REGULAR TUNING / REFERENCE
All fourths tuning.
E A D G C F makes every adjacent string pair a perfect fourth. The lower four strings stay familiar; the top two rise by one semitone.

HOW TO TUNE
Set each string to its target pitch.
Strings 2 and 1 rise by a semitone. Recheck tuning gradually. This is E-based all-fourths, not an instruction to raise every string.
01 · String 6: keep E2; String 5: keep A2.
02 · String 4: keep D3; String 3: keep G3.
03 · String 2: raise B3 to C4 (1 semitone); String 1: raise E4 to F4 (1 semitone).
After each full pass, recheck all six strings with a chromatic tuner. Stop if a string feels unusually tight.
KEEP YOUR BEARINGS
Check notes before names.
A familiar grip can sound different after retuning. Read the tuning map and use the chord explorer before trusting a shape name.
Notes and fingerings are shown from string 6 to string 1.
WHAT ACTUALLY CHANGES
One interval between every adjacent string pair.
These are sounding pitches, shown from string 6 to string 1: E2, A2, D3, G3, C4, F4.
What transfers
✓ Strings 6, 5, 4 and 3 stay E A D G.
✓ Each neighbouring open string is five semitones higher.
✓ Patterns can move across string pairs without the usual G-to-B adjustment.
What needs checking
· Raise string 2 from B to C and string 1 from E to F.
· Standard chord shapes using those top two strings need checking.
· A regular interval pattern does not make every open-string chord transferable.
CHORD & SCALE EXPLORER
Start with E. Move from there.
Use the selected starter shapes, search another chord, or map a scale across frets 0 to 15. This explorer is set to All fourths.
These selected charts are the practical starting points for this tuning.
Familiar shapes appear first where available. Choose a shape that suits your hand. Where a fifth is omitted, the chart says so. For a first set to practise, open Starter chords.
The high string is shown at the top and the low string at the bottom. Scroll horizontally on smaller screens.
LOW STRING ANCHORS
Find the roots on string 6.
These are single-note landmarks, not six-string chord grips. Use them to locate a root before choosing a chord shape.

FIRST PROGRESSION
E minor → G major → D major → A major
Use the displayed shapes for one bar each. Observe the muted strings: leaving the raised treble strings open changes these chord names.
SCALE MAP
All fourths: find E natural minor.
On string 6, play frets 0, 2, 3, 5, 7, 8, 10, 12: E, F♯, G, A, B, C, D, then E.
Play the notes slowly in order, then reverse them. Keep the timing even and let each note speak.

Choose the same root and scale in the explorer to see the notes on all six strings.
The high string is shown at the top of the scale map. Each row follows one string.

What are the open-string pitches?
Strings 6 to 1: E2, A2, D3, G3, C4, F4.
What do the chord names mean?
They name the sounding notes in this tuning. A familiar fingering can have a different chord name after retuning. The fingering numbers run from string 6 to string 1; x means mute.
Can I use a different octave?
Use the octave numbers in the tuning map. A pitch-class match alone does not tell you that a string is in the intended octave.
How do I get back to standard?
Return strings 6 to 1 to E2, A2, D3, G3, B3 and E4. Recheck every string with a chromatic tuner.
