Guitar Fretboard Mastery (Fret Science System)

A systematic approach to guitar theory emphasizing geometric patterns and understanding over rote memorization.

Core Concept: The Warp

The most important fretboard concept: the G-B string boundary shifts patterns by one fret.

• Standard tuning uses perfect 4ths (5 semitones) between strings, EXCEPT G-to-B which is a major 3rd (4 semitones)
• Any pattern crossing G↔B shifts one fret toward the bridge (G→B) or toward the nut (B→G)
• This explains why chord shapes change when moved across strings

Pentatonic Scale: Rectangle & Stack

The pentatonic scale is a 5-string repeating pattern with two geometric shapes:
