Theory
A library of music theory, written like an essay.
Long-form pieces — voice leading, the circle of fifths, the CAGED system, why a diminished chord sounds the way it sounds. Set in serif at a width you’d want to read for an hour.
“Hold what you can. Move only what you must.”
from On voice leading
The CAGED System
Five shapes you already know — C, A, G, E, D — contain every chord on the guitar. The fretboard past the third fret is fog. Here's how to clear it.
The Circle of Fifths Explained
The circle of fifths isn't a chart to memorize. It's a map: your I, IV, and V live next door, and distance between keys is drama you can dial.
Modes Explained — Ionian Through Locrian
Modes aren't seven scales — they're one scale heard from seven starting points. Meet each mode's signature note and the songs that live inside it.
Voice Leading — Hold What You Can, Move Only What You Must
Same chords, different motion. Hold the notes that can stay, move the rest by the smallest step — and a clunky progression turns smooth.
