
Triads are related only to one another through established voice-leading operations

operations (invertable)
Parallel: retained P5
Relative: retained M3
Leading: retained m3

secondary (combined operational steps)
N: preserves root
Slide: preserved median
Hexatonic...

Uniform Triadic Transformations (UTT)
+/-: +keeps or -inverse the mode of the input chord
x: n semitones to transition up if input is major
y: n semitones to move up if input is minor
x+y=n of semitones in scale (12)
