How to Tune to All Fourths (EADGCF)
All-fourths tuning (E-A-D-G-C-F) replaces the major third between the G and B strings with a perfect fourth, making every string a fourth apart. Scale, arpeggio and chord shapes become perfectly consistent across the whole fretboard, which is why jazz and fusion players like Stanley Jordan and Allan Holdsworth adopted it.
Start in standard tuning (E-A-D-G-B-E) and change 2 of 6 strings:
| String | Standard | Target | What to do |
|---|---|---|---|
| String 6 | E2 | E2 | Leave as is |
| String 5 | A2 | A2 | Leave as is |
| String 4 | D3 | D3 | Leave as is |
| String 3 | G3 | G3 | Leave as is |
| String 2 | B3 | C4 | Tune up a half step |
| String 1 | E4 | F4 | Tune up a half step |
String Tension & Setup Tips
Recommended Gauge:The bottom four strings stay at standard pitch. The B string is tuned up to C and the high E up to F, so use a slightly lighter top pair (.009 and .011) to keep the raised tension comfortable.

Frequently Asked Questions
How do I tune to all-fourths from standard?
From standard tuning (EADGBE), retune each string low to high: 6th E (unchanged), 5th A (unchanged), 4th D (unchanged), 3rd G (unchanged), 2nd B→C, 1st E→F. Match each string to its exact Hz using the interactive tuner above.
Why do jazz players like all-fourths tuning?
Because the interval between every pair of strings is identical, scales, arpeggios and chord shapes keep the same fingering anywhere on the neck. It removes the 'B string exception' of standard tuning and makes single-note lines very logical.
