THE TUNEGUITAR GUIDE
Understand Open E
G sharp decides the major colour
E B E G sharp B E is an E-major chord without fretting. The third string rises from G to G sharp, while strings 5 and 4 rise a whole step. Leaving G unchanged creates Open E minor instead. Listen to the third string against the low E after the mechanical changes: that single semitone has a larger harmonic effect than its small peg movement suggests.
A lower-tension route to the same sounding chord
Open D with capo 2 supplies the same six sounding pitches. The capo route is useful when raising several strings is unsuitable, but it changes where playable frets begin. Tune Open D first with the capo off. Do not select Open E and then add capo 2 unless you actually intend to sound a further whole step higher.
Use a straight barre as a listening exercise
An open-major tuning preserves its chord quality when every string is stopped at the same fret. Compare open E major with a light barre at fret 3, which sounds G major. Keep pressure even and avoid pulling the strings sideways. A fretted chord that becomes sharp despite correct open notes can reveal technique or setup issues.
Your string-by-string route from standard
This is a comparison of target pitches, not a recommendation to use every tuning on every guitar. Start from the tuning your instrument actually has. Use the directions and the octave labels together.
| String | Start | Target | Adjustment |
|---|---|---|---|
| 6 | E2 | E2 | Keep this target |
| 5 | A2 | B2 | Raise 2 semitones |
| 4 | D3 | E3 | Raise 2 semitones |
| 3 | G3 | G♯3 | Raise 1 semitone |
| 2 | B3 | B3 | Keep this target |
| 1 | E4 | E4 | Keep this target |
