Fourths Tuning — Chords and Inversions

Standard tuning has a problem that most guitarists quietly accept and never question: the interval between the G and B strings is a major third while every other string pair is a perfect fourth. That single inconsistency means that almost every chord shape, scale pattern and arpeggio you learn has to be adjusted when it crosses that string pair. It’s a quirk of the instrument that creates an enormous amount of extra work over a lifetime of playing.

All Fourths tuning eliminates it. Tune the B string up to C and the high E up to F, and the fretboard becomes completely symmetrical — every string pair a perfect fourth apart, every pattern consistent across all six strings. The first time I tuned to fourths it was a genuine revelation: everything suddenly became more logical, more manageable, and more directly connected to music theory as it exists on every other instrument.

The tradeoff is that all your standard tuning chord shapes change. Fourths Tuning — Chords and Inversions is built specifically to solve that problem.
